Compared with the current vehicle battery fuel vehicles are still many aspects, such as cost, quality, long charging time and charging time shorter mileage and other issues. This design introduces the development history and status quo of electric vehicles and the basic performance indexes of the on-board battery and designed a complete set of on-board battery intelligent discharge management system based on P87C591 microcontroller . Including Power circuit design Current and voltage detection circuit design, the design of the temperature detection module, Design of controllable discharge module, The output power and status indication and alarm module design and so on hardware structure design. Completed the lead-acid storage battery voltage, discharge current, residual capacity and the battery temperature, and other important parameters of detection .Solved the traditional way of discharge of battery over discharge, low life .To achieve the mileage and maximize the range of electric cars and life cycle, has the very good application prospect.
