Now this is very interesting, the heart of electric car. I found this article informative enough to let us know that the heart of electric car is Not the engine. You will find out below.
The heart of any electric car conversion is the batteries. You will need special batteries, called deep cycle batteries in order to make your electric car work properly.
These batteries allow you to charge quickly and discharge further than regular car batteries normally found in your vehicle now.
Example of Deep Cycle Batteries
They are called deep cycle because normal batteries would be wrecked by the frequent draining of the batteries used in the system. Think of it as pouring water out of a glass. A regular battery you can only pour about 10% of the water out, but a deep cycle battery you can regularly discharge down 30% or so.
You don’t want to go lower than 30% down though. Topping up a battery that is to the 70% level is as low as you go.
Where do you find deep cycle batteries? We have been living off the grid for over 10 years now and have been living with battery systems to run our home for that long.
The same batteries used with solar panels and wind generators are easily fitted to electric car conversions. They are easy to find, but can get expensive if you don’t know where to look. The plans show some great sources of free batteries too. That is a great savings since the batteries for an electric car can be one of the greatest expenses.
Watch this interesting video that shows some high school students building their own electric car, including a good shot at the batteries.
A bunch of high school students can do it, so can you.
Finding batteries is not that difficult either, isn’t it time you got started. Learn more how you can do it with Electric car Plans.
You will need to locate about 20 deep cycle batteries for your car as well. The plans outline sources of batteries, even free batteries that you can find easily. The same source will probably have free DC motors too.
It’s just a matter of asking.
Why do you need 20 batteries? In order to achieve a range of 200 miles you will need this many batteries.
A controller is needed to fix the amount of current flowing from the batteries to the motor which determines how fast you go. The controller is connected to your old gas pedal linkage for smooth control of the vehicle.
In order to charge your batteries between trips you will need an on board battery charger. That way you can simply just plug it into any common AC circuit and get charged up again.
