Product overview
Ohme Home
Ohme Home is an Electric Vehicle (EV) charging device to be used with single phase
electricity supplies (which is standard in most UK houses). It's a tethered unit, which
means the cable cannot be removed. It has a maximum charge rate of 32 A.
V2.0
Page of3 30
32A
7.4kW
The battery capacity of your EV will determine how long it
takes to charge. To get an estimation of how long your EV
will take to charge from 0 - 100% (When charging at your
charger’s maximum rate) divide the battery capacity by the
charging power.
For example: 60 kWh / 7.4 kW = 8.1 hours
Tip:
Ohme Go
We have a range of Ohme Go chargers with dierent plug types: Commando, Type 2, 3-
Pin, Schuko / European Charger.
Please do not use multi-plug adaptors or extension leads with any Ohme Go charger.
Many of these are not suitable for the continuous, high loads drawn by electrical vehicle
charging, nor are they suitable for use outside.
Commando
Our Commando charger is designed to be used with a 32 A CEE "commando" socket.
Your electrician will be familiar with these sockets and the additional requirements for
using them to charge an electric vehicle. You will nd all of the relevant information for
installing a Commando socket to use with a Commando charger in the 'Commando
socket installation’ section on page 27.
The Commando charger will charge at a maximum rate of 32 A. If you're unable to charge
at 32 A due to supply limitations, just call us and let us know the serial number of your
charger and we can remotely reduce the charge rate for you.

32A
7.4kW
Type 2
Our Type 2 charger is designed to be plugged into your existing un-tethered charge
point. No additional installation is required, simply plug in your new Type 2 charger and
download the Ohme app to start benetting from Ohme's smart features.
The Type 2 charger will talk to your charge point and make sure that it does not charge
above the rating of your unit. If you have an existing 16 A charge point, Ohme will charge
at a maximum rate of 16 A (there's no need to contact us to reduce the rate).
Your Type 2 charger can charge up to a maximum rate of 32 A, if not limited by the rate of
your existing untethered charge point.
IMPORTANT NOTE: the Type 2 charger won't power up unless it's plugged into both a
power supply and an electric vehicle.

3-Pin
Our 3-pin charger can be plugged into a standard UK socket. We recommend that you
ask a qualied electrician to give your electrical supply a once over, just to make sure that
the socket and circuit are safe for the continuous demands of EV charging.
Although UK 3-pin plugs are rated 13 A, most domestic sockets can't safely deliver this
current for long periods of time, so to avoid the potential for overheating we've de-rated
our cables to 10 A.
For daily charging, and to reduce the risk of overload to existing electrical systems, you
can ask a qualied electrician to install a dedicated external socket.

2.4kW
Schuko / European Charger
Our Schuko charger can be plugged into a standard European socket. These are rated at
13 A, so it's important to ask a qualied electrician to check that the supplying circuit and
socket are safe to deliver 13 A for the duration of your charge.Charging at 13 A can
provide about 10 miles of added range an hour.
For daily charging, and to reduce the risk of overload to existing electrical systems, you
can ask a qualied electrician to install a dedicated external socket.

Ohme box overview
The control box is identical across all variants. The LCD display has various icons that tell
you important information about the charger, as well as useful real-time measurements of
active charge sessions. The circle of indicator lights provides a visual reference to the
current state of the charger. More information about the indicator lights can be found on
page 11.
Don't worry about your charger being left outside, it's IP55 rated which means it's
resistant to all weather types.

‘Pair’ your charger
When prompted, use your camera to scan the QR code

need to allow access to your camera for this). This will
link the charger to your Ohme account.
If you're having trouble scanning your QR code, you can

manually' in the top right of your screen.
Select your car
Next, you need to tell Ohme which car you drive so
we can accurately calculate your charge sessions.

'Account Sign In' option where you'll be
prompted to log in with your car
manufacturer app's login details. This gives
Ohme access to your car's state of charge.
This option is currently only available for
select manufacturers. To check the current
list of available manufacturers, please visit
our website.
You can change your car at any time by
heading to ‘Settings’ > ‘Change Car’ and

Tip:
If you can't see your car listed, please contact our Customer
Care Team so we can add this to the database for you.
Select your tari
Choose your energy supplier and tarifrom the list
provided. If you have a variable or time-of-use tari, we
can use this information to save you money by charging
at the cheaper rates. If no taris are listed once you've
entered your postcode, get in touch with our Customer
Care Team who will be able to help.
Can't see your electricity supplier or tari
listed? You can create a custom tariby
selecting the 'Create New Tari' option
located at the bottom of the ‘Select
Electricity Supplier’ list.
If your tariis a single price throughout the
day and night, choose ‘Fixed price tari’. If
your tarihas an o-peak period, choose
‘Variable price tari’.
V2.0

Create your schedule
Create a charge schedule to ensure your car
has exactly how much charge you need,
when you need it. You can create as many
charge schedules as you like, and Ohme will
pick up whichever schedule is applicable at
the time of plug-in. For example, you could
create a charge schedule for 70% by 7am
every weekday, and another for 100% by
10am every weekend.
If you want to check which schedule has
been applied while charging, take a look at
the main dashboard where you'll notice the
name of the schedule is displayed
underneath 'Smart Charging’.
Lock your charger
If you want to securely disable use of your charger you
can create a ‘Lock’ schedule. Tap the ‘+’ button located in
the bottom right of the ‘Charge Schedule’ section of the
app. Tap the days you wish the schedule to be active and
set the ‘Target/Added Range’ to 0%. Set the ‘Finish Time’
for just before you are due to arrive home at the end of
the day.
For example: If you are regularly away from home until
6pm each night you could create a ‘Lock’ schedule with a
‘Finish Time’ of 5:30pm. If anyone plugs in before 5:30pm
the ‘Lock’ schedule will be applied and zero charge will
be added to the car.Plugging in after 5:30pm will set the
next active schedule.
