Electric vehicle (EV) industry

All-electric vehicles (EVs), also referred to as battery electric vehicles, use a battery pack to store the electrical energy that powers the motor. EV batteries are charged by plugging the vehicle in to an electric power source.
The key components are
Battery : Which has the stored energy
Motors : Which converts this into rotational energy for mobility.
Controller : Is an electronic hardware device +software which works very closely with the motor and is usually bundled with. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical faults.

The motor of an electric car converts the current from the battery into mechanical energy. This is done by a fixed magnetic part (stator) and a moving part (rotor) that is made magnetic by electricity. If two positive poles are facing each other due to the electrical charge, they repel each other - and the moving part of the electric motor rotates.
Electric motors develop similar torque at low as well as at high speeds. Theoretically, therefore, a rigid connection between the motor and the drive shaft would suffice for them. In practice, however, an input gearbox is usually used as a so-called reduction gear, which reduces the speed of the motor by a factor of about 1:10.

The motor of an electric car consists of two electromagnets - stator and rotor. The stator is immobile and generates a constant magnetic field with the help of direct current. The rotor is rotatable and produces its magnetic field with alternating current. The two magnets alternately attract and repel each other. The rotor rotates - and thus sets the car in motion.

The inverter is also called a converter. This is because it has the task of converting the 3-phase AC voltage of the electric motor into a DC voltage for charging the battery when braking. Conversely, when the electric motor is driven, the battery's DC voltage is converted into a 3-phase AC voltage.

Lithium-ion batteries are the heart of our electric cars. They are particularly powerful and have the highest energy density compared to other batteries. This means that they can store the most energy per kilogram of battery. Lithium-ion batteries have numerous advantages: due to their compact size, more individual lithium-ion batteries fit in your Opel electric car. So you can travel further. They also require less energy to cool the vehicle battery to its optimal operating temperature.

Also good to know: our batteries are not affected by the so-called "memory effect". You can recharge your electric vehicle battery as often as you like - even through mobile fast charging - without any loss of performance.

Independent studies estimate that you can drive 250,000, even up to 500,000 km with the battery of an electric car1. The durability of our batteries is therefore probably on a par with that of our combustion engines. That's why we give an 8-year guarantee on our electric car batteries, or 160,000 km of driving.
