Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
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 according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the system 100 may be applied to a vehicle 200, where the vehicle 200 includes a vehicle electrical appliance 201 and a starter 202, where the vehicle electrical appliance 201 includes a high-speed and low-speed fan, an instrument panel, a vehicle lamp, and the like (not shown in the figure), and the starter 202 is used for starting an engine (not shown in the figure).
The system 100 may include a high voltage power supply module 101, a controller 102, and a low voltage power supply module 103. The high-voltage power supply module 101 is connected with a whole vehicle electrical appliance 201 of the vehicle 200 to form a first power supply circuit; the low-voltage power supply module 103 is connected with a starter 202 of the vehicle to form a second power supply circuit; the first power supply circuit is connected to the second power supply circuit through the controller 102, and the controller 102 is configured to turn on or off the connection between the first power supply circuit and the second power supply circuit.
When the controller 102 conducts the connection between the first power supply circuit and the second power supply circuit, the high-voltage power supply module 101 and the low-voltage power supply module 103 jointly supply power to the electric appliance 201 and the starter 202 of the whole vehicle; when the controller 102 disconnects the first power supply circuit from the second power supply circuit, the high-voltage power supply module 101 supplies power to the electric appliance 201 for the whole vehicle, and the low-voltage power supply module 103 supplies power to the starter 202.
In one possible implementation, the controller 102 may be configured to disconnect the first power supply circuit and the second power supply circuit when receiving the start signal to the starter 202, so as to disconnect the power supply circuit of the low-voltage power supply module 103 for supplying power to the vehicle electrical appliance 201. The start signal may be a signal that is triggered when the vehicle receives a start request instruction to the engine.
In another embodiment of the present disclosure, the controller 102 may further detect an operating state of the high voltage power supply module 101, and when the operating state of the high voltage power supply module 101 is abnormal, the connection between the first power supply circuit and the second power supply circuit is turned on to turn on the power supply circuit that the low voltage power supply module 103 supplies power to the electrical apparatus 201 for the entire vehicle, and at this time, the low voltage power supply module 103 supplies power to the electrical apparatus 201 for the entire vehicle, so as to ensure that the electrical apparatus 201 for the entire vehicle can operate normally.
In another embodiment of the present disclosure, the controller 102 may further obtain a target power consumption of the electrical apparatus 201 for the entire vehicle, and when the target power consumption of the electrical apparatus 201 for the entire vehicle is greater than or equal to a first preset threshold, the power consumption requirement of the electrical apparatus 201 for the entire vehicle cannot be met only by the high-voltage power supply module 101, so that the controller 102 may switch on a connection between the first power supply circuit and the second power supply circuit to switch on the power supply circuit of the low-voltage power supply module 103 for supplying power to the electrical apparatus 201 for the entire vehicle. At this time, the high-voltage power supply module 101 and the low-voltage power supply module 103 jointly supply power to the electric appliance 201 for the entire vehicle, so as to meet the power consumption requirement of the electric appliance 201 for the entire vehicle.
In another embodiment of the present disclosure, as shown in fig. 2, the power supply system 100 may further include a power detection module 104. The electric quantity detection module 104 is connected to the controller 102 and the low-voltage power supply module 103, and can be used to obtain the remaining electric quantity of the low-voltage power supply module 103 in real time.
When the target power consumption is less than the first preset threshold, considering a situation that the low-voltage power supply module 103 needs to be charged when the remaining power amount is insufficient, correspondingly, if the obtained remaining power amount of the low-voltage power supply module 103 is greater than or equal to the second preset threshold, it can be considered that the low-voltage power supply module 103 does not need to be charged, and at this time, the controller 102 may disconnect the first power supply circuit and the second power supply circuit to disconnect the power supply circuit of the voltage power supply module 103 for supplying power to the electric appliance 201 of the entire vehicle and the power supply circuit of the high-voltage power supply module 101 for supplying power to the low-voltage power supply module 102. At the moment, the high-voltage power supply module 101 supplies power to the electric appliance 201 of the whole vehicle; if the acquired remaining power of the low-voltage power supply module 103 is less than the third preset threshold, it may be considered that the low-voltage power supply module 103 needs to be charged, and at this time, the controller 102 may conduct the connection between the first power supply circuit and the second power supply circuit to conduct the power supply circuit for the high-voltage power supply module 101 to supply power to the low-voltage power supply module 103. At this time, the high-voltage power supply module 101 supplies power to the electric appliance 201 of the whole vehicle, and the high-voltage power supply module 101 charges the low-voltage power supply module 103.
