When is the new software app coming out for the Smart Splitter?

We are excited to bring to you a brand new look and feel to our app experience coming the beginning of next year. Currently, the app is in its core BETA testing stages of the app development and our engineering team is working around the clock to build out a completely new app experience for each of you. This new experience will be brought to you by an over-the-air update because of the WiFi-enabled features in the 240v Smart Splitter.

As of right now, the beta group for our software is oversubscribed and we are not able to accept any more users. Beta-users, please bear with us if there are any issues with the current BETA version of the mobile app as we progress on this new app experience.

Your Smart Splitters core functionality works as promised, so feel free to use the device as originally intended and we will reach out as soon as the new app is ready.

What do I do if my dryer, or 240v outlet, isn't in or near my garage, can I still use the Smart Splitter?

The brief answer is, yes. We're here to help as many people as we can, but in reality, the Smart Splitter solution really depends on the way your home was built and what region you live in. In many homes throughout California, Washington, Florida, Texas, and many other states, it makes a-lot of sense to be split a common 240V outlet, such as a dryer circuit, in or near the garage to share power between your appliance and EV. Colder regions in North America, such as the Midwest, have 240v outlets installed in other areas of the house, like the basements, much farther from where they'd charge their car. The Smart Splitter would only make sense for those individuals who are able to use a high quality 240V extension cable, UL rated, through a third party seller, however we are working on other solutions to provide you with cost effective EV charging access.

We designed our Smart Splitters with an intention to be compatible with all 240v appliances and outlets, so 240v dryers aren't the only thing to look for when identifying if this solution would work for you; check to see if you have an electric water heater, AC 240v outlet, electric range, etc. In the event that you did install a dedicated 240v outlet in your garage, you have the ability to future proof your home by installing a Dual-EV Smart Splitter and share one outlet between two chargers. While it may not work in all areas. In the areas it does work for this can save a lot of money on electrical work.

Why is the Smart Splitter priced the way it is?

There are multiple factors that play into the Smart Splitters price point. First off, we hold a high standard for the materials we used to design and build the Smart Splitter; the entire device is enclosed in a high-quality heat resistant Bayblend FR3010 plastic exterior, UL rated NEMA receptacles, and high-grade circuitry made to withstand an immense amount of stress and electrical current. Next, safety is the #1 priority for us here at NeoCharge, prompting us to go through a year and a half of testing with trusted experts from Underwriters Laboratory (UL), collaborating to make crucial design changes, ultimately resulting in us being the only 240v circuit splitter awarded with the highest safety certification possible in industry. UL has been around for over a century and wrote the vast majority of the current industry safety standards, and having their stamp of approval aligns us with industry-wide best safety practices. Lastly, each Smart splitter is assembled with care, by hand, on the Central Coast of California, making sure every device is built just right for every customer.

The 240v Smart Splitters enable homeowners and renters, like yourself, to utilize existing 240v infrastructure to gain the fast charging access you need to charge your electric vehicle at home.  We understand for some, installing a dedicated outlet might be an option, however for homes that do have additional capacity, adding another dedicated circuit can be expensive too as the run of new electrical wire may be long, drywall patching, permits, plus time and materials add up. Check out this informational blog "How much does it cost to install a home charging station?" to learn more about what all goes into installing home EV charging.

More importantly, for all renters, they don't have an option to make any structural changes whatsoever, and for the majority of homeowners they would need to upgrade their entire service panel (breaker) in order to have sufficient capacity to add a dedicated 50amp outlet to charge your car. For example, many homes have a 100amp or 125amp main service panel, whereas adding another 50 amp circuit will exceed the main panel capacity, ultimately costing several thousands of dollars for installing a new panel and dedicated outlet. Currently, many of our customers are saving an immense amount of time, and upwards of $1,000 - $2000 avoiding a panel upgrade or costly installation in general.

We were awarded $150,000 in grants by CALSEED, through the California Energy Commission (CEC), to construct a software platform and app that enables existing 240v Smart Splitters the ability to utilize cleaner and more affordable energy consumption. In future releases, we are expecting to provide advanced scheduling, rewards for charging ,and more enhanced features that will continue to save you money every month. Over the past six months, our teams have been working nonstop to build out this solution for all of our amazing customers.

I have a dryer circuit in my garage but isn't it dangerous to draw that much power through a single 240V outlet?

Safety is our top priority at NeoCharge, therefor all 240V Smart Splitters have built-in safety mechanisms to ensure you are never pulling more than what the circuit can handle. The way this works is through our automated power switching using an outlet priority system. To put it simply, the primary outlet (left side) takes priority over the secondary (right side), and whenever the primary outlet requires power, the device will automatically prioritize that device to charge first.  The most common case here would be your appliance plugged into the primary and your car plugged into the secondary.

