Vehicle Integrations –An Ohme Labs feature
Some car manufacturers provide an API (Application Programming Interface) which allows access to
information about your car via your manufacturer’s smartphone app. Providing your login details in
the Ohme app allows Ohme to see your car's current state of charge, which is then used to work out
how much charge you need.
This is an Ohme Labs feature and is currently available for a limited number of manufacturers.
We’re always working to offer the latest in technology to our customers. As a part of Ohme Labs,
we're continuously improving this feature and, from time to time, it may not work as intended.
Please note, certain functionality may also be limited based on manufacturer-specific API
restrictions or limitations. If you have any issues, or you’re worried something just isn’t quite right,
our Customer Care Team are happy to help.

Compliance with Regulations
All ePod units are fully compliant with the Electric Vehicles (Smart Charge Points) Regulations 2021.
These regulations are intended to help the energy sector transition to net zero carbon. EVs can
place new demands onto our electricity system, so as more people make the switch, it is important
that these changes are managed.
Default Off-Peak Charging
When your ePod is first installed, it will not charge during the following times:
•8am and 11am weekdays
•4pm and 10pm weekdays
To change or disable these restrictions, download the Ohme app and pair the charger. You can then
disable these default times and create charge schedules so that Ohme knows when you need your
car to be charged. Once you have set up Charge Schedules, the default times will be automatically
disabled.
Randomised Delay
Many of our customers charge according to off-peak tariffs. When large volumes of chargers
suddenly begin charging at a precise time, it could causes issues for the energy system.
A randomised delay is applied to the start and end of charging times. This delay is initially set to 10
minutes but may be extended to 30 minutes if requested by UK Government. For example, if your
tariff off-peak period is due to start at 00:30, Ohme will apply a random delay to the start time, such
that charging may start any time between 00:30 and 00:40.
Similarly, if the tariff would involve ending the charge session at 04:30, Ohme will apply the random
delay, but this time bring the end time forward to avoid continuing charging into peak periods. So,
your charging would stop anytime between 04:20 and 04:30.
Documentation
A Statement of Compliance is provided at the end of this document to declare that the product
meets these Regulations. A Technical File which describes in detail how we have met the
regulations is available on request.
Security
The secure features of Ohme products are not configurable, they are applied at the factory and
cannot be changed. Ohme maintains a Security Log for each device on the user’s behalf. Please note
that no personal data is stored on the device. Please contact the Helpdesk if you wish to unpair your
device from the Ohme app on your smartphone.
If you have any problems or concerns around security or regarding the vulnerability to cyber-attack,
please report this to the Helpdesk.

Installation
At a glance…
•Ohme units have PEN fault detection
•The RCD inside the unit is Type A and 6mA DC
•The units use the 4G mobile phone network, it is preconfigured to connect to the
Ohme backend server automatically
•Load balancing can be setup with the current sensor (CT) clamp
Mounting the unit
The Ohme ePod is designed to be wall mounted to a flat surface. Fixings are included which are
suitable for most wall surfaces (e.g. brick/render) but the installer should select their own if these
are not appropriate.
Use the drill template provided with a 7mm masonry drill bit. Mount the rear of the ePod using four
screws. Where the surface is uneven, it is essential that the rear of the ePod is not twisted when
secured to the wall. It may be necessary to add spacers between the unit and the wall to avoid
twisting the unit, otherwise the unit may not seal correctly.
To avoid breaking the plastic screws, do not use a power tool when securing the front to the rear.
Check there are no gaps around the join line that could allow water ingress. Finally, attach the
rubber covers to the front plastic screws.
Electrical connection
The overall installation must be compliant with the IET Wiring Regulations and the IET Code of
Practice for Electric Vehicle Charging Equipment. Installation should be carried out by a competent
electrician with knowledge of EV charge point installations.
The ePod has a terminal block for Live, Neutral and Earth. The terminal block can accept a 6mm2
conductor. There are cable entry points at the bottom and rear. A 25mm gland and a blanking
grommet is provided. The blanking grommet is attached to the rear entry hole. If feeding the cable
in from the rear, it will be necessary to move the grommet to the bottom.
Installer Mode
On first power up, the ePod will be in installer mode allowing the setting of the maximum rating,
enabling load balancing and the setting the fuse rating using the buttons. See the ePod Quick Set Up
Guide. However, we recommend that the Ohme Installer Web App is used. Contact the customer
care team at [e-mail] to get set up.

