EMUS CAN Current Sensor is a high accurate device used to measure currents with high precision. It replaces an interconnecting bus bar, and due to the galvanic isolation between the sensor and the conducting part, it can be installed anywhere in the battery pack between two adjacent series-connected cells. The current sensor measures the current passing through it and communicates by CAN messages with the Control Unit. It also includes 1 or 3 voltage ports depending on your needs.