Here is what the smart switching looks like: First, you're charging your EV. Then when your dryer starts, the Smart Splitter automatically pauses the EV charger. When the appliance cycle is finished, the EV automatically resumes charging. All this is done automatically without requiring any user intervention. This ensures you don’t need to worry about overloading your circuit or plugging and unplugging your devices.

How do I know what kind of 240v outlet I have and which kind of Smart Splitter I need?

Installing Charging Access With a NeoCharge Smart Splitter

Step One: Identify your existing 240v wall socket.

Step Two: Match your wall socket type with the matching Smart Splitter receptacle.

If the plug on your EV charger looks different than the outlet in your wall (commonly seen in older appliance types), you can add an adapter to any order. Because safety is our top priority at NeoCharge, based on UL safety requirements, the Smart Splitter is required to have the same outlet type on both outputs and inputs.

For example, if you have have a dryer that plugs into an existing NEMA 10-30 outlet, and an EV charger with a NEMA 14-50 outlet prong, you would purchase a NEMA 10-30 to NEMA 14-50 adapter to allow your charger to be compatible with the NEMA 10-30 Smart Splitter your setup requires.

Step Three: Choose the Smart Splitter that works best for you!

Types of Electrical Outlets For Electric Car Chargers

What is the NeoCharge Smart Splitter, how does it work, and why does it exist?

What is the Smart Splitter?

The Smart Splitter is a compact (5.25" x 5.25" x 2.8"), portable device that allows you to intelligently and safely share an existing 240v outlet for charging two electric vehicles, OR, share full power of an appliance (such as a dryer, water heater, or stove) and an EV using the same 240-volt outlet. The NeoCharge Smart Splitter is the only 240v circuit splitter awarded with the highest safety certification possible in industry: UL. On the left side of the Smart Splitter there’s a “primary” outlet, and on the right side there's a “secondary” outlet. In most cases, the dryer (or alternate electric appliance) gets plugged into the primary outlet (left), it gets power whenever you need it and will pause power going to the secondary outlet as the primary outlet always takes priority. The secondary outlet is most commonly occupied by an EV charger, but it can also be used for a second electric appliance.

How does it work (Appliance + Dual EV)?

The Smart Splitter functions in the same way that you're used to an outlet working, but with intelligent load sensing. If you get home from work and plug in your EV to charge, your EV will begin to charge. if you need to start a load of laundry an hour later, simply load up your dryer and start the cycle. Your Smart Splitter will identify a change in current draw and pause your EV charge to allow your laundry to dry. Once your laundry is done, your Smart Splitter will switch over and let the car resume charging through the secondary outlet again. Thus, you can now effortlessly share  power between your dryer and EV and ensure your outlet is never overload. Everything is handled automatically with a proprietary switching algorithm—you don’t have to program the Smart Splitter, it just works.

Additionally, the Dual-EV Smart Splitter (NEMA 10-50, 14-50) allows for simultaneous charging. Most EV chargers and electric cars allow a current limit to be set for charging. By setting the current limit on both of your chargers or EVs to add up to the maximum amount of power your outlet can deliver, the Smart Splitter enables you to safely share power between both outlets at the same time. For example, if you own two Teslas and have one 50 amp circuit, set the current rate on both vehicles to 20 amps and let the Smart Splitter do the rest. If the total power draw ever exceeds the rating pf your outlet, the Smart Splitter automatically shuts off power drawing to the secondary outlet. This example also illustrates what it looks like to share two appliances with your Smart Splitter. As long as the total power draw doesn’t go over your outlet’s rating, any pair of 240v devices can run at the same time on the same outlet (i.e. a water heater and a dryer). This switching and splitting technology has been approved by UL, and is what ensures you, your house, and your family are safe when using the Smart Splitter.

According to the US Department of Energy, over 80% of EV charging happens at home, where EV owners have set up their own chargers. The key is, the Smart Splitter can eliminate the need to install a dedicated circuit or upgrade your electric panel which can cost thousands of dollars depending on your setup. Your Smart Splitter is able to be self-installed, no electrician needed, which saves you time and money on installation.

Can I mix and match inputs and outputs on the Smart Splitter? If no, can I use a NEMA plug adapter for my EV charging setup?

We don't offer custom outlets at this time, but feel free to visit our products page to add a high-quality adapter if your EV charger plug looks different than the outlet in your wall (usually for older appliance outlet types).

