Conversion of

Internal Combustion Engine

Vehicles to Battery Electric Vehicles

Platform

Citroen C1, Toyota Aygo, Peugeot 107

Reasons for Conversion

• Substantial (long term-)increase of fuel prices

• Environmental aspect (Kyoto protocol)

• Low maintenance & vehicle operating costs

• Zero emmision @ tail pipe, no nano partical emmisions

• EV’s are far more efficient then ICE’s

• EV’s can help balance the Grid Power

Removal ICE related Components

• Engine

• Starter motor

• Gear shifter

• Clutch & flywheel

• Alternator

• Fuel tank & lines

• Air filter

• Exhaust system; pipes, mufler, lambda sensor, catalytic converter

• Mechanical pumps & belts

After removal of ICEV Parts

Installment of EV Parts

• Adapter plate & coupling for HP Version (between motor & transmission)

• Liquid cooled AC Induction motor & controller / inverter

• Batteries & Battery Management System (charging, cell balancing,

temperature control & alarm, over charge & over discharge)

• Fluid (Immersion-)Heater / Ceramic Heater

• Vacuum pump (to supply vacuum to the brake booster)

• Circulation pumps (for cabin heating, E-motor & inverter cooling)

• Battery Monitoring; CAN Display / E-Meters (SOH, SOC, A, V, Ah, ...)

• Battery charger (on board, 1-phase, optional 3-phase)

• DC-DC Converter (high Voltage input Switched Power Supply)

• Potentiometer or Hall sensor box (signal from gas throttle to inverter)

• Relays, main contacter, emergency disconnects, ground fault interupter

• Aluminium wheels and low rolling resistance tires
