The battery voltage chart is an essential tool for managing and using lithium ion batteries. It visually represents voltage variations during charging and discharging processes, with time as the horizontal axis and voltage as the vertical axis. By recording and analyzing this data, users can gain a better understanding of the battery's status and behavior, enabling them to take appropriate measures to enhance efficiency and reliability.
To ensure optimal performance, it is essential to charge the battery with a specific voltage and current; insufficient charging voltage will result in reduced capacity, while excessive charging voltage may damage the battery. Typically, a typical representation on a battery voltage chart shows that its voltage gradually decreases over time until depletion during discharge, increases until full capacity is reached, and then remains stable during charging.
Lithium-ion batteries include NCM lithium-ion batteries and LiFePO4 batteries; Below are their respective charge-discharge voltage charts.
