Energy efficient EV Cabin heating for extended driving range
Decarbonisation of the transport sector depends on greater uptake of EVs, but buyers worry about driving range and comfort- especially in winter where cabin heating drains the battery and reduces the range up to 50%. Alpcon, AAU and Insero E-Mobility will develop a supplement for EVs in cold regions - a battery independent effective cabin heater
Range anxiety presents one of the biggest barriers to EV uptake. The goal of this project is to extend the EV driving range and comfort in the wintertime. This is reached by developing and demonstrating a self-powered cabin heater that is affordable, highly energy efficient and entirely independent of the car”s battery. The technology is based on Alpcon” s patented HEXTEG technology, which uses temperature differences within the heater to generate electricity to power the integrated ventilation fan (plus surplus electricity), meaning no battery dependence, increased heating efficiency and no loss of driving range. Heating related Co2 emissions are also reduced. The long term commercial goal of the project is OEM integration of the technology at factory level, while the short term goal is retrofit of ENTIFFIC EV into existing EVs. Once the infrastructure for biofuels is further developed, ENTIFFIC EV will be adapted from LPG input to zero-emis sion sources making it suitable for multi-fuel operation.
The main tasks in the project:
- Development of the product for integration
- Field test of technical and user-oriented aspects
- Evaluation and optimization incl. costs and production capability evaluation
- Dissemination of results
These activities will contribute to paving the way for market launch in 2017.
