Vehicle or machine starting circuit and vehicle or machine starting method

Abstract

The invention discloses a vehicle or machine starting circuit. In application, a controller can output a control signal that controls a transistor to be connected while controlling a controllable switch to remain disconnected, the control signal is transmitted to the transistor via electrical isolation equipment, the transistor is then connected, and under the action of current limiting resistance, capacitors in a main control electric circuit are slowly charged; after the capacitors are fully charged, the controller controls the controllable switch to be closed, the transistor and the currentlimiting resistance are in short circuit, and electricity supply of control electric circuit can be achieved by the controllable switch to meet electricity demand of loads. Therefore, instantaneouscurrent can be reduced when equipment with large capacitance such as a motor driver and a switching power supply are charged to improve electricity performance of the machine by applying the vehicle or machine starting circuit, increasing of the maximum discharge current of a battery or charging by groups is not needed, reliability of the machine can be guaranteed, and cost is lowered. In addition, the invention further discloses a vehicle or machine stating method which has the same effect as above mentioned.

Description

technical field [0001] The invention relates to the field of motors and electric control, in particular to a starting circuit and a starting circuit for a complete vehicle or a complete machine. Background technique [0002] With the development of science and technology, electric vehicles, mobile robots and other devices driven by electric energy are widely used. In order to prevent devices with large capacitors such as motor drivers and switching power supplies inside these devices from being out of control before the controller is initialized, the controller is generally powered on first, and after the controller is initialized, the motor is turned on through the control contactor. Power on devices with large capacitors such as drivers and switching power supplies. [0003] However, since each device such as the motor driver and switching power supply contains large capacitors, each capacitor is charged rapidly at the moment of power-on, and there will be an instantaneou...

Problems solved by technology

For the former, it will not only reduce the reliability of the whole machine, but also be limited by the performance of the battery. Under a certain battery capacity, the discharge current cannot be increased without an upper limit; Equipment with large capacitors such as power supplies are equipped with a contactor, which has high cost and poor economic benefits
