System and method for establishing electric vehicle fully-automatic intelligent charging

Abstract

The invention belongs to the technical field of charging, and discloses a system and method for establishing electric vehicle fully-automatic intelligent charging. The system for establishing electricvehicle fully-automatic intelligent charging comprises a power module, an electric quantity detecting module, a temperature detecting module, a main control module, a charging induction module, a charging billing module, an alarm module and a display module. A target electric quantity value obtained by the electric quantity detecting module is closer to the charging and discharging law of a battery itself, can better reflect the essence of a battery parameter, and is more in line with the user experience; by adopting a target self-adaption correcting algorithm corresponding to a target electric quantity interval to determine the target electric quantity value, more accurate battery electric quantity value can be obtained without any additional hardware overhead and corresponding drive development cost; at the same time, through the charging billing module, more convenient charging methods and payment methods can be provided for a user, and the charging and payment can be completed smoothly without any extra action by the user.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a fully automatic intelligent charging system and method for establishing an electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. It uses electricity stored in the battery to start. Sometimes 12 or 24 batteries are used to power the car, sometimes more. The composition of electric vehicles includes: electric drive and control systems, mechanical systems such as drive force transmission, and working devices to complete established tasks. The electric drive and control system is the core of electric vehicles, and it is also the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a drive motor, a power supply, and a spee...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the electric vehicle full battery power detection is not accurate enough, which affects the charging judgment; at the same time, the existing charging billing is cumbersome; the temperature sensor generates a lot of noise in the process of collecting temperature, and the temperature signal is not Accurate; the fuel gauge detects the power inaccurately, which may easily cause overcharging or insufficient charging; the image display is not clear, the contrast is not high, and the noise is large
