HOME ELECTRIC CAR CHARGER

Save money:If you have a time-of-use tariff or a variable tariff, you’ll pay less for your electricity at certain times of the day. The Ohme app uses your tariff information to charge as much as possible when the price is low to maximise your savings.
Remote management:With the Ohme app, you can control your charging at the click of a button. You can schedule charge sessions, apply a price cap to limit your charging to a certain price/kWh, and keep an eye on your energy costs & consumption.

Grid balancing:The Ohme charger can adjust energy intake according to peaks and lows in electricity demand which allows for load balancing and peak shaving. Put simply, peak shaving refers to managing consumer demand to eliminate demand spikes (high peaks) which in turn puts less pressure on the grid. This is often done through energy suppliers offering cheaper electricity during off-peak hours.

You’ll need to create a schedule that specifies the percentage you would like to add to the current amount of charge displayed in your car.

For example, if you normally return home with 30% charge left in your EV and you want to have 80% ready for the next morning, you’ll need to create a schedule to add 50% more charge (30% + 50% = 80%).

If you create a schedule asking Ohme to add charge more than 100%, you might receive an alert to tell you that your car isn't charging as expected. This isn't anything to worry about, but it's our way of letting you know that we were expecting to deliver more charge.

If you have any issues, or you’re worried something isn’t quite right, our Customer Care team are happy to help.

There are a number of things that can affect how long it takes to fully charge your EV. The charge point directly affects the rate at which your car charges as it will have a maximum charge rate it can deliver. The time it takes to charge is also affected by car battery size, battery state of charge, and environment (such as how cold it is outside). This might all be new to you, but we’ll explain a little bit more about how these factors impact how long it takes to fill your battery.

Battery Size: Some cars have larger batteries than others, and these will take longer to fully charge. If you have a plug-in hybrid with a smaller battery, you’ll notice this take much less time to full charge than a fully electric car.

Maximum charge rate of vehicle: Your EV will have a maximum charge rate which effects how quickly the battery can accept charge. If your car has a maximum charge rate of 7kWh, this means it’ll only be able to consume 7 kilowatts of energy every hour. You can use your car’s maximum charge rate and battery size to work out how long it may take to fully charge.

Maximum charge rate of charge point: Each charge point has a maximum charge rate, which may differ from the max charge rate of your car. Your car may have a maximum charge rate of 7kWh, but you’ll notice the car charges much more slowly when plugged into a 3-pin charger with a max charge rate of 2.4kWh.

Temperature: Colder temperatures can cause longer charging times, but you’ll probably only notice this when rapid charging. A cold battery will take a little longer to ramp up to 200kWh, but shouldn’t have any trouble charging at 7kWh in colder weather.

State of battery: The closer your battery is to empty, the longer it will take to charge. Make sure you allow plenty of time to charge if your battery is particularly low.
