High Voltage Battery Junction Box Reference Design

Overview

The RD9Z1-638BJBEVM is a hardware tool for evaluation and development, ideal for rapid prototyping of high-voltage battery junction boxes (HV-BJBs) in electric vehicles. This board evaluates the functionality of the RD9Z1-638BJBEVM device and allows the user to connect to a power distribution unit (PDU) for voltage, current, temperature sensing and contactor status diagnostics. The RD9Z1-638BJBEVM reference design can help accelerate your project development. It is a flexible, independent function board with high integration, smaller size, and compatibility with electric vehicles and electric buses.

How does the kernel driver work?
I found a kernel driver code on the Internet. I set up the environment XP SP3+VC++6.0+WINDDK FOR XP +DRIVESTUDIO3.2. The code ran and generated a .SYS file, but I don't know how to run it. Can anyone
Who has the telent client code for WinCE?
WinCE C# code, thank you if you don't have enough points, please add more.

Fuse blown self-healing circuit
The working principle of the circuit of the device is shown in Figure 6. When the fuse FU1 is intact, the neon bulb ND is short-circuited and does not light up, and at the same time, the ① and ② pins
Is my interrupt response time normal?
It takes 1.4ms from the first instruction of ISR to the first instruction of interrupt thread IST response (setting an IO output). Some friends in the forum have tested it and said it only takes 400us
