FEV adds Hybrid Solution to its Platform Family for Electric Vehicles

According to FEV, China is experiencing a revival of hybrid technology, infact China's current best-selling so-called NEV- (New Energy Vehicle) SUV has a 40 kWh battery and an internal combustion engine as an energy conversion system in a serial hybrid configuration.

The NEV category includes purely battery-electric cars and those with fuel cells, plug-in and serial hybrid vehicles. Automobile manufacturers thus face a particular challenge because the parallel development of both a native BEV (Battery Electric Vehicle) and a classic internal combustion engine platform for different market needs significantly increases development costs.

FEV, now introduces as the latest member within its BEV platform family a solution that can do both: as a native state-of-the-art BEV platform, it is suitable for use in both pure battery electric vehicles and cars with a serial hybrid concept. A highly efficient energy conversion system from FEV is used for the latter.

Hybrid-BEV - the name of FEV's latest development - is based on the company's native BEV platform, but at the same time serves the demand for hybrid solutions for the Chinese market, for example. At the same time, this solution helps to reduce vehicle platform development costs.

"Our hybrid BEV is an all-in-one solution that eliminates the need for additional platforms and associated development and manufacturing facilities for automakers. In this way, we create enormous cost advantages that are not only important for smaller OEMs or start-ups," said Professor Stefan Pischinger, President and CEO of FEV Group.

In addition to the great cost-saving potential and weight and installation space advantages, Hybrid-BEV offers a high range with minimal CO2 emissions. Primarily when FEV's highly efficient energy conversion system - which in serial hybrid configuration is not connected to the drive wheels but directly supplies the power for electric propulsion and battery recharging - is powered by carbon-neutral e-fuels.

"In addition to the roadmap to phase out coal, we also need clear regulations that lead to the reduction of fossil fuels while increasing the use of e-fuels," said Pischinger. "The introduction of e-fuel quotas and planning guidelines for mineral oil suppliers and service station operators, including a complete ban on fossil fuels, creates legal and business certainty. Additionally, this provides the possibility of being able to operate hybrid vehicles in a CO2-neutral manner."

Hybrid-BEV also provides purchase incentives in terms of range, for example, in the D/E (mid-range and upper mid-range) company car segment, which is essential for automakers. Here, an electric range of 130 to 170 kilometres (80 to 105 miles) is possible thanks to a battery capacity of approx. 30 to 40 kWh. Combined with a tank volume of around 40 litres (8.8 English gallons / 10.6 US gallons) for the energy conversion system, this results in a total range according to WLTP of approximately 1,000 kilometres (620 miles) without a stop. The overall efficiency of the concept also benefits from the reduced battery capacity. This results in a weight advantage of around 200 kg (440 pounds) compared with a pure BEV platform.

FEV's Hybrid-BEV platform also impresses with an exceptionally compact integration of the energy conversion system, including generator and e-drive in the front of the vehicle. As a result, the long-wheelbase of a typical BEV platform remains unchanged. The same applies to the seat height. However, the reduced battery capacity compared with a pure BEV and the positioning of the battery in the underbody mean that space is gained in the interior. In addition to the fully available trunk volume, rear passengers benefit from more generous footwells without compromising battery capacity: a so-called foot garage integrated into the floor assembly creates the corresponding space.

The customization options for hybrid BEVs have only a minor impact on the BEV base platform.
