Multistage constant current (MCC), pulse charging, boost charging, and variable current profiles (VCP) are among the fast charging methods used to reduce charging time without impacting battery life. Pulse charging uses high current pulses separated by short relaxation periods in an effort to minimize degradation.
The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and charger circuits for use with Nickel-Cadmium (Ni-Cd), Nickel Metal-Hydride (Ni-MH), and Lithium-Ion (Li-Ion) batteries.
Zuo et al. described fast charging strategies by framing the second-order RC model as a linear time-varying model predictive control problem and estimated the unmeasurable battery charge state and core temperature using a nonlinear observer. Building upon this foundation.
Each stage maintains a consistent charging current to expedite the charging speed. The primary concept of this strategy is to optimize the adjustment of the charging current and time allocation within each stage according to predefined charging time goals, with the ultimate aim of enhancing charging efficiency.
Fast charging is critical for the adoption of electric vehicles (EV’s), but higher current charging typically comes at the expense of battery life. Multistage constant current (MCC), pulse charging, boost charging, and variable current profiles (VCP) are among the fast charging methods used to reduce charging time without impacting battery life.
When establishing design standards based on charging time, it is crucial to consider the safety and reliability of batteries. Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery.
