The High Voltage Battery Tester is a modular system whose functions can be customized according to customer requirements and test conditions. The HVBT system is integrated into the customer's functional safety systems in the assembly process. The HVBT controls the charging and discharging of the HV battery for production, transport and delivery.
Generally, testing of EV battery systems can be categorized into four stations in the production line that fulfil the following functions: 1. Battery Sub-Module Welding Test Systems: Quality checking the welding on various battery sub-modules 2.
To conform to such standards, the battery pack must pass safety tests such as the dielectric strength test, insulation resistance test, ground bond test, leakage current test…etc. In the industry, most companies use a single electrical safety analyzer to execute these safety tests.
Batteries go through an acceptance inspection before they are put together into modules and packs. This is because things like vibrations during shipping and even the passing of time can cause batteries to defect. It is necessary to keep the electrodes and enclosure (case), insulated from each other.
2. Battery Module End-of-Line (EOL) Test Systems: Confirming that each battery module is functioning correctly 3. Battery Pack In-Line (IL) Automatic Test Systems (ATS): Checking the functionality of battery modules before the external cover is installed 4.
And according to IEC 60950, the test voltage for a dialectical test is two times the operating voltage plus 1000 volts, which can damage other parts easily if it’s connected during the safety test. To protect the expensive equipment, the test system design experience and high-quality integration ability must be considered.
