Impact of thermal-electric networks on the usability of EVs based on a study with a C-segment car
(Proceedings of the 7th European Transport Research Arena 2018, 2018-04-16)One of the major concerns of contemporary Fully Electric Vehicles (FEV) is the high dependency of the maximum range on ambient temperature conditions. In some cases the range of an EV can drop by more than 50%. One of the ... -
Energy efficient control of a heat pump in fully electric vehicle
(Proceedings of the 7th European Transport Research Arena 2018, 2018-04-16)Since fully electric vehicles (FEV) do not have enough waste heat for cabin heating as internal combustion engine (ICE) vehicles and hybrid vehicles do, it is beneficial to employ a reversible heat pump in FEVs. The ... -
