Safety of Battery
- BMS installation should pay attention to electrostatic protection.
- Make sure the battery series is consistent with BMS before BMS installation.
- During the installation process, the total negative electrode of the battery should be connected first, and the PACK wire should be connected to the battery and confirm the correct sequence before plugging in the BMS.
- After the completion of battery installation, it shall be communicated firstly to confirm the correct battery assembly before charging and discharging, and a full charge and a full discharge shall be guaranteed.
- In order to ensure the stability of the system, the key indicator light between the small board and the main board of the wire should not be greater than 50cm.
- Please do not modify the configuration of BMS parameters by yourself. Please contact the manufacturer if necessary.
- All protection parameters should be configured strictly according to the actual conditions of the battery, or it may cause danger.
Please pay attention to the following：
- If the short circuit current setting is too large, because the battery capacity is small, the discharge rate is small, the battery internal resistance is large, and other reasons, even if the positive and negative poles of the complete short circuit cannot reach the short circuit protection current, resulting in battery damage。
- If overvoltage protection parameters are too high, the battery will cause unrecoverable damage due to overpressure, and serious will lead to battery damage。
- If voltage protection parameters are too low, the battery to discharge, leading to irreversible damage。
- If the configuration parameter exceeds the limit parameter of the protective plate, the BMS and battery will be damaged.
