Why are M12 X-code connectors preferred for the BMS of new energy vehicles?

Q: Why are M12 X-code connectors preferred for the BMS of new energy vehicles?

A: M12 X-code connectors support high voltage of 800V and large current of 60A, with a temperature resistance range of -40~125℃. They can transmit cell voltage and temperature data in real time (sampling accuracy ±0.01V). Meanwhile, they feature an anti-reverse insertion design (key misalignment), which prevents battery short circuits caused by incorrect installation, making them suitable for the high-precision monitoring requirements of BMS.
