How to choose the right BMS board?
1. Determine your battery type (ternary/NCM, lithium iron/LFP, lithium titanate/LTO) and determine
The number of strings and parallels of the battery pack. Choose according to the number of concatenations.
2. Determine whether the battery pack is charged and discharged in the same port or in different ports. The charging and discharging of the same port is the same line, but a separate port is an independent charging and discharging line.
3. Determine the current value required by the protection board: I=P/U. That is, current = power/voltage. . Remember that this is only a theoretical value. In fact. We use this theoretical value as a reference. Taking into account the load, uphill and just starting environment, generally two-wheeled electric vehicles choose more than 2 times the 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. ensure. The current value of the guard plate must be greater than the control current limit value.