RCD
The Ohme ePod has a Type A 30mA and DC 6mA RCD built in. To avoid blinding of RCDs, we
recommend that any upstream RCD is at least Type A. Type AC RCDs may saturate and fail to
operate in the presence of smooth DC currents below 6mA.
In the event of an RCD activation in the Ohme charger, the unit is reset by power cycling (switching
the supply off, wait 5 seconds, and switch on) or by unplugging and re-plugging the vehicle. The RCD
in the unit is certified as an RCD-DD, conforming to IEC62955.
Earthing Arrangement
The ePod has an in-built PEN fault detection function, as described in 722.411.4.1 (iv) of the Wiring
Regulations 18th Edition, to disconnect the vehicle from the live, neutral and earth conductors if the
voltage is greater than 253 V and less than 207 V. The units can therefore be connected to the PME
on TN-C-S single phase supplies.
Overcurrent Protection
No overcurrent protection is provided in the Ohme ePod, separate provision is to be provided as
part of the installation. We recommend a 40A Type B MCB.
Installing the CT Clamp
The Ohme ePod has a dynamic load balancing feature. A current sensor (CT) clamp is provided to
measure the electrical demand of the property, or sub-board. The unit will limit the maximum
current available to the vehicle to keep the household demand below the set threshold/fuse value.
We recommend installing the clamp regardless of whether load balancing is needed as it future
proofs the installation for advanced features, such as solar.
The unit is designed to comply with the relevant parts of Engineering Recommendation (ER) G100,
which is a requirement of some DNOs to permit installation in circumstances where the property
has insufficient capacity.
Once load balancing is activated, if the CT clamp is removed, or is faulty, the unit will revert to 16A.
It is therefore sensible to ensure the spare capacity, after taking account of other loads and
diversity, is at least 16A.
Note: where the dynamic available capacity for the charger drops below 6A, the ePod will pause the
charging for at least five minutes to prevent rapid switching of the vehicle where the current is
hovering above and below the threshold.
Ohme units calculate the direction of the current automatically after the first charging session. The
clamp can be installed in either direction.
Spring connectors are provided on the circuit board to attach a cable used for connecting to the
clamp. The spring connectors will accept a maximum 1.6mm2conductor size.

Figure 1 –Clamp connection using spring connectors
Connect up the CT clamp and follow the commissioning procedure either using the Web App or on
the unit using the buttons:
•Web App: once the CT clamp is connected, click Check Clamp to check for correct
connection. Click Enable Load Balancing, then Save Settings
•Buttons: see the ePod Quick Set Up Guide provided in the box. During the clamp check
process, the LED light bar will turn from red to amber when a clamp value has been
successfully received.
The CT clamp and wiring is not polarity sensitive –you can install the CT clamp in either direction.
Ohme recommends EV Ultra Cable 3 Core + Data as a convenient single cable solution. This cable
contains two data cores and can be used to extend the clamp cable up to 60 metres. Cat5e Ethernet
cables or alarm wire (e.g. Belden) can also be used to extend the CT clamp.
There are two marked areas for drilling to install a separate gland, suitable for a M12 or M16 gland.

Network/Internet Connection
The Ohme ePod uses a 4G data connection which is pre-configured in the factory to communicate
directly to the Ohme backend server.
Signal coverage in the UK is generally very good but it is important to ensure the customer is aware
that the unit relies on a mobile signal. Where it is known to be unreliable, the customer should be
made aware that the smart features of the Ohme unit will also be unreliable. Ohme cannot be held
responsible for the installation location and issues with the public mobile phone network.
Where the unit cannot establish data transfer at the time of plug in, the unit will behave like a dumb
charger and will not schedule the charging session.
