Abstract

The invention provides a new energy automobile charging system control circuit which comprises a storage battery pack, the storage battery pack is connected with a DCDC direct-current power supply converter in parallel, and the DCDC direct-current power supply converter is connected with a key switch and a relay in series, wherein the DCDC direct-current power converter, the power main switch, therelay, the first fuse, the first diode and the low-voltage control system are sequentially connected in series, and the low-voltage control system is connected with the charging circuit in series. Reliable and stable charging requirements under the conditions that the power supply main switch is powered on, the key ON gear is powered on, the power supply main switch is powered on, the key ON gearis powered off, the power supply main switch is powered off and the key ON gear is powered off are met, that is to say, unattended charging and unattended charging can be achieved in the charging process; when charging is carried out on duty, a driver can turn on multimedia equipment to reduce waiting fatigue, and high-voltage and low-voltage electric appliances of the whole vehicle are powered by the charging equipment, so that the electric quantity of a battery is not consumed, and the battery is not damaged.

Description

technical field [0001] The invention relates to a new energy vehicle charging system control circuit and a control method, belonging to the field of new energy vehicles. Background technique [0002] As of 2018, the number of automobiles in my country has exceeded 200 million. Automobile pollution has become an important source of air pollution in my country and an important cause of air pollution. The urgency of reducing automobile pollution has become increasingly prominent. Energy security, energy conservation and emission reduction, and air pollution prevention and control are imminent. In this context, new energy vehicles are gradually introduced. [0003] The core technologies of new energy vehicles include power batteries, drive motors and electronic control systems. Among them, battery technology is the most important core technology of new energy vehicles, and charging technology is the basic key technology to ensure stable and reliable charging of batteries, ensu...
