Power supply system in vehicle and vehicle

Abstract

The invention relates to a power supply system in a vehicle and the vehicle. The system comprises a battery, a controller and a charging port; the controller is used for controlling the battery to supply power to the vehicle; the charging port is used for supplying power; and the controller and the charging port are connected in parallel and then are connected with the battery. The charging port is directly connected with the battery, so that the condition that current passes through the charging port all the time can be guaranteed. Thus, under the condition that the vehicle is not electrified, equipment can also be charged by the aid of the battery through the charging port, the vehicle is not required to be electrified to charge the equipment, the equipment can be charged more conveniently and quickly in the vehicle, additional electric energy consumed for electrifying of the vehicle is reduced, and potential safety hazards caused by parking in situ after electrifying of the whole vehicle are also reduced.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a system for supplying power in a vehicle and the vehicle. Background technique [0002] Vehicles usually have a charging interface that can charge devices such as mobile phones or tablet computers. The charging interface can be a USB interface that is directly connected to a charging cable, or it can be an interface that is inserted into an inverter in a cigarette lighter. No matter what kind of charging interface it is, it is necessary to charge the user's equipment when the vehicle is powered on. When the vehicle is not powered on, there is no power on the charging interface. When the vehicle is powered on, the entire vehicle circuit in the vehicle is in the conduction state, many relays in the circuit are also in the pull-in state, and many components that have nothing to do with the charging interface are also in working state, such as the instrument panel, etc. . Thi...

AI Technical Summary

Problems solved by technology

This will lead to excessive unnecessary power consumption during the charging process, and maintaining this state for a long time may cause the vehicle battery to run out of power, etc.

In addition, if the vehicle is powered on for the purpose of charging the equipment, and the vehicle is parked in place after the vehicle is powered on, it will bring a great potential safety hazard, because the vehicle will be in an unlocked position after the vehicle is powered on. state, so that there is a certain security threat to the people or objects in the car

Moreover, when the vehicle remains powered on, as long as any circuit connected to the charging interface is always in a state of current flow, this will waste a lot of power due to the consumption of the load in the circuit.
