Auto Lithium Battery Large Current Short Circuit Test Machine

Battery Short Circuit Test Equipment Application

Relevant standards requirement

1. Test object: battery pack and system

2. Test conditions:

• The test temperature should be at 20±10ºCor higher. (According to the battery system manufacturer's request).
• All protective devices that affect the function of the test objects and related to the test results shall be in normal operation when the test starts.

3. The main contactors used for charging and discharging should be closed to indicate the feasible vehicle mode and the mode of allowing external charging. If is it not available to be completed in one single test, process two or more tests.

4. The positive and negative terminals of the test object being connected to each other to create a short circuit. The resistance of the connection (including wiring) used to create short circuit should not exceeding 5mΩ.

5. Keep short circuit until any of the following conditions are met and the test is completed.

• The protective function of the test object works and the short circuit current is terminated.
• After the temperature of the test object's shell is stable (the temperature gradient is less than 4ºCwithin 2h), the short circuit will continue for at least 1h.

6. After testing, observe for 2h under room temperature.

Main Features

• Vacuum Interruption, avoid electric arc to occur damage of contactor.
• Oxidation resistance condition of the main contact parts, ensure long operation time for high current and resistance.
• Data Acquisition: Temperature, voltage and current acquisition channels (Available for multi-channels.)
• Control Mode: Touch screen control + computer remote control + Remote controller.

Battery Short Circuit Test Equipment Standard

• UL 2580
