ZhiDou EV forum

Hi everyone,

I hope you are doing well. I would like to ask if anyone might have some free time to point me in the right direction.

I am currently searching for the EV05 software and firmware (BMS tool) in order to unlock and update the BMS on a ZhiDou D1. I’ve managed to find it on a few Chinese websites, but downloading it requires a Chinese phone number or WeChat verification, which I unfortunately don't have.

Therefore, I wanted to ask if it would be possible for someone to share the EV05 software (along with any necessary firmware) here, or via a direct link or PM. The Chinese version is completely fine!

Additionally, I would like to know which CAN-USB adapter is guaranteed to work with the ZhiDou D1 and the EV05 software. Would any of the following options work, or is there a specific one I should get?

• Lawicel CANUSB dongle

• GCAN USBCAN adapter

• A generic Dual-Channel CAN Analyzer with a 120R termination resistor

• Or are there any other specific models you would recommend?

Thank you very much for your time and help!

Best regards

Hi,

Getting the complete EV05 software package, including the BMS firmware files and documentation, is not easy. Some people sell the complete package for around €500.

This is one of the main reasons why the OBD unlocking dongle was developed. It provides a working solution without the risks associated with manually flashing the BMS.

There are also some hardware limitations to consider:

20-cell battery packs are not supported for firmware flashing.
Not all 24-cell BMS units can be successfully flashed with the unlocked firmware, some battery pack variants simply do not support this modification.

The advantage of the OBD dongle is that it works with all ZhiDou D1 battery pack variants, without requiring any BMS firmware modifications. This makes it a much safer and more universal solution.

Best regards
