Current sensors

Battery current sensors for the Lithiumate™ BMS

The BMS needs to know the battery current for proper operation. Whether there is a need for one or more current sensors depends on the application

If the source current (charging current) is in the same range as the load current, only one sensor is needed

Application		Number of current sensors required
CAN bus already has the value of the battery current		None
No battery current info on CAN bus	Source (charging) current is in the same order of magnitude as the load current	One, measuring the entire battery current
	Source (charging) current is much lower than the load current	Two: •one measuring just the load current •one measuring just the source current

You may use your own current sensor, or one of these Elithion current sensors:

In-line	On-board	Cable mount
