1. Scope of application:

It is applied to the integrated charge discharge cycle test system of low string lithium battery pack cycle charge and discharge, battery pack function test and charge discharge data monitoring, such as electric tools, solar energy storage, fascia gun and so on.

2. Environmental requirements and technical parameters of equipment:

2.1 power supply: AC voltage 220V ± 10%, frequency 50Hz ± 10%;

2.2 ambient temperature: - 10 ~ 45 ℃;

2.3 the environment is free from strong vibration, corrosive gas and flammable and explosive gas.

3. Function introduction:

3.1 charging and discharging function: it has the functions of constant current and constant voltage charging and constant current discharge. It can charge and discharge the battery and record the battery capacity;

3.2 charging and discharging interface: fully meet the requirements of the same charging and discharging port and charging and discharging sub port of the battery pack, i.e. two wires (P + P -), three wires (P + P - C -), electric tool battery with positive plate charging protection and negative plate discharge protection (CH + P + P -);

3.3 check the voltage protection: check whether the charging protection and discharge protection of the battery work by charging and discharging the battery;

3.4 safety protection: anti reverse connection protection function, power failure data protection, support continuous measurement, voltage upper and lower limit setting protection, and safe discharge current protection;

3.5 online mode: single instrument or less than 5 instruments can be connected to PC through serial port; More than 5 sets adopt the network connection mode, and the PC terminal provides a network port to control less than 30 instruments;

3.6 control system: the software system adopts the classic and mature C / S mode, and the communication modes include serial port and network. The serial port can realize the accurate communication of several instruments in a short distance, and the network can realize the accurate communication of multiple instruments in a long distance;

3.7 management software: Based on the windows operation interface, the SQL database is used to store the test data, which is very convenient for the staff to query and export the data online. The charge discharge aging curve can be viewed according to the battery bar code, time and equipment number, and the curve can be exported at the same time.
