METHOD, DEVICE, SYSTEM FOR ESTIMATING REMAINING CHARGING TIME AND STORAGE MEDIUM

The present disclosure discloses a method, a device, a system, and a storage medium for estimating remaining charging time. The method includes: determining a charging requested current value and a battery temperature change rate; estimating a first estimated time required for the battery to be charged from the state of charge estimation initial value to an upper limit of the state of charge estimation section; estimating a second estimated time required for the battery to be changed in temperature from the temperature estimation initial value to an upper limit of the temperature estimation section; determining a new state of charge estimation initial value, a new state of charge estimation section, and a new temperature estimation initial value and a new temperature estimation section based on a smaller estimated time between the first estimated time and the second estimated time, until an upper limit of an state of charge estimation section reaches a target state of charge and a smaller estimated time is a first estimated time; and accumulating every determined smaller estimated times to obtain an estimated remaining charging time for the battery to be charged to the target state of charge. According to the method in embodiments of the present disclosure, accuracy of estimation of remaining charging time can be improved.
