Yousun Master, I am most thankful for your instructional video. I connected the balance charger to the same battery configuration as you did. The result is fantastic and unbelievable. I learned from you by watching this video. When I measured the voltage across the 3 large resistors, I didn't get any reading. But when a LED was connected (without current limiting resistor) across, it lit up exactly as in your video. The test was only for a few seconds, as I could not calculate the Current limiting resistor value. Therefore, I request you to let me know, how you calculated the CL resistor and what was the value. Thanks and regards.

I use HX-JH-001 balancer module, and there is indeed voltage across the board's big resistor once the channel is activated for balancing, in my case at 4.22 V. You calculate: supply voltage V(sup) less nominal LED voltage V(LED) equals voltage drop on LED resistor V(r). V(sup) - V(LED) = V(r) 4.22 V - 2.5 V (for yellow LED) = 1.72 V LED resistor R(LED) equals voltage drop V(r) divided by nominal LED current I(LED). V(r) / I(LED) = R(LED) 1.72 V / 0.020 A = 86 Ohm Balancing LEDs are not supposed to work for long time continuously in this case, so you can assume slightly higher current for momentary use, like 0.030 A - this is even still inside safe range. Then you'll get 57 Ohm. Also different LED colors have different ratings. In practice, you can blind choose any resistor between 50-100 Ohm. Should work. Moreover, LED's current adds up to balancing current. If my module is balancing nominally with 66 mA per channel and each LED is taking 30 mA, then I made my board modded to 96 mA per channel! Adding more LEDs + resistors per channel would make even better result. Thank you @Yousun for guidance!

@trabadix4 жыл бұрын
Sorry for my English, I will use the Google translator to do this quickly. The BMS have the peculiarity of protecting against overload, over discharge and over voltage, most of the BMS modules that come out to the market today have a mini load balancer, the bad thing is that they only do their job well when the difference The voltage between cells in series connection is minimal, that is, they have certain limitations due to the current that they can handle when they are small, about 10 or 20 mA, so the balance is made until the end of the load, the bad thing is that if a cell is bad, it is difficult to balance the load correctly. The source must be constant current and constant voltage, that is, a switched source or smps, a linear source will not work for you, because BMS only allow a certain voltage range to perform the charging stage, for example for 3S They are 12.6, but you could add up to 13, the bad thing is that the source tries to load up to that voltage, and therefore, the current will be so great that the balancer will not be able to do much until the moment one of the cells arrives at its maximum, at that moment it will stop charging .... And even if it tries to balance it will not be possible because there is no voltage and the BMS itself must be reconnected and it will not start charging again until the voltage source is disconnected and reconnect ... That is why it is a headache when a cell has been damaged, since for security the system disconnects and until the battery set is balanced again, it will be difficult to recharge the package ... The source only delivers constant current until it reaches its constant voltage, At this time the balancer will gradually adjust the voltage, drawing current through the dedicated load resistor. At this time when the maximum voltage of a cell is reached, the BMS will stop charging because it will reach its maximum load and if it needs to balance more, then it will begin to discharge one by one until they are balanced as precisely as possible, the bad thing is that If at that moment a cell is damaged in a configuration such as 3S2P, it will be difficult to adjust the balance without actually downloading the complete set. Lo siento por mi ingles, usaré el traductor de Google para hacer esto rápido. Las BMS tienen la peculiaridad de proteger contra sobre carga, sobre descarga y sobre voltaje, la mayoría de modulos BMS que salen hoy dia al mercado cuentan con un mini balanceador de carga, lo malo de estos es que solo hacen bien su trabajo cuando la diferencia de voltaje entre celdas en conexión en serie es mínimo, es decir, tienen ciertas limitaciones debido a la corriente que pueden manejar al ser pequeños, de unos 10 o 20 mA, por eso el balance se hace hasta el final de la carga, lo malo es que si una celda esta mal, difícilmente se podra balancear correctamente la carga. La fuente debe ser de corriente constante y voltaje constante, es decir, una fuente conmutada o smps, una fuente lineal no te servira, debido a que las BMS solo permiten un cierto rango de voltaje para realizar la etapa de carga, por ejemplo para 3S son 12.6, pero podrías agregar hasta 13, lo malo es que la fuente tratara de cargar hasta ese voltaje, y por lo mismo, la corriente será tan grande que el balanceador no podra hacer mucho hasta el momento en el que una de las celdas llegue a su tope, en ese momento detendrá la carga.... Y aunque trate de balancear no podra debido a que no hay voltaje ya que la misma BMS debera ser reconectada y no volvera a comenzar la carga hasta que se desconecte la fuente de voltaje y vuelva a reconectarse.... Por eso es que es un dolor de cabeza cuando una celda se a dañado, ya que por seguridad el sistema se desconecta y hasta que no se vuelva a balancear el conjunto de baterias difícilmente volvera a recargarse el paquete... La fuente solo hace la entrega de corriente constante hasta llegar a su voltaje constante, En este momento el balanceador ajustará de a poco el voltaje, derivando corriente a traves de la resistencia de carga dedicada. En este momento cuando se llega casi al máximo voltaje de una celda la BMS detendrá su carga debido a que llegara a su máxima carga y si faltara balancear mas, entonces comenzara a descargar una por una hasta balancearlas lo mas precisamente posible, lo malo es que si en ese momento una celda esta dañada en una configuración como ejemplo 3S2P, difícilmente podra ajustar el balance sin llegar a descargar el conjunto completo.

With the 19 in series I formed 5 stack and then connected them in parallel for my inverter use. So this now configured 70 volts instead of 351 volts it's was before. My question is, will the ECV it ca me with still work as BMS or do I need to in-store new BMS for bottom balancing.

It takes good factory cells in groups, about 100 charges to become 5 percent imbalanced, is that right? then after 100 charges you can re balance them usign accucell or a dedicated balancer.

Got it. What's the rule behind choosing Balanced & Protection IC ? You have choose only slightly different voltages 0.01V Protection vs Balance, is this enough margin? Some variants of protection ICs have hysteresis between Overcharge Detection & Release Voltage (VCU & VCR), other have the same (VCU=VCR), why? The same is for Balance IC, they can have the same VCU & VCR or a hysteresis . What is 0V Battery Charge Function?
Yousun, can this solution be used to build an 12V batterypack of 200 Ah? if so, how?
@yousun28275 жыл бұрын
Yes, but this BMS has a continuous discharge current of only 30A. With a 200A battery pack, the equalization current needs to be larger.
@tomashermansson68985 жыл бұрын
Yousun my current idea is to build several packs and connect them in parallell. 3x5 cells with an BMS. I assume I will need approx 15-18 packs to deliver 200 Ah. Alternatively I build fewer but larger packs. How do I calculate the max A that an pack can deliver?

Hi, great job! I have made miself a 3s2p Li-ion replacement batery for my cirdless drill. All of the cells were precharged and ballanced at 0.01 v diff. Hooked it up to the drill, when i press the trigger the voltage drops to 0 at the discharging terminals of the bms. The bms is ratted for 60 amps max. Do not think it reached that high. The drill works with former battery pack. Rotor not in sort circuit. Can you please send your opinion on ehat could it be? Edit: jost noticed that if I jerk the trigger really quickly it works. No more voltage cut. But no low speed, only full throtle. :(
@yousun28275 жыл бұрын
Generally it is a BMS problem. If the MOSFET supports a large current, add a BMS sampling resistor.
@ciprianusurelu55195 жыл бұрын
The shop where the bms is sold had this to say: "When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube." I think the capacitor will do the job, but what does he mean by "brake the MOS tube"? And is 100uF enough to rotate the drill?
