The energy memory

Different possibilities for the energy memory with electric cars

A quite important and central point for good electric cars is the suitable energy memory, because only if this is enough and one can also bridge sufficient reach by the car, the car is suitable for the everyday use.

Here nowadays there are technologies which make a reach of 500 kilometres without problems possible and which is suitable therefore also absolutely for the normal need. The quite clear favorite of most manufacturers for electric cars is the accumulator. On this occasion, are possible for cars of course only such accumulators which can take up an accordingly high energy density.

Important is with the used accumulators the so-called cycle firmness which defines how many unloadings and loadings the accumulator gets over without he loses in capacity. So that so low costs must originate as possible for the user accumulator in vehicles a very high cycle firmness show, so that they must be exchanged only seldom.

Such accumulators which work on the base of lithium are suited ideally here. Mostly they are combined with a so-called benefit brake which takes up the strength with the braking and converts again into energy which of the battery is supplied by which this one longer term receives and one can overcome therefore a longer distance. Friends of the motor sport know a similar system from the formula 1. Here are used such benefit braking in the so-called Cares system, indeed, in this case  the additional energy is converted into speed to have more swing short time and to be able to overtake therefore better.

Normal car batteries, how they in petrol cars are used to raise the start energy, are not suitable for electric cars, because they are not up so frequent unloadings and loadings laid out and would break very fast.