It should be noted that, in the power supply system shown in the above embodiments of the present disclosure, the low voltage power supply module 103 may be disposed at different positions of the vehicle, for example, may be disposed in an engine compartment, a luggage compartment, and a middle portion of a vehicle body (e.g., a middle portion of a driving cab) of the vehicle.
In the case where the low-voltage power supply module 103 is disposed in the middle of the trunk or the cockpit, since there is a risk of squeezing during a vehicle collision, a short circuit and fire may easily occur in the power supply circuit between the low-voltage power supply module 103 and the starter 202, and in order to avoid this problem, as shown in fig. 2, the power supply system 100 may further include a switch module 105. The switch module 105 is connected to an airbag controller (not shown in the figure), the low voltage power supply module 103 and the starter 202 of the vehicle, and is configured to disconnect a power supply circuit between the low voltage power supply module 103 and the starter 202 when receiving an indication signal indicating that the vehicle is in collision sent by the airbag controller. At this time, the high-voltage power supply module 101 and the low-voltage power supply module 103 can normally supply power to the electric appliance 201 for the entire vehicle, so as to ensure that the electric appliance 201 for the entire vehicle normally works, for example, a door of the vehicle can be normally unlocked, a TBOX can normally alarm, and the like.
In addition, in the case that the low voltage power supply module 103 is disposed in the middle of the vehicle body or in the luggage compartment, considering that the low voltage power supply module 103 needs to be connected across an external power supply when being fed, so as to ensure that the starter 202 can be started normally, as shown in fig. 2, the power supply system 100 may further include a cross-over start interface 106. The crossover start interface 106 is configured to conduct a power supply circuit between the switch module 105 and the starter 202, and the crossover start interface 106 is disposed within an engine compartment of the vehicle 200.
When the low-voltage power supply module 103 needs to be connected across the external power supply, the positive line of the external power supply can be connected to the cross-connection starting interface 106, and the negative line of the external power supply is grounded, so that power can be supplied to the starter 202, the starter 202 can normally start the engine, and further, a user does not need to open the middle part of the vehicle body or the luggage compartment of the vehicle 200 to find the low-voltage power supply module 103, and convenience is improved.
Fig. 3 and 4 are schematic structural views of a power supply system according to an exemplary embodiment of the present disclosure, in which the system 100 may be applied to a vehicle 200. As shown in fig. 3 and 4, in this embodiment, the system 100 includes a high voltage power supply module 101, a controller 102, a low voltage power supply module 103, a charge detection module 104, a switch module 105, and a jump starting interface 106.
The controller 102 may include a switch 121, one end of which is connected to the high voltage power supply module 101 and the vehicle electrical appliance 201, and the other end of which is connected to the low voltage power supply module 103 and the starter 202.
The low voltage power supply module 103 may include a low voltage power source 131 (e.g., a low voltage battery) that may be located at various locations on the vehicle as desired, such as in the engine compartment of the vehicle (as shown in fig. 3), or in the middle of the trunk or cockpit of the vehicle (as shown in fig. 4).
The high voltage power supply module 101 may include a high voltage power supply 111 (e.g., a high voltage battery) and a voltage conversion submodule 112, where the voltage conversion submodule 112 is connected to the high voltage power supply 111 and a vehicle electrical equipment 201 of the vehicle, respectively, and may be configured to convert an output voltage of the high voltage power supply 111 into a preset voltage and output the preset voltage to the vehicle electrical equipment 201. For example, the voltage conversion sub-module 112 may include a high-voltage DC-DC converter and a low-voltage DC-DC converter, wherein the high-voltage DC-DC converter may convert the output voltage of the high-voltage power supply 111 into a voltage of 12V and then output the voltage, and the low-voltage DC-DC converter may convert the voltage of 12V output by the high-voltage DC-DC converter into a voltage required by different devices in the electrical equipment of the entire vehicle again and then supply power to each device.
In order to protect the electric appliances for the entire vehicle, the high voltage power supply module 101 may further include a plurality of fuse boxes respectively connected to the electric appliances 201 for the entire vehicle. Illustratively, the high voltage power supply module 101 may include an engine fuse box (EJB)113 and an instrument beam fuse box (IPJB) 114. Further, as shown in fig. 4, in the case where the low voltage power supply module 103 is disposed in the middle of the trunk or cockpit of the vehicle, the high voltage power supply module 101 may further include a rear compartment fuse box (RJB)115 and a power distribution box 116 for distributing power, wherein the power distribution box 116 may be a primary fuse box connected to the controller 102, the engine fuse box (EJB)113, and the rear compartment fuse box (RJB)115, respectively.
