Selecting BMS Transformers for Isolated Communications in High Energy Storage

Battery Management Systems (BMS) that integrate isolated communications are expected to be an important part of the safety and security of the battery system. To help BMS designers select the right signal transformer, a Bourns app note provides an overview of battery monitoring ICs and battery cell chemistries. It includes important transformer safety features and recommended evaluation tests and electrical characteristics that will aid in increasing Li-ion cell lifespan while enhancing safe operation for end users.
