Or what combination would you recommend? I am not an electrician but was told that accurate voltage sense is critical to accurate charging as just and few tenths voltage sense differential has a huge impact. A small relay is required to turn on and off the regulator since the BMS "allow to charge" signal is not capable of supporting any real load. The buck a boost 100amp does the job but is more than I want to pay, so is the Multiplus for that matter and I don't think the alternator is fussy like the sprinters are but I could be wrong. Stable and ideal output voltage keeps a lithium battery in it’s ideal charging range. The ideal charging voltage for Lithium batteries is 13.9-14.2VDC. 1- 3-12v lithium 50ah troll motor batta-36v When it does get to the full voltage the BMS (Battery Management System) needs to shut off the charge to the battery. The more lights you add the dimmer they get. You can use your alternator to charge the start battery and then use a DC DC Charger to charge the Lithium. How is this connection made? The alternator is externally regulated by a Balmar MC-614. I'm interested in putting lithium on my yacht. The 12/200 BMS is for Victron batteries only. Again, as before, the alternator always has a backup battery to charge. I need it as a current limiter to solve altenator heating problem when charging LiFePo4. Which Cyrix would you use – the Li-ct, the Li-Load or the Li-charge? This temperature probe will alert the regulator to an impending overheat scenario, at which point the regulator will reduce the load placed on the alternator. Is there a signal I could wire from say a BMV-712 or CCGX? Figure 4 In the layout above the alternator is charging a conventional start battery at all times. People try to buy this for use with other batteries but it will not work in that application. In this case there needs to be another conventional battery, usually a start battery, for the alternator to charge. if you have a battery with an external BMS then you can use the Cyrix-Li-Ct to be the combiner between your start battery and your lithium battery. Paul, Hi. How you suggest to charge 24v alternator to 24v truck wet batteries (maybe lithium in future) to 24v house lithium bank that is also tied to solar and or wind (expedition boooooon dock camper), The new range of Victron Smart DC DC Chargers will be available shortly to take care of charging one battery from another, whether the voltage is 12 to 12, 24 to 24, 12 to 24 or 24 to 12 there will be a programmable three stage DC to DC battery charger available to do the job. You can program how it behaves, for instance you can use its built-in vibration sensor so it only turns on when it senses that the engine is running. Most manufacturers offer a second alternator option, better known as PTO or Power Take Off option. The alternator is externally regulated by a Balmar MC-614-H regulator. As the fuse nears its rated capacity it begins to heat up and its resistance changes. This feature was added so you could install it with a minimum of interference to the vehicles wiring (and thus avoid any warranty issues). Alternators are rated under the most favorable circumstances (when they are cold) but once they get hot the performance drops off considerably. This 12/1200 BMS can be used as a current limiting device even if it isnt being used as the BMS that controls the batteries. I am building a camper van now. Lith-ion batteries are not always compatible with an OEM (or OEM-style) rectifier/regulator. The setup includes a temperature sensor on the alternator which limits its output by keeping the alternator within the allowed temperature. For customers with existing Max Charge TM Regulators who are adding LiFePO4 batteries, consult our website or call Balmar Tech Support to learn how to setup an appropriate charge profile.” Balmar Max Charge TM Regulators with the lithium program are shipping immediately and are available around the world through its business channel partners. John takes a look and comes away impressed. To avoid interfering with the vehicles electronics, which might cause warranty issues, the buck boost converter can be programmed to use its built in vibration sensor to only operate when the engine is running. For any other alternator it would be wise to consider some kind of limiting to prevent it from self destructing when charging Lithium Batteries at high output for an extended time. The Buck Boost DC DC Converter acts like a charge relay in this case. A discussion on the best way to incorporate an alternator into a Lithium-Ion battery system. As with all our Lithium Ion batteries, the … We’ve posted about it b, 2x 150w panels on top of the Alucab tent, Victron, Het hart van een off grid camper, de elektrische i, We want to wish everyone a very merry Christmas an, We cant get over how great this van is from wegfah, Con 525w en paneles fotovoltaicos la bateria de Li, Had a few