Selection of BMS board:

1. Determine your battery type (ternary/NCM, lithium iron/LFP, lithium titanate/LTO) and determine the number of strings and parallel to 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 different ports. The same port is the same wire for charging and discharging, but separate ports one for Independent circuit of charge and discharge thought.

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 fact. We use this theoretical value as a reference. Considering the load, uphill and just starting environment, there are generally more choices for two-wheeled electric vehicles more than twice the theoretical value. Three-wheeled electric vehicles choose more than 3 times this theoretical value. four wheels 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. ensure. The current value of the shield must be larger than the control current limit value.
