Energy Storage Battery
Type tests according to standards and performance baseline tests based on customer requirements.
Unlike traditional power batteries, energy storage batteries have relatively lower requirements for energy density but place greater emphasis on capacity and cycle life. As the capacity of single cells continues to expand and enter production, testing and verification of their mechanical properties, safety performance, and environmental reliability are essential.
As the core component of an energy storage system, the energy storage battery directly determines the system's capacity and efficiency. Its energy density, charge/discharge efficiency, and stability affect not only the performance and stability of the energy storage product but also the safety and reliability of the system. The laboratory is equipped with professional testing equipment such as battery performance test systems, multi-channel battery pack, cell/module/cluster charge/discharge test systems, and safety test explosion-proof rooms. We provide comprehensive testing services for battery packs, modules, and cells, covering environmental adaptability, safety performance, electrical performance, and EMC.
Environmental Tests: Mechanical shock, vibration, impact, high temperature/high humidity, salt spray, temperature cycling, low air pressure, thermal shock, damp heat cycling, etc.
Electrical Performance Tests: Initial charge/discharge energy, rate charge/discharge performance, high/low temperature charge/discharge performance, energy retention and recovery capability (room temp & high temp), storage performance, insulation and dielectric strength, cycle performance, adiabatic temperature rise, etc.
Safety Performance Tests: Over-discharge, overcharge, external short circuit, crush, thermal runaway, nail penetration, drop, etc.
EMC Tests: Electrostatic discharge, radio-frequency electromagnetic field, electrical fast transient/burst immunity, surge immunity, radio-frequency common mode, power frequency magnetic field, etc.
