Embodiment 1
[0039] Please refer to figure 1 , this embodiment proposes a power management system for preventing vehicle power feeding, which includes a PS controller, an ACC relay, an IG1 relay, an IG2 relay and a storage battery;
[0040] exist figure 1 Among them, B+ refers to the positive pole of the battery.
[0041] Specifically, a timer is provided in the PS controller; the timer is used for timing.
[0042] The PS controller is electrically connected to the storage battery to realize power supply through the storage battery; and the output terminals of the PS controller are respectively connected to the coil connection pins of the ACC relay and the coil connection pins of the IG1 relay . The coil connection pins of the IG2 relay are electrically connected to control the on-off of the ACC relay, the IG1 relay and the IG2 relay;
[0043] The switch pin of the ACC relay, the switch pin of the IG1 relay and the switch pin of the IG2 are connected in series between the corresponding ...
Embodiment 2
[0055] Please refer to figure 2 , this embodiment proposes a battery management method for preventing vehicle power feeding, which is used in the battery management system for preventing vehicle power feeding as described in any one of the above items.
[0056] Including the following steps:
[0057] S1, when the vehicle is parked, monitor whether the vehicle is at rest; if yes, go to step S2; if not, repeat this step;
[0058] S2, start timing; and obtain the status signal of the air conditioner blower, the status signal of the ambient light and the status signal of the sound;
[0059] S3. If at least one of the air conditioner blower status signal, the ambient light status signal and the audio status signal is on after the first set time is exceeded, and none of the signals jumps, cut off the corresponding controller and electrical appliances, and only Keep the normal power supply connected; if each signal jumps within the first set time, maintain the current working stat...

Abstract
The invention discloses a power supply managementsystem and method for preventing vehicle feed, and the system comprises a PS controller, an ACC relay, an IG1 relay, an IG2 relay, and a storage battery. A timer is arranged in the PS controller; the PS controller is electrically connected with the storage battery so as to realize power supply through the storage battery; the output end of the PS controller is electrically connected with a coil connecting pin of the ACC relay, a coil connecting pin of the IG1 relay and a coil connecting pin of the IG2 relay so as to control on-off of the ACC relay, the IG1 relay and the IG2 relay. The switch pin of the ACC relay, the switch pin of the IG1 relay and the switch pin of the IG2 relay are connected in series between the corresponding vehicle-mounted power utilization unit and the storage battery; and the PS controller is connected with a CAN bus. The feed problem caused by abnormal use can be prevented.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a power managementsystem and method for preventing vehicle power feeding. Background technique [0002] At present, the electrical configurations on automobiles are becoming more and more abundant, and the number of automobile controllers and electrical appliances is increasing. Various safety configurations and comfort configurations will still work after the engine is stopped, and continue to consume battery power, especially when the vehicle is not in a timely and normal state. When the power is off, it causes the vehicle to feed power, which in turn poses a start-up risk. When tracking the cause of the failure of vehicles in a certain model market, it is found that 33% of the failures are caused by customers not turning off the power in time after using the car, forgetting to lock the car or continuing to use electrical appliances for a long time after stopping, and corr...