Because safety is our top priority at NeoCharge, in order to comply with the highest safety standards and Underwriters Laboratory (UL), the input and outputs (outlets) on the NeoCharge itself cannot be mismatched. If your wall outlet is different from your EV charger, you can order a high quality NEMA adapter to go from a NEMA 14-50 to NEMA 10-30 or to go from NEMA 14-50 to NEMA 14-30.

For example, if you have have a dryer that plugs into an existing NEMA 10-30 outlet, and an EV charger with a NEMA 14-50 outlet prong, you would purchase a NEMA 10-30 to NEMA 14-50 adapter to allow your charger to be compatible with the NEMA 10-30 Smart Splitter your setup requires.

How much does it cost to have an electrician install a dedicated 240v EV charging outlet in my home?

Ultimately, the cost to install a home charging station varies on a number of determining factors. The age of the home, the electric panel capacity, the type of installation, and where the panel location is relative to the car charger all play a role in the total cost. For many, upgrading the entire service panel is required in order to install an additional dedicated 240v outlet for EV charging. However, by sharing an existing 240v outlet between two devices (like a dryer and an EV charger), it's easily possible to save thousands of dollars on installation costs.

Below is a table that breaks down various costs that go into installing home EV charging.

What outlets and 240V circuits is the Smart Splitter compatible with?

How are you able to charge two cars simultaneously using one 240V outlet?

In order to charge two EVs simultaneously, you'll need any EV charger OR any EV that support setting a current limit. For example, on a 50 Amp circuit you safely pull up to 40 Amps of continuous power. This means you can set the current limit on your car/charger(s) to charge both cars at 20 Amps (or any combination summing to 40A i.e. 30A + 10A), and your Smart Splitter will intelligently balance power between the two devices. As an added safety feature, if the total power ever exceeds 40 Amps, your Smart Splitter will sense this and shut off your secondary charger or device.

What's the difference between Level 1 charging (110V) and Level 2 (240V)?

Each level of charging is defined by the amount of voltage, which directly correlates to the speed or quickness of the charging session. Level 1 (120V) is the slowest, followed by Level 2 (240V).

Level 1

Level 1 utilizes a 120V outlet, which is the standard residential outlet for nearly all of your everyday devices such as refrigerators, TVs, or even your phone. This level of EV charging is only found at residential locations. In fact, Level 1 charging is routinely known as “trickle charging” due to its slow speed.  A typical EV can recharge around 4 miles of range per hour with Level 1 charging. 

Level 2

Some would argue that Level 2 charging is the best option for charging at home. In residential applications, Level 2 charging utilizes a 240V outlet. This makes it much quicker than Level 1. With double the voltage, a 240V outlet is typically used with high-powered appliances such as an electric dryer, water heater, or range. Level 2 charging provides around 12-30 miles of range per hour. To fully recharge an all-electric car will take around 6-12 hours depending on the battery size. 

Since electricity rates are cheaper overnight and since you sleep at night, Level 2 charging is really convenient for your wallet and your time! Charging your car at home is like having a gas station at your house--think of all the time you would save. Plus, every day you wake up the EV is charged to 100% leaving you free of any range anxiety. 

Unfortunately, most garages do not frequently have a spare 240V outlet, unlike the Level 1 120V outlet. Therefore, an electrician is needed to install the new, dedicated 240V outlet. In some events, the electrical panel may need to be upgraded. All of this can cost upwards of $2,500 for a panel upgrade. 

Fear not! If there is a 240V outlet in the garage that is currently occupied by another appliance like the dryer, you can simply plug in the Smart Splitter to unlock two 240V outlets from one. The Smart Splitter was created to automatically switch power to the device in need and, most importantly, can save you hundreds, if not, thousands of dollars from unnecessary electrical work. 

Why is it unsafe to use a basic Y-splitter cable to share an EV charger and dryer on one circuit?

The biggest problem is safety! Since both outputs of the cable are considered active at all times, if both devices plugged in are being run at the same time, there is a likely chance you will overload the circuit. Overloading the circuit can cause the wiring in your home to overheat and cause a fire hazard.

NeoCharge's founders discovered this to be a major problem for homeowners, and wanted to provide an alternate solution for EV drivers to still utilize their existing 240v sockets in their home. Hence, the creation of the NeoCharge 240v Smart Splitter - the safest 240 socket splitter.

Does the Smart Splitter work in Europe or the UK?

NeoCharge's Smart Splitters are currently only available in North America (i.e. US and Canada) where there is a standard for NEMA 220v/240v outlet types.

For Canada specifically, you can purchase here on our website or directly from our partner Sun Country Highway.
