【Abstract】The performance level of low-voltage electrical systems directly affects the driving safety of road vehicles. This paper first analyzes common performance issues in low-voltage electrical systems and proposes corresponding test plans. Through research on existing domestic and international standards，applicability and benefit analysis，the necessity of establishing low-voltage electrical system performance requirements and testing methods standards has been established. Finally，a brief description is given of the content of the low-voltage electrical performance test standards.
