Method for suppressing peak starting current of start-stop motor, relay and start-stop motor

Abstract

The invention discloses a method for inhibiting peak starting current of a start-stop motor. The method includes that firstly a relay with a current limiting resistor is added to a main start-stop motor loop comprising a storage battery, an ignition switch, a contact of an electromagnetic switch and the start-stop motor, and two binding posts of the current limiting resistor and the relay are parallelly connected and then connected between the ignition switch and the contact of the electromagnetic switch; and secondly, a power supply of the storage battery supplies power for coils of the relay and the electromagnetic switch respectively. The invention further discloses a relay for achieving the method for inhibiting peak starting current of the start-stop motor and a start-stop motor for implementing the method for inhibiting peak starting current of the start-stop motor. According to the method, the relay and the start-stop motor, the current limiting resistor is cut in or cut out when ignition is performed in the start-stop motor loop, so that overlarge starting current can be inhibited at the moment of starting of the start-stop motor so as to achieve the purpose of prolonging the service life of the start-stop motor.

Description

technical field [0001] The invention relates to a start-stop motor of an automobile, in particular to a method for suppressing the peak starting current of the start-stop motor. The invention also relates to a relay for realizing the above method and a start-stop motor for implementing the above method. Background technique [0002] The start-stop motor, also known as the start-stop motor, is used to start the engine of the car. At present, ordinary cars use starter motors (or called starters). Compared with ordinary starter motors, start-stop motors have a longer life and higher power. The start-stop motor comprises a motor and an electromagnetic switch, and the output shaft of the motor is connected with a start gear. After the ignition switch of the car is turned on, the battery of the car supplies power to the coil of the electromagnetic switch and the motor respectively, and the contacts of the electromagnetic switch are connected in series to the main circuit of the m...

Problems solved by technology

[0003] The power of the starter motor of the existing general car is still small, which cannot support the rapid start and stop of the car engine

However, if the power of the start-stop motor is increased to support quick start-stop, the instantaneous starting current when the start-stop motor starts will be further increased, and the starting current will have a large instantaneous peak value, which will shorten the life of the start-stop motor. It will also affect other electronic devices in the car (such as the ignition switch); if the number of starts and stops of the start-stop motor is reduced to prolong the life, the engine will often be in an idling state (such as when the car encounters a traffic light), thereby wasting gasoline resources. Increased exhaust emissions and noise, which is not conducive to environmental protection and energy saving
