How are Li-ion batteries charged?

Li-ion batteries are typically charged in two main phases: the Constant Current (CC) phase and the Constant Voltage (CV) phase. Proper management of voltage, current, and temperature is crucial to prevent issues that can result in thermal runaway, which can for example lead to overheating, fire, toxic gas production, or explosions. Effective battery management systems (BMS) monitor these parameters to ensure safe and efficient charging. This article was published on the webpage of the CPD.
