Abstract

The three-level structure composed of upper, median and lower machine is applied in battery test system (BTS) in this paper. The median machine in this BTS is designed and realized. CAN bus is used to communicate with each other between the upper and the median machine. RS-485 bus is used between the median and the lower machine. When the upper machine is online, the median machine can parse battery test instructions, store and send them to the lower machine. When the upper machine transits to offline state, the median machine can control the lower machine to continue battery test. When there is not an upper machine in BTS, the median machine can independently create and edit battery test and control the lower computer to complete test.
