Charging up a battery is the exact opposite of discharging it: where discharging gives out energy, charging takes energy in and stores it by resetting the battery chemicals to how they were originally.
The key to EVs is their power batteries, which undergo a complex yet crucial charging and discharging process. Understanding these processes is crucial to grasping how EVs efficiently store and use electrical energy. This article will explore the intricate workings of the charging and discharging processes that drive the electric revolution.

Batteries, Battery Management, and Battery Charging Technology. Figure 32 Bidirectional configuration for BESS In the case of PHEVs, the battery pack should have this capability to store energy from an external power source and regenerative braking as well as sending back the stored energy to the utility grid.
Large duty cycles are applied during the initial stages of charging to ensure fast charging. After battery voltage is increased sufficiently, the duty cycle gradually decreases to prevent overcharging and consequent battery failure.

CV (Constant Voltage Charging) The constant voltage (CV) threshold for lithium batteries is typically 4.1v to 4.5v per cell. The charging IC monitors the battery voltage during constant current charging. Once the battery reaches the constant voltage charging threshold, the charger IC transitions from constant-current to constant-voltage regulation.
