摘要
A kind of management system for electric vehicle (EV) battery series was developed. The system can predict residual capacity for EV battery series, determine if it is necessary for the battery series to be charged, determine which battery is necessary to be updated for the reason of damage or aging. The system can also display the total voltage of battery series, extreme voltage and temperature of every battery in the series, display the accumulative discharge for every battery in the series, and alarm when both total or extreme voltage is at low level, or temperature of a battery in the series is at high level. The system provided with a microprocessor as key part can collect and record signal of charging and discharging current, total voltage, extreme voltage and temperature for every battery. The mathematical model of residual capacity for EV lead-acid batteries was discussed in details. The system operates well in the laboratory and meets the requirement.