people asking to see the layout in this, Finishing up some final wiring on the grey water t, field test and the results are specific for this installation on this location, Planning a transatlantic family adventure, New Product: Orion-Tr Smart DC-DC charger, Alternator rectifier diodes failing because of over voltage after disconnect by a BMS. Ta Just at the end of the charge cycle the voltage will rise and you want to make sure you dont allow it to rise above what is allowed for the AGM battery. And some very smart... Victron Energy Tech Talk Episode 3 now available! The RMSTATOR regulator has a carefully set output voltage of 14.1VDC (+/- 0.1VDC). The WS500 is the only alternator regulator available that can utilize current, voltage and temperature to deliver the most precise and effective charging possible for 12V, 24V and 48V battery systems – with configurability for voltages in between – making it the perfect solution for charging lead acid based, or new generation LiFePo4 lithium ion battery banks. Note that the alternator always has a conventional battery to charge even when its output to the lithium battery is interrupted. The solar-to-house battery voltage needs a voltage regulator for lithium batteries. Advanced electronic regulation ensure battery charge voltages are appropriate for all advanced battery types (including Lithium-Ion). Also please note that any links provided may be part of an affiliate programme (viz. Lithium battery regulator with a carefully set output voltage of 14.1VDC (+/- 0.1VDC). How does the victron VE BMS integrate with batteries without any communication from the internal BMS to the battery? If you have any input on that setup I would be glad to hear it. There are a few things to consider when incorporating an alternator into a lithium-ion battery system. What components would this kind of system require? Designed for a snug fit around our PS-09, this versatile laser cut tray is the perfect solution for securing the battery during racing. Thanks for the help, when the engine isn’t running and the starter voltage starts to drop much like Hi Peter, I'm starting to develop a 1000Ah Lifepo for my van conversion. Regarding the second diagram, and Ryans question. Your Price: $550.00 WS100 12V or 24V Multi-Stage Voltage Regulator. Thanks! alternators were controlled via MC614s . My question is specific to this post and designing a alternator charging system which can accommodate LFP.

I was an early 2012/13 adopter of LF04's with an external custom BMS by Demitri when he was still building them. The bigger the boat the harder that is to achieve and I have come to the conclusion that it isn't a very good option for anything except boats with outboards. Despite endless research, I am still baffled as to what I should use to isolate the two batteries. It will be charging two different battery types (AGM and lithium) times. These automotive style alternators offer many advantages. Again, which Cyrix would you recommend? That's a lot of batteries for a Van! The video in this blog highlights these lithium challenges and shows you what can happen when things go wrong – namely alternator overheating, smoke and an expensive alternator replacement, not to mention the risk of a battery thermal event. With this you can use a 24 volt alternator to charge a 12 volt battery or vice versa. Victron Energy SmartSolar MPPT 75/10, 75/15, 100/15 & 100/20; Victron Energy SmartSolar MPPT 100/30 & 100/50; Victron Energy SmartSolar MPPT 150/35 A battery-to-battery charger? Interesting discussions take place on our Community Pages all the time, offering glimpses into how Victron products are used in the real world. All lithium & some AGM applications require special programming of the alternator regulator. I plan to set up solar panel 320 W; but am curious if I can just start alternator alone first, and later adding solar? Alternators & Charge Regulators. What would you pair with the multiplus to convert from 12v to 24v that would be able to take advantage of the big alt and keep everything healthy? You say open the power circuit. Regulator Rectifier for lithium batteries; Which regulator rectifier to use with a lithium battery? That would require you to set the parameters to give you more cushion. Tis has an indépendant alternator to the bus systems, which is used to provide power to heating systems, TVs etc. I am looking at a brand of lithium which has an internal BMS but no way of communicating information to the outside (as it looks like the Victron batteries do... no CAN bus or extra wires hanging out, just terminal post). I want to use a buck boost dcdc On a 2500 Ram Promaster and it has a 180amp alternator in it. We carry regulators for both lead and lithium systems. An alternator regulator adjusts the output of the alternator to the proper voltage required by the batteries based on battery chemistry & environmental factors. See the