Back in 2008, the global crude oil prices were at its highest at $150 per barrel.
Because of that, local gasoline prices reached a dizzying level and many car owners could cannot afford to fuel up their vehicle.
Some had to abandon their car at home and use the public transportation.
Others tried fuel saving solutions such as bio diesel and hydrogen fuel generator.
At present, the most practical ways to reduce your energy expense bill is by using a pure electric vehicle (EV).
However, a new EV from the dealership is still very expensive.
A normal sedan electric car costs upwards of $40,000.
As an alternative, many car enthusiasts are converting a gasoline driven car to use purely electricity from their home garage.
How do you retrofit a car to EV? The process is quite simple.
The idea is to replace the internal combustion engine (ICE) with a DC electric motor.
When the engine is removed, all its supporting system such as radiator, gas tank, fuel lines and fuel pump are redundant and to be taken out as well.
To generate torque, the electric motor has to be connected to the existing transmission unit.
This is the tricky part of the EV conversion process.
The shaft of the motor and transmission core have to be aligned perfectly.
Any misalignment will create vibration and reduce the efficiency of your homemade electric car.
To setup the motor, you will have to custom made a steel adapter plate.
If you are not familiar with machine tooling, it is better to outsource this portion of the work.
To power your electric car, you will need to use a series of lead acid battery.
This kind of battery is favorable because it is readily available and not too expensive.
A normal EV will require 10 to 15 units of battery.
To save cost, you can always use reconditioned battery pack from electric golf carts.
