EV motors (electric vehicles) are basically DC motors (direct current motors) in most cases and voltage ranges from 96 to 192 V. Alternatively, alternating current motors (alternating current motors) can be used and in this case the voltage range can be between 240 and 300 volts. The most common electric car engines are DC motors, as these engines can be installed very easily and are generally not expensive than AC motors. Apart from the simple setup, there is another reason to rely on DC motors.
The ability of electric motors to increase their power to a fraction of a second is usually 5 times the original output. Thanks to this, DC cars can produce faster acceleration in a very short time, and this helps the car to perform better. However, this cannot be done until the engine stops. However, some cars are equipped with AC motors, as these engines allow any engine in the industry to be used in the car, which is quite advantageous.
The principle of operation of the car is quite simple:
Drive – In battery-powered vehicles, the operating principle is very easy to understand. The car is driven by an engine (electric motor), which takes its energy directly from the cells. There are gasoline generators in hybrid cars. Hybrid cars have a very sophisticated mechanism that is not covered by the article. Returning to electric cars, the simple mechanism avoids many parts, making cars more reliable.
Transmission – Compared to petrol-powered vehicles, EV engines cannot be pressurized to create greater torque by shifting to a lower gear. As we have seen, DC motors can increase performance for a few seconds, but car manufacturers do not use this option to increase performance. It can be stated that the electric car gearbox is only for speed control. The operating principle is also very different. It uses resistance and the lower speed is achieved by providing greater resistance to the engine.
Cells – Previously, the electric battery was the biggest drawback of electric cars, because on average these batteries are about 500 to 1000 pounds. Today, branded cars have sophisticated technology, but technology is not available at very affordable prices. Even cars with the smallest Li-ion battery will cost a lot because the battery is very expensive.
These are the main features of EV engines. Previously, electric car batteries were the same as car batteries (even today, many post-electric car packs use the same), but these items don't last longer. Gel electrolytic cells are expensive but persistent. If you want to invest in a reliable investment and battery, it's a good idea to stick to the latter.
