The tester for power lithium-battery protection board is researched and developed independently by the Company, filling current technological gaps at home. Moreover, it is applicable for test of lithium-battery protection board, and equipped with PC-based IPC, with easy, intuitive and reliable operation, which controls the internal multi-circuit relay for channel switching via PLC. And the normal operation of protection board will be achieved by overcharge protection voltage, overcharge recovery voltage, over-discharge protection voltage, over-discharge recovery voltage, over-current protection, short-circuit protection performance test, over temperature protection of charge and discharge, total self consumption current of protection board, and self consumption current of single battery. Products enjoy smudge-proof, moisture-proof, anti-corrosion, anti-vibration features and resistance to high and low temperature (-25â - 85â), and can work under harsh environments therefore.
