A buyer’s guide to electric vehicle charging
Most electric vehicle and hybrid car owners choose to buy a charging station for their home, and in this we article will help you to select your own home charging station. There are several factors to consider such as charging speed, installation, location, power adjustment, capacity and size. As well as other important considerations like ease of use and cost.
Generally, there are two levels of chargers that are used in residential settings. These levels directly relate to the amount of electricity each delivers to your vehicle.
Level 1, Mode 1 chargers 0 - 1.9 kW offer the lowest level of electricity, about the same as a standard home socket, and take the most time to fully charge your car. Most Level 1 chargers cannot provide a full charge even when plugged in and charging continuously overnight. For example, a typical Level 1 EV charger adds about 2.5 - 5 miles (4 - 8 km) of range per hour. That means it will take 15+ hours to completely charge a Renault Zoe.
Level 2, Mode 2 chargers 3.7 kW - 11 kW (16 A per phase) are the most practical for electric car owners with limited circuit capacity. They offer a fast charging speed and multiple wiring options (single phase or 3 phase).
Level 2, Mode 3 chargers 3.7 kW - 22 kW (32 A per phase) are ideal for electric car owners. They offer the fastest charging speed, can be configured for single or 3 phase and multiple grid types, and offer many other user-friendly features.
With the Level 2, Mode 3 charger JuiceBox Pro 32 at 22 kW you can charge about 10 times faster than a standard Level 1 charger.

The OLEV Electric Vehicle Homecharge Scheme (EVHS) provides grant funding of up to 75% towards the cost of installing electric vehicle chargepoints at domestic properties across the UK.
From July 2019, only “Smart” chargepoints will be eligible for EVHS grants. By “Smart”, it is meant those chargepoints that can be accessed remotely and are capable of receiving, interpreting and reacting to signals. At eMotorWerks, we have only ever developed smart charging stations , which can be controlled remotely when the grid is under unexpected stress, and we are global market leaders in this sector. The JuiceBox Pro 32 will continue to be eligible for the EVHS grant, under the new conditions which come into force in July 2019.
eMotorWerks’ JuiceBox Pro 32 is eligible for a grant of up to £500 under the OLEV Electric Vehicle Homecharge Scheme (EVHS). The EVHS grant is deducted upfront from the cost of your JuiceBox charger and installation. This guarantees low out-of-pocket expenses.
Simply contact eMotorWerks and we will follow up to help you take advantage of the OLEV grant. We will also introduce you to one of our local approved installers, who will process the EVHS grant application on your behalf.
While many homeowners have carports or garages, some may need to install their charging station outdoors. When buying a charging station, pay attention to its durability while exposed to sun, wind and water. Look for a device that is outdoor rated and select one like the JuiceBox Pro 32, which has IP66 protection rating and features a durable case that is both fireproof and weather-proof.
In most European countries an installation by a certified electrician is required. Contact us and we will connect you to trusted installers from our European-wide network.
Some existing electrical circuits in older homes may need to be updated to be able to support powerful Level 2 chargers. The JuiceBox Pro 32 allows you to set the power level of your device easily direct from the app or web dashboard so that it matches your home electrical wiring capacity.
An added feature of having a smart EV charger like eMotorWerks’ JuiceBox Pro 32 is that it can perform circuit “load balancing” when multiple stations are installed on a single electrical circuit. That means the two (or more) charging stations will be aware of each other’s charging rate and will adjust downward, if necessary, to prevent circuit breakers from tripping.
Some electric vehicle chargers have complicated displays or apps that make it difficult to control or view charging information. With the JuiceNet app (available for iOS and Android), JuiceBox owners can easily view important charging details, schedule or start a charging session, adjust power ratings, set time of use charging, etc. The JuiceBox Pro is also compatible with Amazon Alexa and Google Home, which enables owners to control charging with simple voice commands and to receive status updates on charging.
The JuiceBox Pro 32 is WiFi enabled, which allows you easy access to all of the details and functions of your device from both your mobile phone and your personal computer or tablet. Through the simple and intuitive app and dashboard, you can control everything, including initiating or stopping charging, setting up reminders, charging schedules, and viewing charging history. Everything you need to know about your device is easily accessible from one easy JuiceNet app!
In some areas, electricity rates vary at different times of the day, depending your particular energy contract. As EVs require a lot of electricity, it can be expensive if you charge your car at peak times. However, with JuiceNet SmartGrid EV Charging, your JuiceBox Pro 32 communicates with our servers and charges your car automatically during the off-peak times that you select. This saves you money and reduces stress on the power grid.
If you don’t use a smart charger, your electric car can contribute significantly to more greenhouse gas emissions than it needs to. At any given time, the electric grid is supplied by a mix of electricity from different sources, which include nonrenewable energy (like coal) and clean energy from solar and wind. JuiceNet Green (available in Europe in 2019), a cloud software feature that can be added to a purchase of a JuiceBox Pro 32, is aware of what mix is currently powering the grid and can shift charging time (for instance, from midnight to 2 am when more wind power is available). This maximises charging when more renewable energy is being produced for the grid, greatly reducing the carbon footprint of charging your EV.
Purchasing an electric vehicle is the first step in contributing to an exciting future of innovation and a cleaner environment. Electric cars are continuing to be developed and improved, and electric vehicle chargers are no different. You’ve made the right choice in choosing an electric car, and you should be sure to make a great choice in choosing your charger as well. If you are interested in purchasing our JuiceBox Pro 32, please contact us and we will guide you through all the necessary processes from requesting the grant to the installation.
