The architecture of an electric car
Of the Driving an electric car consists essentially of one battery pack, one Engine (or several) as well as one Charge and power management. As in the case of the modular electric drive kit (MEB) from Volkswagen, the so-called “skateboard architecture” is usually used. Here lies the battery well protected and space-saving in the sub-floor, the other components sit on the front and rear axles. All parts are connected to one another by high-voltage cables. There are mostly in the system 408 volts Voltage is on, i.e. significantly more than at the domestic socket (230 V). But it can be up to 800 volts, like with the Porsche Taycan.
Charging station, wallbox and more: this is how e-cars are charged
Most electric cars can be plugged into a household socket Alternating current (AC, 2.3 kW) “filled up” and in the vehicle from a current transformer Direct current (DC) can be shaped. However, it is much faster, safer and more practical to charge direct current on a “Wallbox“(Read everything you need to know here, including a wallbox test). With a wallbox is a Charging power of 11 or even 22 kW (400 volts, 32 amps) common, so charging is much faster. At public charging stations can it up to 43 kW (400 Volt, 63 amps). However, the charging capacity of the car must also be designed for this.
Energy storage: the battery in the electric car
The power electronics in the electric car
The engine of the electric car
The engine of an electric car is a very simple machine compared to a combustion engine. in the Electric motor will changing magnetic fields converted into motion. More precisely, permanently built-in change Stators (Magnet 1) through the energy from the accumulator constantly their poles. The one sitting in the middle or in the stator rotor (Magnet 2) is thereby alternately attracted and repelled, gets into a Rotary motion and finally ensures that the wheels start moving.
