Emergency standby power supply system of new energy automobile

Abstract

The invention discloses an emergency standby power supply system of a new energy automobile. The system comprises an emergency lifesaving system, the emergency lifesaving system comprises a monitoringmodule, a charging module, an original vehicle power supply module, an emergency power supply module, a control module and a bidirectional circuit module, the emergency lifesaving system is applied to an electronic vehicle door lock working circuit of an original vehicle. An electronic vehicle door lock is in control connection with the original vehicle power supply module and the emergency powersupply module through the bidirectional circuit module. The monitoring module performs information interaction for monitoring the abnormal function of the power supply with the original vehicle powersupply module and the emergency power supply module; the control module and the monitoring module carry out information interaction of monitoring data, the control module sends a control instructionto implement a circuit switching function of the bidirectional circuit module, and the monitoring module and the charging module carry out information interaction while the charging module is electrically connected with the original vehicle power supply module and the emergency power supply module. When a vehicle falls into a river due to a traffic accident, people in the vehicle can escape more conveniently, and the guarantee degree of life safety is improved.

Description

technical field [0001] The invention mainly relates to the technical field of new energy vehicle emergency, in particular to a new energy vehicle emergency backup power supply system. Background technique [0002] In recent years, the development of new energy vehicles has been very rapid, which has reduced the exhaust pollution caused by fuel vehicles. However, the common problem of new energy vehicles is that they cannot touch water, especially when a vehicle falls into a river due to a traffic accident. The power supply will quickly fail. At this time, the electronic lock of the car door cannot be opened after the original car power supply is disconnected, and the people in the car are too late to open the car door in a panic, which poses a great threat to life. [0003] According to the existing new energy models, the monitoring and unlocking control of the door locks are all controlled by the original vehicle control system. Once the original vehicle power supply fails,...

[0002] In recent years, the development of new energy vehicles has been very rapid, which has reduced the exhaust pollution caused by fuel vehicles. However, the common problem of new energy vehicles is that they cannot touch water, especially when a vehicle falls into a river due to a traffic accident. The power supply will fail quickly. At this time, the electronic lock of the car door cannot be opened after the original car power supply is disconnected, and the people in the car are too late to open the car door in a panic, which poses a great threat to life.

[0003] According to the existing new energy models, the monitoring and unlocking control of the door locks are all controlled by the original vehicle control system. Once the original vehicle power supply fails, the circuit of the whole vehicle will not work, so that in the event of a car accident that falls into the river Increased rescue difficulty
