The Isolation Advantage
Battery fire caused by over or under charging of individual lithium ion cells is a major concern in multi-cell high voltage electric and hybrid
vehicle batteries. To combat this, each cell is monitored for current flow, cell voltage, and in some advanced batteries, magnetic susceptibility.
The IL41050 allows seamless connection of the monitoring electronics of every cell to a common CAN bus by electrically isolating inputs from
outputs, effectively isolating each cell from all other cells. Cell status is then monitored via the CAN controller in the Battery Management
System (BMS).
Another major advantage of isolation is the tremendous increase in noise immunity it affords the CAN node, even if the power source is a
battery. Inductive drives and inverters can produce transient swings in excess of 20 kV/μs. The traditional, non-isolated CAN node provides some
protection due to differential signaling and symmetrical driver/receiver pairs, but the IL41050 typically provides more than twice the dV/dt
protection of a traditional CAN node.