The charge detection module 104 may include a battery sensor (IBS) 141.
The switch module 105 may include a crash disconnect Switch (SBK)151 controlled by an airbag controller (SDM), the crash disconnect switch 151 having one end connected to the low voltage power source 131 of the vehicle and the other end connected to the starter 202 through the jump starting interface 106. When a vehicle collides, after the controller 102 receives a collision signal sent by the airbag controller, the switch module 105 is powered off, so that a starter loop is protected from short circuit and fire, meanwhile, the switch 121 is connected with a power supply circuit between the low-voltage power supply 131 and the electric appliance 201 of the whole vehicle, so that other electric appliances of the whole vehicle are not powered off, the four doors of the vehicle can be normally unlocked, and the vehicle-mounted T-BOX can normally alarm.
In this embodiment, when the starter 202 of the vehicle is not required to be started, the switch 121 is in a closed state, the current output by the low-voltage power supply 131 flows to the electric appliances of the entire vehicle through each fuse box, the current output by the high-voltage power supply 111 flows to the electric appliances of the entire vehicle after sequentially passing through the voltage conversion sub-module 112 and each fuse box, and at this time, the high-voltage power supply 111 and the low-voltage power supply 131 jointly supply power to the electric appliances 201 of the entire vehicle.
In the starting process of the starter, when a starting signal to the starter is received, the trigger switch 121 is switched off, a power supply circuit between the low-voltage power supply 131 and the electric appliance 201 for the whole vehicle is switched off, the low-voltage power supply 131 supplies power to the starter, and current output by the high-voltage power supply 111 flows to the electric appliance 201 for the whole vehicle after sequentially passing through the voltage conversion submodule 112 and each fuse box to supply power to the electric appliance 201 for the whole vehicle.
When the voltage conversion submodule 112 is detected to be abnormal, the trigger switch 121 is turned on to conduct a power supply circuit between the low-voltage power supply 131 and the electric appliance 201 for the whole vehicle, and at this time, current output by the low-voltage power supply 131 flows to the starter to start the starter on one hand, and flows to the electric appliance 201 for the whole vehicle to supply power to the electric appliance 201 for the whole vehicle after passing through each fuse on the other hand, so that the electric appliance for the whole vehicle can normally work.
In addition, in the starting process of the starter, as shown in fig. 4, if the vehicle does not collide, the collision power-off Switch (SBK)151 is closed, at this time, the power supply circuit between the low-voltage power supply 131 and the starter 201 is turned on, and the starter can be started normally; if the vehicle collides, the collision Switch (SBK)151 is triggered to be turned off, at this time, the power supply circuit for supplying power to the starter 201 by the low-voltage power supply 131 is turned off, and the power supply circuit for supplying power to the electric appliance 201 for the entire vehicle by the high-voltage power supply 111 is turned on, so that the power supply circuit for the starter is prevented from being short-circuited and ignited due to vehicle collision while the normal operation of the electric appliance 201 for the entire vehicle is ensured.
In the power supply process of the electric appliance 201 for the whole vehicle, when the target electric quantity of the electric appliance 201 for the whole vehicle is detected to be greater than or equal to a first preset threshold value, the switch 121 is closed, the power supply circuit for supplying power to the electric appliance 201 for the whole vehicle by the low-voltage power supply 131 is conducted, and the low-voltage power supply 131 and the high-voltage power supply 111 jointly supply power to the electric appliance for the whole vehicle so as to meet the power consumption requirement of the electric appliance for the whole vehicle; when the target electric quantity of the electric appliance of the whole vehicle is detected to be smaller than a first preset threshold value, a storage battery sensor (IBS)141 can detect the residual electric quantity of the low-voltage power supply 131 in real time, if the obtained residual electric quantity is larger than or equal to a second preset threshold value, the switch 121 is switched off, at the moment, a power supply circuit for supplying power to the low-voltage power supply 131 by the high-voltage power supply 111 is switched off, and the low-voltage power supply 131 supplies power to the electric appliance of the whole vehicle; if the acquired remaining power is less than the second preset threshold, the switch 121 is closed, at this time, the power supply circuit for supplying power to the low-voltage power supply 131 by the high-voltage power supply 111 is turned on, and the high-voltage power supply 111 supplies power to the electric appliance 201 and the low-voltage power supply 131 of the entire vehicle at the same time.
