Problems solved by technology

This design and production method will cause the following problems: 1. Once the electric vehicle controller product is produced, its performance parameters and functions are fixed, and the performance or function cannot be modified or upgraded flexibly; 2. Due to the use of customized design and production 3. It is necessary to formulate a corresponding production process for each controller product, which makes the production process complicated and causes difficulties in maintenance
[0003] In this field, there is currently no external processor connected to the electric vehicle controller and then setting or adjusting the parameters of the electric vehicle controller through the communication circuit

Abstract

The invention belongs to a communication circuit for processing an electric vehicle controller. The invention provides a communication circuit of a programmer for an electric vehicle controller, which is practical, efficient, stable and reliable and can transfer a parameter signal better. In the invention, the technical problems are solved by adopting the following technical schemes that: the communication circuit of the programmer for the electric vehicle controller is arranged between a single chip which can realize the parameter regulation processing to the controller and the electric vehicle controller and used for transferring signal parameters, the communication circuit is a standard serial port communication circuit or a linear communication circuit, wherein one end of the communication circuit is connected with the single chip, and the other end of the communication circuit is connected with the electric vehicle controller by an external interface. The invention has the advantages of practical and reliable function, low cost as well as convenient and efficient use.

Description

technical field [0001] The invention belongs to a circuit applied to the field of electric vehicle control equipment, more specifically, a communication circuit for processing an electric vehicle controller. Background technique: [0002] Electric vehicles are favored by consumers for their lightness, speed, environmental protection, energy saving, and low price. The electric vehicle controller is one of the core components of the electric vehicle, and the electric vehicle usually completes the driving, turning, braking and other tasks of the electric vehicle under the control of the electric vehicle controller. At present, when manufacturers design and produce electric vehicle controllers, they usually design and produce electric vehicle controllers suitable for them according to the performance parameters and functional requirements of different electric vehicles. This design and production method will cause the following problems: 1. Once the electric vehicle controller ...
