At a time when the wave of technology is sweeping the world, lithium batteries have long become the "energy code" that changes life! From mobile phones at your fingertips to electric cars, from giant energy storage power stations to precision aviation equipment, lithium batteries are everywhere, injecting surging power into modern life. ​

Lithium batteries are like "chemical elevators". Lithium ions shuttle between the positive electrode (lithium iron phosphate/ternary lithium) and the negative electrode (graphite), and electrons form current power supply through external circuits. Ternary lithium batteries have high energy density (Tesla Model S 21700 battery cells reach 333Wh/kg), which is suitable for long-range electric vehicles; lithium iron phosphate batteries are safe and durable (BYD blade batteries have more than 2,000 cycles). It is recommended to keep the power at 30%-80% on a daily basis, and shallow charging and shallow discharge can prolong life.

At the moment when new energy vehicles are popular, the accuracy of battery life directly affects the user's travel experience. As the use time increases, the battery management system (BMS) may deviate from the calculation of power, resulting in the display of battery life and actual battery life not matching. At this time, it is particularly important to calibrate the battery charge. Below, we will introduce the fast charging calibration steps and precautions for lithium iron phosphate batteries and ternary lithium batteries in detail to help you regain accurate battery life. ​
