Problems solved by technology

[0004] However, in the specific application of the above-mentioned charging device, each CAN bus can only communicate with one component of the car. When the charging device needs to communicate with multiple components, multiple CAN buses need to be set in the charging device. Satisfy the communication requirements between the charging device and the multiple components, resulting in an increase in the cost of the charging device and a reduction in the reliability of communication between the charging device and the multiple components

Embodiment Construction

[0020] At present, although multiple CAN buses can be set in the internal setting of the charging device, the charging device can only communicate with one external component through each CAN bus, which not only increases the cost of the charging device, but also causes communication between the charging device and external components. reduced reliability.

[0021] In view of the above problems, an embodiment of the present invention provides a charging device, wherein more than two switches can be set on one CAN bus of the charging device. In this way, under the control of the controller, only one CAN bus can be used to communicate with more than two external components, which can effectively reduce the number of CAN buses inside the charging device, thereby reducing the cost of the charging device and improving Reliability of communication between the charging unit and external components.

[0022] In order to make the above objects, features and advantages of the present i...

Abstract

A charging device and its communication system. The charging device includes: a controller; a voltage regulator suitable for providing a stable voltage to the controller; a voltage converter connected to the voltage regulator; CAN transceiver; and two or more switches arranged on the CAN bus and connected to the CAN transceiver; the charging device is controlled by the controller, through the two or more switches respectively communicate with the corresponding external components. The application of the charging device can not only reduce the cost of the charging device, but also improve the reliability of communication between the charging device and other parts of the car.

Description

technical field [0001] The invention relates to the field of automobile charging, in particular to a charging device and a communication system thereof. Background technique [0002] Control Area Network (CAN) is a field bus that supports distributed control or real-time control, and has the characteristics of high performance and high reliability. [0003] With the development of modern automobile technology, the application of CAN technology in automobile network is becoming more and more extensive, especially in the field of automobile charging. For example, in a charging device used to charge a battery system of an automobile, multiple CAN buses are usually provided to meet the communication requirements between the charging device and other components. The above-mentioned other components may include diagnostic tools for diagnosing the charging device, or components such as the battery system of the vehicle. [0004] However, in the specific application of the above-m...
