Recuperative braking like electric cars to charge on the go

Рекупиративное торможение: как электрокары заряжаются на ходу

Electric cars rushed into the automotive world with a Bang ousted from his large petrol and diesel engines, with a large number of emissions from the exhaust pipe. The adaptability of these new machines just don’t fit in the head, because a few years ago, we couldn’t think of what to fill the car will be possible from a home outlet.

The uniqueness of electric cars lies not only in their motors and batteries. They began to use such functions which were not previously met and one of them is regenerative braking. Many drivers, years of driving petrol cars with a manual transmission, know this fact – if the throttle and rolling in gear, the fuel will not be consumed even when the tracking engine. But can the fuel added to the tank under these conditions? Of course not. But in the case of carts is a very real and working mechanism. About how it works, Auto Informant will tell in this article.

So arranged that the car will emit a large amount of kinetic energy that comes from within the movement. How to use it and send in the right direction? Quite simple. Suffice it to recall a Dynamo on a Bicycle. It was attached to the wheel and rotates during the movement, gave an electric charge to the lamp that lights even without a battery in the design. The brightness is directly dependent on speed. This is one of the simplest examples of the use of the kinetic energy in vehicles.

Speaking about cars with internal combustion engines, there is also present a similar principle, but the energy comes not from the wheels, and crankshaft revolutions. The associated belt drive to the generator, it passes to it the spin that creates the friction. It already creates a charge that is transmitted to the battery. What happen to the kinetic energy from the movement and braking? She is entirely spent on brake pads, erasing them. That is, it is not just benefits, but also harms. In electric cars this nuance has been revised, which would give another plus to the list of their advantages.

Almost all modern electric cars are equipped with a regenerative braking system. And not just electric cars. This property have electric trucks, bikes, and even scooters. The principle of operation of this function is quite simple. At the time of deceleration of the vehicle all the kinetic energy returns back to the engine, which at this moment acts as the generator, returning a portion of the energy back to the battery. In an electric car there is still normal brake, but given the fact that getting energy to the wheels, the engine starts to slow down, the demand for them disappears. They are only used for an emergency stop, because the car starts to brake as soon as the driver releases the gas pedal.

Prilovchivshis maximum use of this feature, the owner of the electric vehicle will appear a considerable number of kilometres of the reserve. Of course the amount of regenerative energy depends on the amount of braking and deceleration, which are close to the maximum in terms of urban rhythm. On country roads this feature is almost not noticeable, but the exceptions are long descents where you can, coasting, thereby adding to the supply of energy.

In such an exceptional way you can convert up to 80% energy, which will allow you to travel much longer on a single battery charge. Another feature of this function is that if the driver has not calculated the reserve, and stalled on the track, he can always catch hold of a passing truck and recharge the battery.
