Electric vehicles with range extender

The automotive industry is now more than ever before the challenge of making mobility sustainable world, affordable and environmentally sound. The CO2 debate has been the use of secondary energy source “electricity” is set for the individual at the center of discussion. This play not only with purely electric vehicles, the so-called plug-in hybrids, which have a rechargeable Dell Studio 1735 battery from the power grid and use it as both an all-electric drive and an internal combustion engine path, then a special role.

The battery technology is on these concepts, the key element. There are great efforts to develop suitable vehicle battery systems. For the foreseeable future, the lithium-ion technology is to be preferred, even if there are still technical limitations that must be sent to expand. This includes in particular the behavior of the Dell xps m1730 battery to provide at extreme ambient temperatures, a limited load capacity or a limited power for driving, heating or cooling the passenger compartment.

An efficient solution for the control of such restrictions may take the form of a so-called range extender module (SEM). SEMs are small, usually combustion engine-driven generators, which are used only when needed. For a virtually independent from the Dell Latitude E6500 battery range is possible, which will affect the acceptance of electric vehicles at the customer crucial.

The properties of these modules to the specific operating conditions such as significantly higher NVH requirements, less critical requirements for start time and dynamics in the operation or reduced life cycle requirements to adapt. The analysis of this specific requirement profile is unconventional solutions, such as an external combustion or low-vibration, low space-rotary engines to the list of considered alternative solutions.

After almost one year trial period in FEV LiIon battery electric vehicle with REM provides important findings that confirm the benefits of an SEM approach. The Wankel engine used allows a package of REM in the space of the former tanks, the volume was reduced to twelve liters, and features a excellent NVH characteristics. After extensive dynamometer and road testing the vehicle with REM was approved for road traffic.

In addition to the NVH adjustment and the everyday use the designers did not ignore the system cost in its sights. Since the cost of a REM about 1-2 kWh Li-ion battery capacity corresponding to the overall costs compared to a pure electric vehicle can be reduced significantly. In the present vehicle would reduce the costs of the “system” by the electric drive REM by about 30%.
