Study on transition charging method of lithium-ion battery based on the multiple model adaptive control

For Traditional constant current/voltage charging method could cause temperature rise phenomenon with large current charging in later period, so this paper use transition charging method between constant current period and constant voltage period to adapt to the chemical reaction rate in the battery. And for the poor adaptability of general PI controller, this paper use multiple model adaptive control methods to improve the adaptability of controller and efficiency. It also ensure the accuracy and battery performance.
