Opel Ampera uses a Voltec propulsion system which consists of electric motors, motor / generator plus heat engine. All three power sources are connected to a planetary gear system in order to transmit power to the deck then in front of the car. One of the electric motors, the lowest one acts as a generator when the car is in extended-range mode. The electric motors are powered by a battery T-shaped battery is a battery of 16 kWh advanced technology with its own heating and cooling system. The model uses Li-Ion battery and offers a range of 40 to 80 km. Autonomy is influenced by driving style and the number of additional customers that operate on the board of the vehicle. For example, if the air conditioning work the maximum it will affect autonomy in electric mode. The battery has 288 cells and provides a voltage of 360V. Battery weight is 190 kg. Thanks to its climate, Ampera’s battery can run smoothly, says Opel, even if the outside temperature is in the range of -25 to 50 degrees Celsius.
To increase the autonomy amps uses a petrol engine 1.4-liter Ecotec. It is well known on the Corsa, develops 86 hp and normally works 54 kW electric generator. The engine complies with Euro5 emissions standard.
The propulsion system of the Opel Ampera has four operating modes, as we exemplified. Also, the steering can choose between four driving modes, and these are: normal, sport, mountain (recommended for mountain roads) and hold (heat engine operates continuously even if the battery is completely discharged).