clipped voltage output of a 3 phase system in Figure 4 below (green line). That's a lot of batteries for a van. When the battery gets full the BMS needs to shut off the charge. Exactly the information I was looking for!!! It takes the input voltage and changes it to whatever voltage is required by the Lithium Battery, and in the process limits it to the programmed value, up to a maximum of 50 Amps. A Lithium Ion battery can put a lot of load on an alternator and have it working flat out for an extended time. Thank you for your advice. Thank you Joe. Valence documentation says they are particular and require their hardware, which im having trouble locating. When you buy a Battle Borne or Relion battery they dont tell you how difficult it will be to hook it up to an alternator, this is a very difficult problem and there is no easy answer. The start battery is connected to the Lithium Ion battery via the Cyrix-Li-Ct which is a battery combiner controlled by the BMS. Rick's part # 14-103 is a plug n play piece for Vintage Honda Street Bikes with the following OE #'s: 31600-MA6-910, 316-MA6-000, 311600-MA7-008, 31600-425-008, 31600-461-771 or 311600-MG5-000. 4.2 Charge voltage. That would be the kind of heavy duty truck alternator that is designed to run at high output all day. What a great article. 2-2-12v lead cell house batts 12v system I shied away from my first choice of lithiums because of lack of knowledge with how to control the alternator issues with the Etec Outboards. In the first installation the engine – a low-revving marine diesel- has a dedicated starter battery and 50A alternator and a separate 160A alternator to charge the service batteries. If I chose a AGM start battery I think I should be able to program the alternator with a LiPo profile and just let the start battery live with the results. By the way, the alternator is a Valeo 439753 which is regulated and I currently have an 80Ah battery as my main battery and also a split charger relay. This is especially appropriate to Sprinter and EuroVans and other vehicles with high tech alternators. Protect your investment in an expensive lithium battery with our lithium battery voltage regulator! As a result the combination is not ideal for fast and full charging of other batteries, especially if you want to charge the batteries over a short time or when powering a heavy load. The promaster has a 180amp alternator. I did have a quesrion about all these systems, what happens when the engine is stopped? This ,as has been mentioned before,is the sticking point for an adequate install. Thanks! How is the vibration sensor connected to the Buck-Boost (this is not mentioned in the Victron documentation)? Bespoke laser cut lightweight aluminium mounting bracket to suit our PS-09 Lithium Ion battery. Hello Peter, I'm planning a boat system where the alternator is only charging the Lithium battery. The last way shown below is the most hi tech (and the most expensive) It was designed for use with the type of smart alternators and dynamos used on vehicles such as the Sprinter Van and Euro Van where the output voltage can vary dramatically. Lithium batteries also have their peak performance when they spend their life at a partial state of charge. The Tracer BP series solar charge controller adopt to the advanced Maximum Power Point Tracking charging methods, it enables the system charging and discharging management to obtain the most radical optimization. You would require some external relays in addition. my goal is to be able to charge the system in 2-3 hours of driving. 1. Will I be able to connect a Cyrix circuit from Lithium BMS to the main starter battery? voltage sensing for both the main bank and the buffer(starting batteries especially if an isolation event occurs underway. Is there a way I can contact you for (paid) input on an install? This combination is suitable for all battery types, including Lithium Ion. You can use their output to control loads and charge sources. It works by putting a fuse of the desired limit in the BMS. The second installation is as above but using the VEBus BMS and 3xVictron 150Ah LiFeP04 Smart batteries in parallel. I haven't personally done it this way but I don't see what it wouldn't work. Lithium batteries have a maximum charge current and a recommended charge current. In fact, the alternator regulators that have been available to us cruisers for about the last 15 years are not that bright…OK, they’re downright stupid. The battery will not limit the current in any way and behaves like every other lithium battery. Finished with a tough powder coat and water-resistant conformal coating, each alternator is designed for operation in harsh environments. I want a separate Lithium battery in truck camper with solar charge input. Thank you for that suggestion. They said using the above Sterling charger, it would be fine, but I want to be sure. The purple wire in the