Research on the Starting-Time of Intelligent Recharge and Battery Self-Learning
When necessary,electric vehicles can charge the electric energy stored in the power battery into the lead-acid battery through the DC/DC,and the system to complete this function is called the intelligent recharge system.In this process,there exist power loss and the consumption of the number of charge and discharge cycles of the power battery and the lead-acid battery,so it is necessary to choose the right time to start the recharge,in order to reduce power loss and ensure the service life of the power battery and the lead-acid battery.By distinguishing whether DC/DC is working or not and whether lead-acid battery is self-learning or not,we summarized the starting time of recharge in different situations.When the battery does not complete self-learning,the battery charge state is corrected by detecting the battery charge state to complete the battery charge correction,so as to provide an accurate power quantity value for the intelligent recharge.
