The market for lithium-ion powered vehicles and energy storage solutions continues to be red-hot, with additional growth forecasted for at least the next 10 years. However, these types of battery chemistries have stringent requirements for control communications. In this article, find out how new technology from Bournes is helping to meet this need.
New applications for lithium-ion batteries have necessitated the development of new battery chemistries. Regardless of the specific chemistry, though, a well-designed battery management system is needed to ensure proper operation.
Overview of Battery Management ICs
A typical battery monitor IC measures cell voltage and battery pack temperature, with some more advanced models also measuring current.
BMS High-Voltage Communications
In a high-voltage application such as an electric vehicle or energy storage unit, numerous battery monitor ICs must be daisy-chained, since each IC can only monitor up to 10 cells or so. Therefore, each IC in a BMS must be able to communicate with a controller, usually by way of a serial peripheral interface.
Advantages of Bourns BMS Transformers
In high-voltage battery applications, Bourns BMS transformers excel for numerous reasons:
● Use of enameled fully-insulated wire for high dielectric strnegth
● Expanded operating temperature range (-40 °C to +125 °C)
● Good noise immunity
● Easy communications setup
● Higher working voltages
