Abstract

The invention discloses a CAN bus-Ethernet data conversion device for battery testing. The CAN bus-Ethernet data conversion device comprises a bidirectional conversion device, and a power supply, an Ethernet interface and a CAN card which are connected with the bidirectional conversion device, the bidirectional conversion device is composed of a communication parameter configuration module, a CAN data analysis module, a CAN data receiving and transmitting module, a data mapping and packaging module and a UDP data receiving and transmitting module, the number of the CAN cards is multiple, the CAN cards are connected with the bidirectional conversion device through a PCI bus or a USB bus, and the CAN cards are connected with the CAN communication aviation plug. The invention further discloses a data bidirectional conversion method. According to the invention, continuously increasing and changing CAN acquisition and control equipment data processing requirements of customers can be met, so that the flexible expansibility of power battery charging and discharging test equipment software is greatly improved, and a large number of development and hardware costs of such integrated design are reduced.

Description

technical field [0001] The invention belongs to the technical field of power battery charging and discharging testing, and in particular relates to a multi-channel CAN bus and Ethernet data bidirectional conversion device in battery testing and a data bidirectional conversion method thereof. Background technique [0002] During the power battery charge and discharge test process, the charge and discharge test equipment often needs to communicate with the battery management system (BMS, BMU) and other third-party acquisition or control equipment, such as figure 1 As shown, most of these devices, especially those related to power batteries and new energy vehicle companies, use CAN communication to send and receive data. There are many devices with inconsistent baud rates, so it is difficult to integrate into a CAN network. [0003] The general solution is to expand the CAN port on the bottom control circuit board side in the charge and discharge test equipment, but because the...
