Auxiliary starting device and method for long-time shelving of automobile power supply

Abstract

The invention discloses an automobile power supply long-time shelving auxiliary starting device and method, and relates to the technical field of automobile power supplies. A vibration sensor is fixedly arranged on a negative electrode clamp, a control box is arranged on a negative electrode line, and a main processing controller and a switching circuit module are arranged in the control box; a current monitoring module, a vibration signal module, a delay module and a circuit control module are arranged in the main processing controller, the vibration signal module is in driving connection with the delay module, and the circuit control module is in driving control connection with the switching circuit module. The control box is arranged on the negative electrode circuit of the external power source, the vibration sensor is arranged on the negative electrode clamp, the starting state of the automobile is accurately judged, targeted secondary auxiliary starting is carried out after the automobile is not successfully started, meanwhile, the automatic disconnection type switching circuit module is designed, and the safety of the automobile is improved. Damage to the vehicle when the electrode clamp is disassembled in the process that the external power source assists in starting the vehicle and after starting succeeds is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile power supplies, in particular to an auxiliary starting device and method for long-time shelving of automobile power supplies. Background technique [0002] If the car is put on hold for a long time or uses electrical components for a long time after parking, the power of the car's starting battery may be greatly reduced. When the power of the starting battery is low, the car cannot start normally. This is because people can use the car power supply to assist the car starting battery to start the car. When using a car, many people want to start the car quickly, and do not want to fully charge the car starting battery. This is also because the car's own power generation will be slightly higher In terms of power consumption, as long as the car is started and the engine is not turned off, the car starting battery can gradually return to normal power. [0003] When performing a quick start, some pe...

Problems solved by technology

[0003] When performing a quick start, some people who do not understand the circuit or the principle of the car often connect the external power supply directly to the starting battery of the car. The remaining power of the external power supply itself or the incorrect voltage adjustment gear may not be able to provide It is a large peak current for the car to start, which makes the car battery unable to start normally

In addition, some people remove the electrode clip of the external power supply at will after starting the car successfully. If the positive electrode clip is removed first, it may cause damage to the single-wire electrical components in the car body to a certain extent.
