Embodiment Construction
[0011] The vehicle static current testing system of the present invention will be described in detail below through specific embodiments.
[0012] see figure 1 , The vehicle quiescent current testing system of the present invention at least includes: a controlled unit, a standard resistor, a control unit, a data acquisition module, and a data conversion module.
[0013] The controlled unit is arranged in the vehicle to be tested, and one end is connected to the vehicle power supply through the fuse system of the vehicle to be tested, which can be a relay (ie, a signal relay).
[0014] One end of the standard resistor is connected to the other end of the relay, and the other end is connected to the vehicle electrical load (load after the system is dormant) of the vehicle to be tested. It can be seen that the power supply of the vehicle to be tested, The electric load of the whole vehicle, the controlled unit and the standard resistor form a series loop.
[0015] The control u...
