And under the condition that the at least one second switch piece is in a conducting state, the at least one first switch piece correspondingly arranged by the at least one second switch piece is in a disconnecting state.
The first power supply circuit can be used as a main power supply circuit, the second power supply circuit can be used as a redundant power supply circuit, and the first power supply circuit and the second power supply circuit can be respectively and electrically connected with a power port of a specific power supply, so that electric energy output by the specific power supply can be transmitted to first electric equipment through the first power supply circuit or the second power supply circuit to realize power supply for the first electric equipment. For example, when the power supply and distribution system is applied to a vehicle, the above-described specific power source may be a power battery in the vehicle, and the first power supply circuit and the second power supply circuit may be electrically connected to power supply ports in the vehicle, that is, output ports of the power battery in the vehicle, respectively. Therefore, the first power supply circuit or the second power supply circuit can be used for establishing electric connection between the power battery and the first electric equipment so as to supply power to the first electric equipment. Hereinafter, taking the power supply and distribution system as an example of the power supply and distribution system in a vehicle, the power supply and distribution system provided by the present disclosure is further explained as follows:
Among the at least one first electric device, different first electric devices are also different electric devices in the vehicle. And the first electric equipment can be key electric equipment in the vehicle, for example, electric equipment in a braking system, electric equipment in a steering system and the like. Therefore, the two power supply circuits are adopted to supply power to the first electric equipment, redundant power supply to key equipment in the vehicle is facilitated, and the stability of power supply to the key equipment in the vehicle is ensured.
The first switch element and the second switch element may be various switch elements in the related art, for example, may be MOS transistors, switch chips, and the like. The number of the first switch pieces in the distribution box is the same as the number of the first electric equipment, and the number of the second switch pieces in the distribution box is the same as the number of the first electric equipment. The at least one first switch piece corresponds to the at least one first electric equipment one by one; the at least one second switch piece corresponds to the at least one first electric equipment one by one.
The main power supply control chip is electrically connected with the second switch piece corresponding to the first switch piece, and specifically comprises: the main power supply control chip is electrically connected with each second switch in the at least one second switch piece respectively.
When a first switch piece corresponding to a certain first electric equipment is in a conducting state, the first electric equipment is conducted with the output end of the first power supply circuit, and at the moment, power can be supplied to the first electric equipment based on the first power supply circuit. Correspondingly, when a first switch piece corresponding to a certain first electric equipment is in an off state, the first electric equipment is disconnected from the output end of the first power supply circuit, and at the moment, power cannot be supplied to the first electric equipment based on the first power supply circuit. When a second switch piece corresponding to a certain first electric equipment is in a conducting state, the first electric equipment is conducted with the output end of the second power supply circuit, and at the moment, power can be supplied to the first electric equipment based on the second power supply circuit. Correspondingly, when a second switch piece corresponding to a certain first electric equipment is in an off state, the first electric equipment is disconnected from the output end of the second power supply circuit, and at the moment, power cannot be supplied to the first electric equipment based on the second power supply circuit.
It is understood that, in order to avoid that the first power supply circuit and the second power supply circuit supply power to the first electric equipment at the same time, the main power supply control chip may control the at least one second switch element to be turned off under the condition that the at least one first switch element is controlled to be turned on. And simultaneously, under the condition that the at least one second switch piece is controlled to be conducted, the at least one first switch piece is controlled to be disconnected. In addition, when the power supply and distribution system is in a non-power supply state, the main power supply control chip may control the at least one first switching element to be turned off, and control the at least one second switching element to be turned off.
The main power supply control chip may be various control chips in the related art, for example, various microcontrollers.
The voltage comparator may be a voltage comparator in the related art, and the voltage comparator may compare voltages of the first input terminal and the second input terminal, and characterize a comparison result by outputting a high level or a low level, for example, in a case that an output voltage of the first power supply circuit is higher than or equal to an output voltage of the second power supply circuit, an output terminal of the voltage comparator may send a high level to the main power supply control chip; and under the condition that the output voltage of the first power supply circuit is lower than the output voltage of the second power supply circuit, the output end of the voltage comparator can send a low level to the main power supply control chip so that the main power supply control chip can determine the relative magnitude between the output voltage of the first power supply circuit and the output voltage of the second power supply circuit.
It can be understood that the main power supply control chip selects the first power supply circuit or the second power supply circuit to supply power to the first electric equipment in the working state according to the output result of the voltage comparator only when the first electric equipment is in the working state. When the first electric equipment is in a non-working state, the first switch piece and the second switch piece corresponding to the first electric equipment are in an off state.
Specifically, the voltage comparator is used for comparing the relative magnitudes of the voltages output by the first power supply circuit and the second power supply circuit and transmitting the comparison result to the main power supply control chip, so that the main power supply control chip can control the conduction states of the first switch piece and the second switch piece according to the comparison result, and one of the first power supply circuit and the second power supply circuit is selected to supply power to the first electric equipment.
In this embodiment, since the main power supply control chip can control the on states of the first switch element and the second switch element, the main power supply control chip can control the on states of the first switch element and the second switch element to select one of the first power supply circuit and the second power supply circuit to supply power to the first electric equipment, so that the two power supply circuits are adopted to supply power to the first electric equipment, redundant power supply to the first electric equipment is facilitated, and the stability of the power supply and distribution system for supplying power to the first electric equipment is ensured.
Optionally, in a case where the power supply and distribution system is in a power supply state and an output voltage of the first power supply circuit is higher than an output voltage of the second power supply circuit, each of the at least one first switching element is in a conductive state and each of the at least one second switching element is in an off state;
In the case that the power supply and distribution system is in a power supply state and the output voltage of the first power supply circuit is lower than the output voltage of the second power supply circuit, each of the at least one first switching element is in an off state and each of the at least one second switching element is in an on state.
The power supply and distribution system being in a power supply state may specifically mean that the first electric equipment is in a working state. Correspondingly, when the power supply and distribution system is in a non-power supply state, the first electric equipment is in a non-working state.
When the power supply circuit is abnormal, the output voltage of the power supply circuit is usually reduced to a smaller value, and at the moment, the abnormal power supply circuit cannot normally supply power to the electric equipment. Based on this, in the embodiment of the disclosure, by electrically connecting the output end of the first power supply circuit with the first input end of the voltage comparator, the output end of the second power supply circuit is electrically connected with the second input end of the voltage comparator, so that the voltage comparator can detect and compare the relative magnitude of the output voltage between the first power supply circuit and the second power supply circuit, and feed back the comparison result to the main power supply control chip, and the main power supply control chip can select the power supply circuit with higher output voltage to supply power to the first power consumption device according to the comparison result, so as to ensure the stability of power supply to the first power consumption device.

