5Charging Control Technologies for Lithium-ion Batteries

5.1 Literature Review on Lithium-ion Battery Charging Technologies

The demand for lithium-ion batteries (LIBs) leads to a rapid growth in the related technologies. Lithium-ion batteries have a large capacity and have their own characteristics. The development of charging technologies is of great significance to relevant industries. The development of charging modes occurred in three stages: the charger-alone control mode, the BMS (battery management system)-cooperation control mode and the BMS-dominant control mode. There are also a variety of charging methods available now, including the current control method, the voltage control method, the Mas Law charging method and the modern intelligent charging method.

5.1.1 The Academic Significance of Charging Technologies of Lithium-ion Batteries

The development of the EV industry and the construction of charging infrastructure not only promote large-scale application of LIBs, but also pose higher requirements for the development of LIBs. Unlike lead-acid batteries, LIBs have strong technical advantages in terms of energy density, power density and cycle life. However, like lead-acid batteries, their level of resistance to abuse is currently undesirable, and their charging–discharging performance and cycle life can be greatly affected by the environment in which they are used. Thus, in order to improve the properties and manufacturing techniques of a battery, it is important to control ...
