Cycle Life Testing
Life is one of the most important indexes of a battery.Take Lithium-ion battery for example,the lithium-ion battery works on ion movement between the positive and negative electrodes,with increase charge/discharge cycles,internal resistance,elevated temperature and aging decrease the movement and in turn putting an end to the battery life.Battery manufacturers take a conservative approach and specify the life of battery most consumer products as being 300 to 500 charge/discharge cycles.IEC for a standard lithium-ion battery that the remain capacity after 500 charge/discharge cycles must be 60% or more.Battery life cycle number is influenced by charge/discharge rate,working temperature,environment and other factors.NEWARE battery testing equipment support 65535 times(one charge+one discharge considered one time)battery life cycle testing with high precision and 365 days Uninterrupted work.
EV are powered by batteries. User behavior while driving EV highly affects battery performance, and even its cycle life. Therefore, it is necessary for EV batteries to pass the Variable Power Discharge Test before they are released to the market.
Neware Battery Testing System has the function of“Drive Simulation Test”,it is used to assess the performance of EV batteries in actual on-road driving conditions and allows users to import battery charge/ discharge patterns from a real test drive.
