To further analyze the relevance of the charge–discharge switching interval and heating rate, experiments under an initial temperature of −20 °C, a SOC of 50%, and a
Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
From a practical point of view, the application of pulse charging–discharging strategies for LIBs are the trade-off between the charging time and the capacity fade of batteries. area of the electrode (m 2). concentration of lithium ions in the active material particles (mol m −3).
This charging strategy has advantages of short charging time and high utilization rate of battery capacity [6, 7]. In contrast, a charging strategy of pulse current-constant voltage (PC-CV) is another fast charging protocol for LIBs, in which pulse current or pulse voltage is used to charge the batteries.
(2) Constant power discharge When the constant power discharges, the constant power power value P is set first, and the output voltage U of the battery is collected.
1) In the initial stage of the battery, the voltage drops rapidly, and the greater the discharge rate, the faster the voltage drops; 2) The battery voltage enters a slow change stage, which is called the platform area of the battery. The smaller the discharge rate,
