Michigan compressor supplier Masterflux has released the Masterflux eBTMS, a Battery Thermal Management System platform for EV applications.
Masterflux’s parent company Tecumseh makes reciprocating compressors that are powered by AC and used in stationary applications. Masterflux compressors are hermetically sealed, variable-speed rotary compressors powered by DC and designed for mobile applications.
The Masterflux eBTMS is offered in three capacity ranges, which cover most EVs, from small 3-wheel passenger vehicles to long-haul trucks and mass-transit buses. Air-cooled and liquid-cooled configurations with up to 350 W of cooling capacity are available for small vehicle applications, and a liquid-cooled configuration with up to 7 kW of cooling capacity supports larger vehicles.
Masterflux General Manager Robert Terry said, “Direct DC compressors eliminate the need to convert DC power to the AC power that is required to operate traditional compressors. This reduces the complexity of the power electronics, improves the coefficient of performance, and reduces size and weight when compared to using traditional inverter/compressor technology.”
