2.4GHz SAW Filter for wBMS

# Automobile

The number of cells in batteries used in electric vehicles tends to increase as the capacity and voltage increase. Battery management systems require additional monitors and components, including wiring and connectors between monitors. Besides increased cost and weight, there are also concerns about the risk of disconnection and poor connections. However, a wBMS (wireless battery management system) that enables wireless communication between monitors can reduce the number of components, such as wiring and connectors.
Kyocera's SAW filters for wBMS contribute to the realization of high-performance wireless communications with their compact size and excellent low-loss and high attenuation characteristics.
