BMS WIRE DIAGRAM
Precautions for smart BMS:
1. The connection sequence of the smart BMS
The wiring sequence of the cable is the same as the hardware board. After confirming that the cable is soldered correctly, and the accessories that come with the product (such as: temperature control standard/power board option/Bluetooth option/GPS option/display option/custom communication Interface optional)
Install on the BMS, and then plug the cable into the BMS socket; the blue B-wire on the BMS is connected to the total negative electrode of the battery, and the black P-wire is connected to the negative electrode of the charge and discharge.
2. The BMS needs to be activated for the first use
Method 1: Activate the Power display panel, there is an activation button on the Power display panel.
Method 2: Charge activation.
Three, parameter modification
The number of strings of the BMS and the BMS parameters (Li-ion BMS, LiFePO4 BMS, LTO BMS) have default values when they leave the factory, but the capacity of the battery pack needs to be set according to the actual capacity AH of the battery pack. If the capacity AH is not correct Set, the percentage of remaining power will be inaccurate. Other protection parameters can also be set according to the customer's needs (It is not recommended to modify the parameters casually).
