Charge and discharge control |
After undervoltage protection, in the non-charging working state, BMS will force the delay into hibernation and turn off the charge and discharge protection switch;
Charging automatically activates the BMS and turns on the charge and discharge protection switch; RS485 The communication signal activates the BMS and turns on the charge and discharge protection switch; RS485 When the communication signal is interrupted, turn off the charge and discharge protection switch, and the BMS delay into hibernation. |