Correspondingly, under the condition that the output voltage of the first power supply circuit is lower than the output voltage of the second power supply circuit, the output end of the voltage comparator can send a low level to the main power supply control chip, and the main power supply control chip can control each first switch piece in the at least one first switch piece to be disconnected and control each second switch piece in the at least one second switch piece to be conducted under the condition that the voltage is lower than the low level sent by a machine, and at the moment, power is supplied to the at least one first electric equipment based on the second power supply circuit.
In other embodiments of the present disclosure, when the output voltage of the first power supply circuit is higher than the output voltage of the second power supply circuit, the output terminal of the voltage comparator may send a high level to the main power supply control chip, and the main power supply control chip may control each first switch of the at least one first switch to be turned on and control each second switch of the at least one second switch to be turned off when receiving the high level sent by the machine, and power the at least one first powered device based on the first power supply circuit.

In the embodiment, the main power supply control chip is used for selecting the higher output voltage of the first power supply circuit and the second power supply circuit as the power supply of the first electric equipment based on the comparison result of the output voltage of the first power supply circuit and the output voltage of the second power supply circuit by the voltage comparator, so that the stability of power supply to key equipment in the vehicle is guaranteed, and the power supply effect to the vehicle is improved.

Specifically, when a third switch piece corresponding to a certain second electric equipment is in a conducting state, the second electric equipment is conducted with the output end of the first power supply circuit, and at the moment, power can be supplied to the second electric equipment based on the first power supply circuit. Correspondingly, when a third switch piece corresponding to a certain second electric equipment is in an off state, the second electric equipment is disconnected from the output end of the first power supply circuit, and at the moment, power cannot be supplied to the second electric equipment based on the first power supply circuit.
The second electric equipment can be non-critical electric equipment. For example, when the power supply and distribution system is applied to a vehicle, the second power consumption device and the first power consumption device are different power consumption devices in the vehicle, and the different second power consumption devices are also different power consumption devices in the vehicle. The second powered device may be a non-critical powered device in the vehicle, for example, a vehicle light, a seat heating device, etc.
