What is included in the automated testing of energy storage power supplies?
Energy storage power supply is a power supply that can store electric energy through batteries or other energy storage technologies and release the stored electric energy when needed. It has the two-way functions of "electric energy storage" and "power supply on demand". The core is to achieve flexible storage and release of electric energy through efficient energy conversion and management. It is widely used in energy storage, backup power supply, renewable energy consumption and other scenarios. Therefore, in the automated testing of energy storage power supply, functional testing, performance testing, safety testing and reliability testing are usually covered.
Energy storage power supply test
1. Function test
Charge and discharge function test
Fast charge, slow charge, constant current / constant voltage charge and other function tests
Constant power discharge, load adaptive discharge and other function tests
Battery voltage, current, temperature test
Battery overcharge / over discharge voltage, current limit test
Energy storage power supply test software
2. Performance test
