Embodiment
[0031] The electric vehicle DC charging module controller program online upgrade system is mainly used for the online upgrading of the electric vehicle DC charging module controller (referred to as "controller") program, such as figure 1 As shown, it includes several controllers to be upgraded, the Ethernet chip on the controller, and the host computer installed with TCPIP data transmission software;
[0032] The electric vehicle DC charging module controller includes a DSP chip as a central control unit, a FLASH chip as an external program memory, an EEPROM memory chip as an internal data memory, and an Ethernet chip for realizing Ethernet communication functions;
[0033] Among them: the DSP chip is connected to the FLASH memory chip through the data and address bus to realize the storage and calling of the program firmware; the DSP chip is connected to the EEPROM memory chip through the I2C bus; the DSP chip is connected to the Ethernet chip through the SPI bus, and the uppe...

The present invention discloses an electrical vehicle DC charging module controller program on-line upgrade system mainly used for DC charging module controller program on-line upgrade. The on-line upgrade system process comprises selecting different controllers through IP addresses, and transmitting to-be-upgraded program to the selected controllers through the Ethernet; waiting for target devices to receive the to-be-upgraded program; transmitting a program upgrade instruction through the MODBUSTCP protocol; and upgrading the to-be-upgraded program to external FLASH chips of the controllersby the target controllers according to upgrade instruction requirements. By adoption of the technical scheme, the DC charging module program upgrade problem can be effectively solved, inconvenient maintenance environment of a JTAG mode is prevented, the problem that in the prior art, operations of engineers are uncontrollable under the JTAG mode is also prevented, and program upgrade records and program version numbers can also be detailedly recorded in the controllers.
Description
technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an online upgrading system for a controller program of a DC charging module of an electric vehicle. Background technique [0002] In the actual engineering application of DC charging modules for electric vehicles, from product development to mass production, it is usually necessary to continuously improve and perfect the DSP software system, which requires repeated upgrades of the DSP program. If the traditional DSP software upgrade method is used, the control board of the charging module needs to be removed, and the emulator is connected through the JTAG port on the circuit board to upgrade. This not only increases the workload of the upgrade program, but also easily causes device damage or wiring errors during the disassembly process. This is very unfavorable to the repeated upgrade of DSP in the process of product development and design, and seriously slows ...
