The invention provides a distribution automation terminal battery management test system. A BMS module is connected with a control module; the BMS module is used for controlling a lithium battery pack to charge/discharge by controlling on/off of a first switch and a second switch, monitoring charging and discharging current and voltage of the lithium battery pack, and sending the monitored charging and discharging current and voltage of the lithium battery pack to the control module; the charging and discharging current and voltage of the lithium battery pack obtained by the control module, operation data information of a charging and discharging machine and operation data information of the BMS module are transmitted to a PC; and the PC displays the obtained data information, and compares the charging and discharging current and voltage of the lithium battery pack, the operation data information of the charging and discharging machine and the operation data information of the BMS module with threshold values respectively to evaluate performance of a distribution automation terminal under test. The system can detect and display relevant information of the BMS module in real time, and simulates state parameters of current, voltage and temperature of the lithium battery to detect function state of the BMS module.
