Infineon has expanded its battery monitoring and balancing range with several new chips designed for use in battery management systems (BMS). The TLE9012DQU is its latest analog front-end battery monitor, capable of monitoring up to 12 battery cells connected in series and provides cell voltage measurements, temperature measurement, cell balancing and communication to the main battery management controller. The TLE9015DQU is a transceiver which enables several TLE9012DQU devices to be daisy chained together for applications which contain larger strings of batteries.
SAR Insight’s latest quarterly battery management IC forecast predicts that the market for analog front-end battery monitors will almost triple from 2022 to 2027, the largest opportunity being driven by use in E-Mobility including electric passenger cars, e-motorcycles, e-bikes and e-scooters. ASIL-D and ISO26262 compliance are critical for adoption in electric vehicles.
Outside of EVs a strong market for analog front-end battery monitor ICs is also forecast in battery power tools and energy storage systems, with unit shipments projected to more than double in both applications categories from 2022 to 2027.
