Types of EVs
EVs offer an environmentally friendly alternative to traditional fossil fuel motoring whatever your needs. Incorporated into a company fleet for business use, EVs will also enhance a company's green credentials.
Types of Electric Vehicle:
- Battery Electric Vehicle
- Hybrid Electric Vehicle
- Plug-in Hybrid Electric Vehicle
- Extended-Range Electric Vehicle
Battery Electric Vehicle
Battery electric vehicles are powered purely by electricity. Unlike conventional car batteries, which start the engine and run items such as the radio or heater, the battery pack in an all-electric vehicle runs everything.
Crucially, it runs the controller which, in turn, powers the electric motor that replaces a petrol or diesel engine.
EV battery packs need to be powerful and long-lasting to provide an adequate range between re-charging. Regenerative braking 'tops up' the battery as you drive by capturing kinetic energy when the brakes are applied. This can increase range by up to 20%.
An average family saloon, with a range of around 100 miles, would typically have a 24kWh battery pack and be charged via a standard 13Amp domestic socket overnight on off-peak electricity. A full charge can be achieved in as little as 30 minutes through a higher power fast charger.
Hybrid Electric Vehicle
The hybrid electric vehicle is dual fuel. It is powered by a combination of electric motor and standard internal combustion engine, providing increased fuel efficiency particularly in stop-start city driving.
The electric motor boosts the car's ability to start and accelerate, and powers the car at low speeds over short distances when the internal combustion engine is least efficient. The engine kicks in at higher speeds.
The system also prevents wasting fuel idling by automatically shutting down the engine when the car stops.
The battery is recharged by both the engine and regenerative braking which captures kinetic energy when the brakes are applied.
Plug-in Hybrid Electric Vehicle
The plug-in hybrid electric vehicle, like the hybrid electric vehicle, is dual fuel, powered by both the electric motor and internal combustion engine to increase fuel efficiency. The battery pack can also be charged by the engine and regenerative braking.
The difference is the battery pack is larger, increasing the share of electricity used as fuel to power the car and it can also be plugged into the electric grid for charging at home overnight.
Extended-Range Electric Vehicle
An extended-range electric vehicle uses an internal combustion engine to power an electric generator that charges the battery system.
Unlike the dual-fuel system hybrid and plug-in hybrids, the electric motor is the only system to directly power the car and turn the wheels. The internal combustion engine only charges the battery system.
