How To Extend Your EV Mileage With Proper Tire Pressure

One of the major drawbacks of pure electric car is the limited drive mileage. Unlike a conventional automobile, an electric vehicle (EV) drive mileage is dependent on the amount of power available in the battery bank.

A Do It Yourself (DIY) electric car would normally have 15 to 12 units of deep cycle battery. That will provide approximately 50 to 100 driving miles before the batteries have to recharge.

Are there anyways to extend the mileage of an electric car?

The simplest and the most effective way is to maintain a proper air pressure in the tires.

In order to check and maintain the right pressure in the wheel, you will need a tool to assist you. I found a really cool programmable digital tire gauge on Amazon that looks like a device from Star Trek! It’s the Accutire MS-4350B.

The Accutire MS-4350B is a programmable tire gauge capable of reading your tire pressure with exceptional precision. Maintaining proper tire pressure is essential for your safety and extending your EV mileage.

Properly inflated tire can reduce the wheel resistance and reduce tire tread wear. Similar to a conventional car, good tire pressure will increase an EV efficiency.

Tire can lose up to 10 lbs of pressure in the course of a few months. Once they drop 8 lbs below the recommended level, they are considered a safety hazard.

Having a reliable tire gauge such as the Accutire gauge is essential because you can’t tell if the tire is under inflated just by looking at it.

To measure the tire pressure of your electric car, just remove the cap from the tire valve and press the “set” button on the Accutire. A reading of 0.0 psi appears until you place the gauge over and on to the valve.

The digital tire gauge will beep when it has displayed and lock and accurate reading.

The Accutire gauge is also programmable meaning it allows you to record and store the factory recommended pressure of your tire. With that information, you can set the pressure for the front and rear tires.

Because the weigh distribution of your electric car may not be equal due to the placement of the batteries, the programmable feature will come in very handy to determine the exactly pressure for both end of the wheel.

Where can you get the Accutire MS-4350B?

It’s available from Amazon.com with Free Super Saving Shipping. If you are looking for a way to extend the drive mileage of your electric car, get the Accutire gauge today.

Electric Car Conversion – Tackling The Transmission Unit

One of the key areas you want to work on during an electric car conversion project is the transmission. The transmission is a little more challenging.

The transmission was originally designed to coupled to a clutch plate. When you are building a Do It Yourself (DIY) electric car, you are not going to use a clutch. The electric motor will be coupled directly to the transmission.

The main thing the clutch does for a car is allow you to leave the internal combustion engine running when the car isn’t moving. With an electric motor, you can just switch it off.

The other reason you don’t want a clutch is to minimize the amount of mass or the amount of weigh the electric motor has to spin because that will cost you valuable energy.

When the electric motor has to spin a bigger resistant, it will consume more electricity hence making your EV less efficient and it won’t go as far.

When connecting the electric motor to the existing transmission unit, most EV retrofitters will use the Lovejoy metal coupler. Putting the coupler on the motor shaft is easy. But how do you put the coupler on the transmission shaft?

Reason being, the end of the transmission shaft has grooves and teeth while the coupler doesn’t.

To solve this problem, you need to have some creativity and do some modification. You start out by removing the old clutch plate. Look at how the plate is attached to the transmission shaft. You will see a little coupler in it that had ridges that matches up to the shaft of the transmission.

Cut out that small coupler and weld it to the center of the Lovejoy coupler. Make sure the weld is strong so it does not spin. The Lovejoy coupler with the old clutch plate ridges can now be fitted to the transmission shaft. It is a lot of work, but that’s how you solve a problem in a DIY project.

Once you have all the couplers in place and the rubber spider separator in between, you can now connect them together and be able to transfer power from the electric motor to the wheel of your electric car. One of the advantage of the Lovejoy couplers is it allows for a small amount of shaft misalignment.

If your electric motor is not perfectly align with the transmission, it is not going to create much problem. It would not handle too much misalignment though, only one of 2 degree, but it’s better than trying to hard weld two of the shaft together on a straight line. You will never get the line perfect.

How To Extend Your DIY Electric Driving Range With Minimal Cost

In this article, I am going to share with you some important information on deciding your home made electric car driving range needs. You may be asking, why wouldn’t you want the longest drive range possible for your electric vehicle (EV)?

The problem is COST!

Unlike conventional automobile, you can stop by the gas station to refuel and continue driving. Since there are thousands of gas stations around the country, a vehicle using an internal combustion engine has virtually unlimited driving range.

For an EV, the case is very different. A DIY electric car has to carry its power source on board. The power is stored in the deep cycle batteries. To have longer drive mileage on your electric car, you’ll need more batteries.

If you are planning to put extra batteries in your EV, it will inflate your conversion project cost, not to mention the extra dead weight your vehicle has to carry.

The key here is to find the middle ground or the “sweet spot” for your cost versus drive mileage. To determine your EV range, ask yourself the following questions:

1) How far will I need to drive each day?

2) Am I going to use the car for work commute or for unpredictable usage?

3) Is my driving route terrain hilly or flat?

4) Is there a recharging point at my work or at my destination I can use?

5) Is my choice of donor car a big heavy truck, or a small hatchback?

If you’re unsure of the distances, try recording them on your car’s odometer or on a GPS system to give you an estimate. By doing that, you will be able to gauge your daily driving needs.

When you have the figure, you can now design a battery storage system to give you the desired driving mileage for your DIY electric car.
