One of the main challenges associated with fast charging and discharging is the degradation of the battery’s electrodes, resulting in decreased battery capacity and increased internal resistance. Rapid charge/discharge rates can also cause high heat generation, leading to thermal runaway and damage to the battery’s electrolyte and electrodes.
Reducing charging times and increasing vehicle range are desirable for better battery performance and lifespan. One of the main challenges associated with fast charging and discharging is the degradation of the battery’s electrodes, resulting in decreased battery capacity and increased internal resistance.
Discharge rate is a key factor that affects battery performance. Under constant discharge rate test protocol, the voltage is lower, the discharge duration is shorter, and the discharge capacity is lower at high discharge rate. However, the capacity difference caused by discharge rate change does not represent battery performance divergence.
However, the capacity difference caused by discharge rate change does not represent battery performance divergence. For a specific battery at a certain moment, its performance is determined, and it has to transfer capacities to the same criterion and the comparison of capacity without mentioning discharge rate is unreasonable.
Capacity diversity due to discharge rates and its retention upon cycling The discharge curves (measurement of battery terminal voltage v.s. capacity) at four discharge rates in a four cycles loop are shown in Fig. 2 (a). From the beginning of the discharge process, the battery voltage decreases along with the increase of depth of discharge.
The constraint on the charging and discharging power of EV batteries is shown in Equation (15): where is the maximum discharge power of the battery. is the maximum value of battery charging power. The specified discharge power is negative and the charging power is positive.
