Splitvolt Splitter for EV

Last updated May 15, 2022

What if you had two electric vehicles and you don’t want to install two circuits because It could be expensive?

What the Splitvolt circuit splitter does is it allows you to charge your EV from an existing electric dryer outlet.

You can get this splitter, plug it into the 240-volt outlet and plug two EV chargers in and charge both cars.

Home Charging

Before we get into exactly what the Splitvolt splitter does, let’s first briefly explain home EV charging. There are two types of charging you can do at home or two levels: Level 1 and Level 2.

Level 1 Charging

Level 1 charging is when you charge your electric vehicle from a regular 120-volt household outlet, you can charge any electric vehicle from a simple household outlet. It’s going to take a long time because a household outlet doesn’t deliver that much energy.

In fact, you only get somewhere between three and five miles of range for every hour when you’re plugged into a regular household outlet on your electric vehicle.

Level 2 Charging

When you upgrade to Level 2 charging, you use a 240-volt outlet. Charging from a Level 2 240-volt outlet with a charging station like the ChargePoint Home Flex, the Tesla wall charger or the Grizzl-E charger, you can charge your vehicle much faster all the way up to 45-50 miles of range per hour.

That’s why people might want to invest in a Level 2 charger for their car. They’ll recharge their EV that much faster, which makes EV ownership much better.

About Splitvolt Splitter

Save Money

Splitvolt made this splitter to save EV owners a lot of money and make home charging a lot less painful.

Now many people get their EVs for many reasons, but quite often, it’s to save money. Electric fuel costs a lot less than gasoline does.

However, if you have to spend thousands of dollars to install a home charger, a lot of your savings go out the window. So what the folks at Splitvolt did was they came up with the power splitter that allowed electric vehicle owners to utilize an existing 240-volt outlet that’s currently being used for something else like an electric clothes dryer.

You place your clothes dryer in your garage or very close to your garage where you can use an extension cord and charge your vehicle from the charger.

Most electric clothes dryer outlets are on a 30-amp circuit. You would plug the Splitvolt into the existing dryer outlet, then plug the dryer into one side of the Splitvolt which is labeled dryer, and you plug your electric car charger into the side that says EV.

What the splitter does is it intelligently splits the power. It will allow you to use your dryer and have your electric car plugged in, and it will switch back and forth when the dryer is finished, the electric car charges.

It’s not going to be for every electric car owner. For instance, you just bought a Porsche Tycoon, and you probably won’t use the Splitvolt splitter because you’re probably going to spend whatever it takes to fit your garage out to have the proper charger. It doesn’t matter if you have to spend two or three or four thousand dollars to put a charging station in your garage. You have the money for it if they just dropped 200k on a car.

However, many people are budget-minded and would rather not spend the money unless they have to.

Installing an outlet in your garage to plug your Level 2 charger in can be as little as $300. If you have a very simple installation, like your service panel isn’t far away, and you have the additional capacity in your service panel to put a dedicated 30, 40, 60-amp circuit, it minimally costs three or four hundred dollars to get one of these installed.

However, many people spend a lot more money when they try to have one of these installed. It depends on how far your service panel is. If your service panel is down in the basement 100 feet away, that’s a lot of cables to run, so the installation can easily creep up over a thousand dollars just for the outlet. It gets even more complicated if you need to have a service upgrade. So is there any way you can utilize what you have?

The answer is YES. The Splitvolt splitter allows you to provide the location of the existing dryer outlet that you have, or there could be an outlet in your garage that the previous owner used for welding or a number of uses. That’s being used for another appliance, and you could share that circuit. All of this will allow you to forego any installation expense. The only thing you have to do is buy the splitter, plug it in and get a charger to plug in.

Safe Charging

The Splitvolt splitter won’t allow the circuit to draw more than 24 amps. If at any given time, it’s drawing more than 24 amps, the current protection will shut off, and it will stop working.

The Splitvolt allows an extra level of protection, so you won’t overdraw your circuit if you’re using a charger that can deliver more than 24 amps.

You will want to reduce the maximum charge rate inside the vehicle. Most electric vehicles allow you to do this.




Typical Splitvolt Installation Using A Dryer Outlet

  1. Plug in and turn on the power to the Splitvolt splitter switch. It includes real-time power status display and monitoring.
  2. Plug in the charger handle to the vehicle. Charging begins automatically. The charging rate increases gradually until it is charging the EV with full 24-amp power.

When the dryer starts, EV charging is automatically switched off until the dryer is no longer in use; when the dryer completes its cycle or is turned off, EV charging resumes automatically.




The Splitvolt splitter comes with a three-foot pigtail which is important. Because sometimes you might have to reach down low behind your electric dryer. It’s also important because some NEMA outlets don’t have a standard orientation, and sometimes they’re installed with the ground down, sometimes with the ground up. You would order your Splitvolt splitter with a plug that matches the existing plug that your electric dryer uses.

EV Charger

Splitvolt also sells EV charging equipment that you can pair with the Splitvolt circuit splitter. You don’t need to use their equipment, and you can use any EV charger provided on the market. The Splitvolt splitter comes with a variety of different plug configurations, so make sure that

  1. You choose the right dryer plug based on which plug your dryer has.
  2. Which receptacle that your EV charger will plug into.

If you don’t have any charging equipment and you order it all from Splitvolt. That’s an easy thing to do because you go to Amazon. You just make sure that you get one that’s configured with the right plug for your Splitvolt splitter.

Splitvolt offers their chargers in three different plug configurations so you have to make sure to match the configuration on your Splitvolt circuit splitter.

They have a NEMA 10-30 plug and a NEMA 14-30 plug, both of which can deliver 24 amps for the vehicle. They also offer one with a NEMA 14-50 plug which can deliver up to 40 amps to the vehicle.

If you do buy this unit, you have to make sure that you dialed back the amperage that your electric vehicle accepts because you don’t want to exceed the 24-amp limit that the Splitvolt circuit splitter is capable of delivering.

In Conclusion

The Splitvolt will be typically installed on a 30-amp circuit which is what electric dryers are on now. Even though it delivers a little bit less power than what some of the other higher powered EV charges do, you’re going to be saving a lot of money, and you don’t have to go through the hassle of calling an electrician pulling permits, spending the money on an extra circuit, perhaps even a service upgrade.

The Splitvolt comes with a one-year manufacturer’s warranty.

If you are interested in the 24-amp chargers made by Splitvolt, you can also check the details on Amazon. Just like the Splitvolt splitter, they come with different plug configurations, so it’s really important that you match your Splitvolt and your portable charger with the proper NEMA plug configuration.
