EV CARS

Specialise in EV's b

Regenerative Braking

captures kinetic energy from breaking and converts it to electrical power that charges the vehicle.

Heat Pump

Scavenges and compresses excess heat from the battery and electrical systems

Battery Management System

Constantly monitors the High Voltage Battery. When using DC charger - controls voltage, current and temp.

AC and where does the power come from?

Alternating current - power comes from the grid

DC and where does the power come from?

Direct Current- stored batter power.

KW?

Kilowatts - movement of energy

kWH

Killowatt- hour - used talking about battery capacity.

3 Pin Domestic plug

• Slowest way of charging

• takes 30h+ for full charge

• strains socket

• risk to overheating

• not recommended

Home Charging

• Convenient

• Only one end needs to be plugged in

• Preferred way of charging (recommended )

• lower night time tariffs (reducing costs for charging)80% charge in less than 8.5h

Public charging ~ what are the 2 different kinds

Destination charger and On the road/ Rapid Charging.

Destination Charger

While you’re doing something (shopping/gym).

• Powered by AC

• Mostly found in Car parks (you are out for at least 30min+)

• Might not have cable attached (recommend always having your own)

• Powered by AC charging

• from 7kwh - 22 kw

On the road/ Rapid Charging.

• Quick top up on longer journeys

• Much faster

• 50-350KW (Charging output)

• AC & DC

• Time spent is determined by how powerful the charger is

• Usually under 30min

• Will come with a cable

• More expensive.

Self Charging

• The engine recharges the battery

• no further charging required.

Electric motor

Puts the electrical energy to work - driving the vehicle

What kind of cable/ charger is supplied with the EV’s?

2 pin charger

On Board Charger

Converts AC to DC

Hybrid Starter Generator

• Supports the internal combustion engine on hybrid cars, replacing the tarter motor and alternator helping reduce fuel consumption.

The three kind of vehicles

• Hybrid

• Plug in Hybrid

• Pure (Full EV)

Purpose of the High Voltage Battery?

Stores and supplies all power needed to operate.

12v Battery

• Helps preserve the charge in the main battery.

• Provides the charge needed to run standard features e.g. lights, wipers and the audio system
