Battery Management System Hardware Concepts: An Overview

I note that this article refers to several example EVs, not just the iMiEV, e.g. the Smart 4-2, Tesla.

Further in the document, we find that the sensor is a LEM CAB300 which has these specifications: ...
• Unipolar + 12 V battery power supply ...
Output signal: CAN.C (500 kbps)

This must be the LEM current sensor for another vehicle. The iMiEV sensor (yes, a LEM, but they make a lot of sensors) operates from 5 V and the output is analog, not CAN.

Information on the iMiEV current sensor can be found here: viewtopic.php?f=23&t=4718
