A method for auxiliary starting of an engine

Abstract

The invention provides an auxiliary starting device and method for an engine and relates to the field of engine power sources. The auxiliary starting device comprises an MCU controller, super-capacitors, a first output end Clip-P and a second output end Clip-N. A first signal receiving end U1 of the MCU controller is connected with the first output end Clip-P. One ends of the super-capacitors are connected with the first output end Clip-P through an ignition control relay K2, and the other ends of the super-capacitors are connected with the ground. The ignition control relay K2 is connected to a second control end SW2 of the MCU controller in a controlled mode, a voltage equalizing circuit is arranged on each super-capacitor, and the MCU controller is further connected with a remote control terminal. According to the auxiliary starting device and method for the engine, voltage needed for engine starting is provided through the super-capacitors, and charge and discharge of the super-capacitors can reach hundred of hundreds of thousands of times; the voltage equalizing circuits are arranged on the super-capacitors and used for equalizing the voltage of the super-capacitors to enable the service life of the super-capacitors to be longer, so that the overall service life is further prolonged. In addition, the remote control terminal is further arranged so that the remote control function can be implemented.

Description

technical field [0001] The invention relates to the field of engine power supplies, and specifically discloses an engine auxiliary starting method. Background technique [0002] The starting system of a car is composed of a battery, an ignition switch, a starting relay, a starter, etc. It mainly converts the electric energy of the battery into mechanical energy to start the engine. Almost all car engines require an electric starting system. The starting voltage of the car engine is about 12V, and the output voltage of the car battery is generally 13V-15V. When the battery is discharged at a high rate or low temperature, the performance will become very poor, resulting in the output voltage not meeting the requirements for starting the engine. [0003] In order to deal with the situation that the car battery cannot start the engine, the existing technology uses an auxiliary starting device with built-in batteries such as lead-acid batteries or lithium batteries. engine.

AI Technical Summary

Problems solved by technology

However, the lead-acid battery is bulky and requires a special charger for maintenance and maintenance; the use of lithium batteries can solve the problem of bulky lead-acid batteries and maintenance, but the high-rate discharge characteristics of this type of power lithium battery are likely to cause battery failure, or even Fired and scrapped, there are safety issues

Usually the life of the battery is 2-3 years, but in actual use, due to ignorance of regular maintenance, the life of the auxiliary starting device cannot reach 2-3 years, and even some users have not used the device, and its life has expired, resulting in extreme big waste of resources

[0004] The existing auxiliary starting devices usually have the following defects: regular maintenance is required, there are safety hazards, the life is short, the charging time is too long, and a special charger is required for charging
