Recuperation heater increases efficiency of electric vehicles

20 July 2014

REO UK has introduced a high voltage recuperation heater for electric vehicles - the D330 - which brings significant efficiency improvements to electric vehicle thermal management systems.

Forming an integral part of the vehicle thermal management system, the D330 reduces energy consumption and offers increased cooling efficiency during emergency braking.

In conventional fuel engines, any waste heat generated is usually reused to heat the cabin. However, until now electric vehicles have had to use electrical energy for heating both the cabin and the batteries during winter.

This has the detrimental effect of diminishing battery life, increasing the running cost and detracting from the potential maximum range. The key barrier to the adoption of electric vehicles has been battery life and range.

The BWD330 minimises this dependency on the battery by using the energy generated from the act of braking, which is stored and reused for heating as and when required.

The unit weighs less than 10kg, has a rating of 420-450Vdc and a maximum braking power rating of 60kW.
