Abstract

The invention discloses a method for simulating a vehicle starting power supply. The method comprises the steps that S1, a direct-current power supply, a control module and a to-be-tested device are electrically connected in sequence to form a loop; S2, a first relay and a second relay are connected between the control module and the to-be-tested device, and the first relay and the second relay are connected in parallel; S3, the first relay and the second relay are circularly opened and closed at different frequencies; and S4, the control module monitors the first relay, the second relay and the to-be-tested device. According to the method for simulating a vehicle starting power supply disclosed by the invention, the bench test power supply achieves the effect of vehicle power supply jitter through simple operation of assessing the relays into the circuit, so that some problems caused by power supply jitter of a vehicle-mounted product on a real vehicle can be discovered in time.

Description