drawing is the "allow to charge" wire from the BMS, it is a +voltage signal that it is OK to be on. Im not sure if the diagrams would be directly compatible or what modifications would be needed. Wakespeed alternator regulators paired with the OPE Tether deliver cutting edge functionality that is not available through any other manufacturer. When the battery is full the "allow to charge" signal turns off and so does the regulator and therefore the alternator. On the plus side, I won't need as heavy a gauge of wire. I could see using a lithium program due to the fact that most of the charging time will be on the house bank but will that program harm the start battery? When the alternator gets too hot the regulator dials it down a bit to keep it within the allowed temperature. Pin 1 can be used to switch the unit on (in place of the vibration sensor), but the Victron documentation makes no mention of pin 2. It will take all the charge you can provide. Advice? There might need to be some way to limit the demand to prevent the alternator from self destructing. Charging and recharging simply moves lithium ions from one side of a membrane to another. Bigger picture, how does the Buck-Boost communicate with the rest of the Victon components? You might as well program the system to suit the Lithium battery as it will dominate what happens. In this next diagram (above) the Victron 12/1200 BMS is used and this has a built-in way to limit the alternator to up to 100 Amps depending on what size fuse is placed in the left hand fuse holder. In the next drawing, below, the alternator is only charging the Lithium battery. At the time of writing (December 2019) the first few are now available and the rest should be here within a couple of months, Hi everyone, I purchased 8 Valence U27-12xp lifepo4 batteries([email protected] each) for a Promaster van conversion intended for full-time off grid use. A combiner is a relay, but it does not prevent over-charges. This BMS operates on the negative wire of the circuit and to avoid bypassing the BMS loads in the circuit need to have isolated negatives, either by not sharing a common ground (vehicle chassis) or by being connected via an isolated DC DC Converter. my question, I want to understand how to size the alternator for this size of a system? The carefully dedicated voltage sense wires (of equal length) were run directly to the LFP04 bank (with twin Victron multiplus 3000's)and once bank was isolated could not provide charging(effect) feedback information. Great post! I no longer have that boat .but am upgrading batteries in a new outboard powered boat (to me Rosborough). Because they are just looking at the voltage of the bank as a whole and not at an individual cell level it doesn't give quite the same level of control as you get with an external BMS. The Alt B+ to the battery while fused will always be connected. 1) What are the options if the batteries have an internal BMS? I am running two AGM batteries with ML-ACR on 140A alternator. In the first scenario (start and house bank separated by Cyrix-Li-Ct) how do you program the voltage regulator on the alternator? All Rights Reserved. Using DC DC Converters for power conditioning. So the limitation on current is not the battery itself but a limitation of the switch. Thank you!!! In fact i notice this with a lot of LFP lithium batteries on the market. 12V 165 and 200A output. Balmar Multi-Stage Voltage RegulatorsOptimize Your Charging System Max Charge MC-614 Voltage Regulator 8 Selectable Programs for Marine Batteries (including LiFePO4) 15 Amp Maximum Field Current Advanced Programming Modes Alternator & Battery Temperature Sensing & Control Exclusive Belt Load Manager Function Bright LED Display and Easy Programming Mode Can be Used in Twin … If you want to limit the alternator to 80 Amps you put in an 80 Amp fuse. Charging lithium batteries from an alternator, be that in a boat or vehicle, presents some challenges when compared to the straightforward nature of charging lead based batteries. I'm a bit confused on Alt shutdown with Battery protect. I have a new 12V 100A Battle Born deep-cycle lithium iron battery that I want to charge using the 90A alternator (via the 12V lead-acid starting battery) in my VW Vanagon camper. I don't know all the details of how it works but I would imagine that when it says it limits transient voltages all it means is that the unit contains a capacitor which would have the effect of smoothing out spikes. Or just using alternator alone is bad idea? Victron 24V Lithium Batteries part of our Victron Lithium battery ranges from onBoardEnergy a leading stockist of Victron batteries In the meantime make sure you are using the right tool for the job – all of which can be discussed on the Victron Community. 2x KS100 100Ah lithium batteries testing alternator current draw What would you recommend as a work around to have best most accurate.
