Begin a series of articles about hybrid cars.

More and more often on the roads of the city can be found in hybrid cars. The right stopped the Prius in the 30-m or 20-m body, to the left, the Honda Civic Hybrid. Hybrid cars are becoming more.

Today let's talk about a high-voltage battery of a Toyota Prius and the basic laws of operation of hybrid cars.

By itself, the battery is not the main driving device of a Prius. Battery (HV battery) is not only for the movement of the car, it acts as a damper ("energy storage"). For example, if the Prius is moving at a speed of 50 km/h, the engine allocates the excess energy that accumulates in the battery. When braking also produces excess energy that is "stored" in the battery. As soon as the car stopped, the engine stalled – then energy with CDH. If you need to warm up the cabin or the engine, the energy released is stored in CDH. It always happens: on-Board computer calculates the excess energy and begins to store it for future use.

But if the car starts moving, or the driver needs to dramatically increase the speed of the car – one energy engine enough, the onboard computer begins to help him: the energy from the battery is used to operate the electric motor. In other words, "riding on the battery of the Prius is a side effect.

The laws of operation of hybrids

Act 1. Not to leave the car permanently in the Parking lot

There is such a thing as the self-discharge of the battery. Toyota Prius HV battery has self-discharge approximately 10% per month. Assume that the car was left for six months. Leaving the car, you thought that the battery drain is only 60%, and 40% will remain.

The idea is wrong.

Remember that when the battery level drops below about 33%, banks battery starting to happen, irreversible chemical processes that Deplete the battery.

Act No. 2. Not to go without gasoline

If the tank is empty, a while the car will continue to move through the resource HV battery. But there will come a time when the battery level falls below 33%. In this moment starts an irreversible chemical reaction: one of the "cans" of the battery is outside the "norm" begins to "boil". As a result, the battery goes down. Replacement is inevitable.

Law No. 3. Try to have the vehicle repaired only by professionals who understand what is a hybrid

Many owners of hybrid cars, especially if they understand mechanics, I believe that will be able to repair your car yourself.

It should be noted that sometimes this actually works. But in most cases, unskilled invasion mechanics, as well as electronics, can lead to very costly repairs.

To costs can lead another astray. For various reasons the owners of the Toyota Prius for some reason trying to charge the HV batteryв living conditions. To do this in any case impossible! To charge this battery need a high-precision device, since otherwise overcharging of the battery which will result in its failure.
