汽车电气系统电流匹配计算与验证

摘要

In order to test electric charge is matching the electrical system or not, the paper calculates and testifies the current matching for the vehicle electrical system with the mettlod of calculating and measuring output current of motor can satisfy the necessary current of vehicle device. The calculation results show that the vehicle can meet the current matching for electrical system. By measuring output current of motor and the necessary current for vehicle device, the result is verified to be correct. Due to the 22 ~C temperature of the testing environment, it is suggested that another test is needed to be conducted in a higher temperature in the future.%为验证汽车电气系统电荷是否匹配，文章以某款轿车为例，用计算及测量发电机输出电流是否能满足车内用电设备所需要的电流的方法，对该车的电气系统进行电流匹配的计算与验证。计算结果表明该轿车满足汽车电气系统电流匹配的要求。通过测量发电机输出电流及车内用电设备所需要的电流，验证了理论计算所得结果的准确性，由于测试环境温度不高（22℃左右），建议今后在高温条件下再次进行实车验证。
