In the present disclosure, the terms "first," "second," and the like in the description and claims of the present disclosure and in the drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Fig. 1 is a block diagram illustrating a power supply system applicable to a vehicle according to an exemplary embodiment of the present disclosure, and the system 100 may include a low voltage power source 101, a switching module 102, and a starter 103, wherein the switching module 102 is connected to the low voltage power source 101 and the starter 103, respectively, and the starter 103 is used to start an engine of the vehicle.
Under normal conditions, a power supply circuit between the low-voltage power supply 101 and the starter 103 is in a conducting state, when an engine of a vehicle needs to be started, the low-voltage power supply 101 can supply power to the starter 103 to drive the engine to work, and when the vehicle collides, the switch module 102 responds to a received indication signal indicating that the vehicle collides to disconnect the power supply circuit between the low-voltage power supply 101 and the starter 103, so that the phenomenon that a circuit between the low-voltage power supply 101 and the starter 103 is short-circuited and ignited due to extrusion when the vehicle collides is avoided, and the effect of protecting the vehicle is achieved. The indication signal may be generated and sent to the switch module 102 by an air bag controller (SDM) of the vehicle when detecting a collision of the vehicle.
Alternatively, as shown in fig. 2, the low voltage power source 101 may be a 12V low voltage battery and the switch module 102 may be a crash disconnect switch 121 (e.g., SBK switch). When the vehicle collides, the collision cutoff switch 121 cuts off the power supply when receiving the indication signal indicating that the vehicle collides, and cuts off the power supply circuit between the low-voltage battery and the starter 103 to protect the power supply circuit between the low-voltage battery and the starter 103.
In another embodiment of the present disclosure, as shown in fig. 2, the system 100 further comprises a first controller 104. The first controller 104 is connected to the switch module 102 and is configured to send an indication signal indicating that the vehicle has collided to the switch module 102 when the vehicle has been detected to have collided. Accordingly, after receiving the indication signal, the switch module 102 may disconnect the power supply circuit between the low voltage power supply 101 and the starter 103, so that a short circuit and fire may be prevented from occurring in the circuit between the low voltage power supply 101 and the starter 103 due to being extruded when the vehicle collides, and the vehicle may be protected.
Alternatively, the first controller 104 may include an airbag controller (SDM)141, and the airbag controller 141 is connected to the switch module 102, and when the vehicle collides, the airbag is ejected, and the airbag controller 141 is triggered to send an indication signal indicating the collision of the vehicle to the switch module 102.
It is noted that, for the power supply system according to the embodiment of the present disclosure, the low-voltage power source 101 may be disposed in a middle portion of a vehicle body (e.g., a middle portion of a cockpit) or a trunk room of the vehicle. In this case, the power supply system 100 may further include a crossover start interface 105 disposed between the switch module 102 and the starter 103, wherein the crossover start interface 105 is configured to conduct a power supply circuit between the switch module 102 and the starter 103 and the crossover start interface 105 is disposed in an engine compartment of the vehicle. In addition, the jump starting interface 105 may be used to connect to an external power source (not shown) to conduct a power supply circuit for supplying power to the starter 103. Specifically, the positive line of the external power source may be connected to the jump starting interface 105 and the negative line of the external power source may be grounded. Therefore, when the electric quantity of the low-voltage power supply 101 is not enough to start the starter 103, the external power supply can supply power to the starter 103, so that the starter 103 can work normally to start the engine, a user does not need to open the middle part of a cab or a luggage compartment to search for the low-voltage power supply 101, and convenience in bridging starting is improved.

In another embodiment of the present disclosure, the power supply system 100 further includes a power detection module 110 and a second controller 111, wherein the power detection module 110 is connected to the low voltage power source 101 for obtaining the remaining power of the low voltage power source 101. The second controller 111 is connected to the power detection module 110 and the generator 107, and is configured to control the generator 107 to operate when the remaining power of the low-voltage power source 101 is less than or equal to a first preset threshold, so that the generator 107 charges the low-voltage power source 101.
