Li-Ion Battery BMS Description:
How to choose the right BMS board?
1. Determine your battery type (ternary/NCM, iron lithium/LFP, lithium titanate/LTO) and determine the number of strings and parallels of the battery pack. Choose according to the number of series
2. Determine whether the battery pack is charged and discharged in the same port or in separate ports. The same port is the same line for charging and discharging, But the separate port is for charging and discharging through independent lines
3. Determine the current value required by the protection board: I=P/U. That is,current=power/voltage. .
Remember this is only a theoretical value. In reality. We use this theoretical value as a reference. Taking into account the load, the uphill and the environment just started, Generally, the two-wheel electric vehicles choose more than 2 times this theoretical value. Three-wheeled electric vehicles choose more than 3 times this theoretical value. Four-wheel low-speed vehicles generally have about 3.5 times. For inverters and energy storage products, 1.2 times is enough. Or refer to the current limit of the electric vehicle controller. Guarantee. The current value of the guard plate must be greater
then the control current limit value.

Q:1. What is the balance function?
A: The working principle and function are as followings when your one cell voltage is up to alarm voltage(Li-ion up to 4.18V, Life Po4 up to (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will start a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po43.6V)are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage (Li-ion 4.25V, Life PO4 3.75V)BMS starts off power protection, all the other cells are all in the stop of charging, this process will enable your battery charging in balance current, and your battery voltage are in balance status, but when your cell voltage difference are in a big range, then the balance can not be functioning. well
Q:2. The relationship between Battery capacity and BMS current?
A: There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but relies on
continue current, that is to say, if your engine is powerful, you should choose a high current of BMS, it does not rely on battery capacity.
