eBTM 2.0

Universal Solution for Battery Thermal Management

Efficient Battery Conditioning in a Single Box

The Webasto eBTM is a stand-alone Battery Thermal Management Unit. It ensures the optimal functioning of water-cooled battery packs used in electrical commercial vehicles and guarantees ideal battery cell performance over the long term.

eBTM 2.0 Data Sheet

Provides optimal cooling when battery packs are under stress or used during hot weather conditions

Delivers heat during extremely cold ambient conditions

Sets the perfect temperature for battery cells during charging phases or before operation

Adjusts the temperature dynamically during different driving phases

Ideal Solution for Water Cooled Battery Packs

Thanks to several powerful coolant pumps included in the eBTM 2.0, optimal functioning of water-cooled battery packs is ensured. A 50/50 Water/Glycol mixture flowing through integrated battery cooling plates keeps the battery in its perfect operational temperature range.

Plug & Play Installation

For the customer's convenience, there are only a few standardized connection interfaces, which allow quick and easy installation and commissioning.

Compact but Powerful

Components for coolant & heating circuits, electrical water pumps and control units are already included in eBTM’s compact housing.

Variety of Installation Positions

A compact design and several fixture points ensure flexible installation. This way, the unit can be mounted in any position: e.g., on bus roofs or under the chassis of trucks or LCVs.

Scalable System Solution

It is a perfectly scalable solution: Starting with just one unit, every type of electrical vehicle can be equipped with one or several battery cooling units.

Discover Technical Excellence

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.

Webasto eBTM 2.0 monitors the current temperature and actively balances between cooling and heating circuits, thus always hitting the “sweet spot”.
