CONTROL STRATEGY FOR HV BATTERY EQUALIZATION CHARGE DURING DRIVING OPERATION IN FUEL CELL HYBRID VEHICLES |
摘要 |
A system and method for equalizing the state of charge of the cells of a battery in an electric vehicle while the vehicle is being driven. The method includes monitoring the state of charge of the battery cells in the battery and measuring the actual current of the battery. The method also includes determining a maximum charge current limit of the battery and comparing the actual battery current and the charge current limit. The method also includes modifying the charge current limit based on the comparison between the actual battery current and the charge current limit. The method then converts the modified charge current limit to a power charge limit and then over charges the battery using a small amount of current and the power charge limit so that all of the cells in the battery become fully charged.
