Tempering traction batteries

Traction batteries provide consistently good performance if they are kept in a temperature range between 25 and 35 °C. The electrical Battery Thermal Management (eBTM) from Webasto continuously regulates the temperatures of water-cooled batteries in buses, trucks, construction machinery and light commercial vehicles. Cooling and heating processes are optimized in a coordinated manner.

 

This guarantees the best possible range for electric vehicles, even in warm and extremely cold environments and under load, and extends the service life of the battery cells. The eBTM preconditions the cells to their optimum temperature during charging or before the vehicle is used. The Webasto device is compatible with the Webasto battery system as well as with customer-specific developments. The maximum output for cooling is 8 kilowatts and up to 10 kilowatts for heating.

Benefits of electrical Battery Thermal Management (eBTM)

Universally applicable

Plug & play solution in one device for the thermal management of water-cooled traction batteries.

Compact device

All components for cooling and heating circuits, electric water pumps and control units are included in the compact design of the eBTM.

Extended range

Benefit from up to 8.9 percent more range.

Faster charging

Batteries preconditioned with the eBTM charge up to twice as fast and increase the charging capacity by up to 24 percent.

Water cooling

A 50/50 water-glycol mixture ensures the ideal operating temperature of the traction battery with the powerful coolant pumps of the eBTM.

Flexible mounting positions

The compact, robust design and multiple mounting points allow flexible installation, e.g. on bus roofs or under the chassis of commercial vehicles.
