Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries. The Voltage-Charge Relationship: Why It Matters. The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases.
As the battery pack is the heart of an EV, the on-board power systems that supply energy to the battery pack through charging piles, cables, and wiring harness, charging guns, and related components that help the EVs to get charged through the process of ''conduction'', becomes as important as the arteries and veins in the human body.
