How do hybrid cars give a car way better gas milage?
i dont understand because its not like the battery is recieving energy from its own source, the electricity that the battery gets is essentially produced by the gasoline in the tank, so the gasoline is providing energy to the motor and electricity to charge up the battery. so if the power of the electric motor and the gasoling motor is being drawn from the gas in the tank how is it that a car can go so much further on the same amount of gas as compared to a normal car?

because the engine doesn’t run full bore all the time, only when batteries need a boost, like when you go up a hill.

well not all hybrid vehicles work like that … lets take the prius. it drives on the electric motor and then drives on gas to keep a charge but when you brake the brake system also creates a charge making the battery last longer… now vehicles are adding a ev mode where the vehicle would drive longer on battery so that you use very little gas… so a hybrid is just how it sound a combination of power to get you moving.. so it goes a little on electricity a little on gas instead of all gas… being able to split how often you use the gas allows you to use less of it.

Most hybrids have a brake regenerative unit that helps to recharge the battery on deceleration or braking.

The hybrids electric motor propels the vehicle untill the the battery is depleted at that point the gasoline engine kicks in. The gas engine alternator helps charge the battery, but the real benifit is when the driver steps on the brake. the electric motor acts as a brake by attempting to reverse direction. This process acts simalar to the alternator producing electricity (in laymans terms). This slows the car and recaptures some spent energy to recharge the batteries. This is why most hybrids get better milage in the city than on the highway. More stop and go driving more battery charging.

the car mostly runs on the battery, and the engine recharges the battery
