Power characteristics are an important performance indicator of EVs, as well as an important indicator of EV battery cells. HPPC test, short for Hybrid Pulse Power Characterization Test, refers to the test of discharging and feedback (charging) pulses within the range of current and voltage available to the battery to characterize the dynamic power capability of the battery. The main purpose of th...

The battery cell energy efficiency refers to the percentage of the discharge energy to the charging energy in the battery charge-discharge cycle under given conditions. Generally speaking, charging and discharging cycle tests are performed on battery cells under different temperature conditions, so as to obtain the energy efficiency of the battery cells. The following table is a simple battery cel...
