eBTM 2.0
Battery Thermal Management
PLUG & PLAY
COMPACT
& POWERFUL
STAND ALONE
Universal plug & play thermal management solution for traction battery packs
Ensures ideal battery performance and prolongs service life
Traction batteries will only function perfectly in narrow temperature ranges:
Battery cells do not deliver the desired output when cold and may degrade over time when too hot. eBTM 2.0 monitors the current temperature and actively balances between cooling and heating circuits, thus always hitting the “sweet spot”.

Stand-alone Battery Thermal Management Unit
Cooling Provides optimal cooling when battery packs are under stress or used during hot weather conditions
Pre-Conditioning Sets the perfect temperature for battery cells during charging phases or before operation
Heating Delivers heat during extremely cold ambient conditions
Balancing Adjusts the temperature dynamically during different driving phases
6x Battery packs Entirely scalable system
Versatile and suitable for every application eBTM 2.0 is a precisely tuned system solution for light commercial vehicles, busses, trucks, construction and agricultural vehicles. It is also a perfectly scalable solution: Starting with just one unit, every type of electrical vehicle can be equipped with one or several battery cooling units.
