An electric vehicle has between 20 and 30 moving parts in its drivetrain. A petrol car has over 2,000. That simplicity translates into less maintenance, fewer things to break, and a fundamentally different driving experience.
The electric motor
An electric motor converts electrical energy from the battery into mechanical energy. It does this with 85-95% efficiency, compared to around 30-35% for an internal combustion engine. The key practical difference: maximum torque is available instantly from standstill, which is why EVs feel so quick from traffic lights even with modest power figures.
The battery
The battery is typically 30-40% of an EV's total cost. Modern batteries use lithium-ion chemistry, with capacities ranging from around 40 kWh in budget models to 100 kWh+ in premium ranges. Real-world range depends heavily on temperature, speed, and use of climate control.
Regenerative braking
When you lift off the accelerator or brake gently, the motor reverses its role and acts as a generator, converting kinetic energy back into electricity and sending it to the battery. This is why EV brake pads last extraordinarily long — on most journeys, the friction brakes barely engage.
Charging
Three levels: slow (standard home socket, 8-12 hours); fast (home wallbox or public AC charger, 3-8 hours); rapid DC (public fast charger, 20-45 minutes to 80%). For most drivers, charging at home overnight is sufficient for daily use. Public fast charging is primarily for long-distance journeys.
