With the increasing popularity of electric cars, the automotive world is being turned upside down. Electric cars are different in many ways from the old familiar combustion engine cars. Obviously, the technology is different, but charging also works very differently than refueling. We list everything you need to know about electric cars below.
The main difference between an electric car and a fuel car is the technology, so let's start there. Instead of a combustion engine, an electric car has an electric motor and a battery pack. We're not going to explain exactly how that all works in terms of technology, but what the practical implications are.
The battery is a crucial component of an electric car. The capacity of the battery is expressed in kWh (if 1 kW of power is delivered for 1 hour, it equals 1 kWh). The battery capacity determines the range. In practice, the range is usually lower than the stated range. With the advent of the WLTP measurement method, which replaced the NEDC method, the manufacturer's statement did become more realistic.
When it is cold outside, the battery performs at less than optimal levels. This reflects in the range. In the long run, however, cold is not causing ongoing damage to the battery. Whereas, extreme heat will damage the battery. If a battery gets too hot, the range will be lower in the future.
It is also best for the life of the battery to charge from 20% to 80%. A completely empty battery as well as a completely full battery are things to avoid. Battery management itself ensures that there is always a buffer left. The consequence of this is that you never have the full capacity of a battery at your disposal.
EVs also differ from conventional cars in terms of braking. This is because an electric car can brake using the electric motor. The electric motor then functions as a dynamo. This way it can recover energy as the vehicle moves. This system is regenerative braking and requires just one pedal. In fact, the brakes work by simply releasing the gas pedal. This is ‘one-pedal driving’ and is often easier for both old and new drivers.
