Carmaker respond intuitively allergic to the demand, to normalize the traction battery BEV. The result is a restriction of freedom of design of the designers.
The overwhelming majority of the cars of a class has a similar large-sized engine compartment, it over similarly sized internal combustion engines with four or six combustion chambers (cylinders) and finally with ever-equalizing power spectra.
engines, transmission, turbocharger, almost all technical components, be installed for reasons of cost and in vehicles from other brands. Bodywork and silencer probably make the crucial difference for the layman.
then makes the accusation to, the normalized removable battery make all the cars more equal?
is correct: The electric drive allows, as distinct from the combustion drive, Flexibility within certain parameters, having to accept without deductions for efficiency and effectiveness. The drive of the BEV essentially consists of three elements: the traction battery, the electric motor and an electronic unit, that, interposed, Equal- to AC current, can be dosed acceleration and also provides the energy during braking by means of recuperation Rückgwinnung.
The control electronics can theoretically hold a number of programs from the factory, pretend the relationship between performance and range. In principle, the electronics control, must reach the motor how much energy per time. Depending moderate the program, the higher the range. Manufacturers determine the maximum vehicle performance by the performance and the number of installed electric motors. As soon as the traction battery satisfies the minimum electrical requirements according to the standard, the control electronics will supply the engine with a reliable power. The electric motor uses the energy supplied at any speed with high efficiency.
storage technology evolved over time further, so that progress can be used in the vehicle inventory. The limiting factor is always the electric motor. Whose maximum power achieved, so still reach for the user increases with further improved batteries but.
Motorized vehicles are built around man. But the normalization of our roads (lane widths, plots) lead to very similar dimensions in vehicle. Normalized traction batteries can be used in various combinations yet. Since rechargeable batteries are the heaviest components of the vehicle, they are increasingly integrated into the sandwich floor of the car. The low center of gravity of the vehicles leads to good road holding and controllability for the / * the driver in.
