Where standards or regulations are mentioned, you must comply with the most current edition at the time of the installation. In cases of apparent inconsistency, the IETthe [IET Wiring Regulations (BS(BS 7671:2018+A1:2020)A1:2020 take) take precedence for electrical installation requirements.

Installation

This specification is for the charging equipment only and not the final installation.

But you must carry out the final installation in accordance with:

• IET Wiring Regulations - (BS 7671:2018 if installed before 31 July 2020 or BS 7671:2018+A1:2020 if installed after 31 July 20202020)
• the recommendations of the IET Code of Practice for Electric Vehicle Charging Equipment Installation

Data requirements

Each chargepoint outlet must measure energy supplied and output this both to:

• the display (where fitted)
• a data acquisition system compatible with OZEV chargepoint usage data requirements

If you’re using an electricity meter that is not approved under the Measuring Instruments Directive (MID), you must provide details of metering and accuracy.

Data you need to provide to OZEV

As a grant recipient, you must make appropriate arrangements with your chargepoint operator(s) to collect and submit data on each charging event under each of the following data headings:

• chargepoint ID
• plug-in date and time
• unplug date and time
• charge start date and time
• charge end date and time
• total energy drawn (kWh)

The definition of each data field can be found in Data field definitions.

All data points should be recorded at greater than 95% accuracy.

OZEV will accept data supplied from units that record energy consumption at intervals of up to a maximum of 30 minutes.

Data field definitions

Data field	Description
Identifier for chargepoint	Unique identifier for chargepoint. This should match the chargepoint ID used on all forms and claim forms, and be consistent throughout the life of the chargepoint.
Plug-in date and time (dd/mm/yyyy) (00:00h)	The date and time that the vehicle was plugged in, in 24-hour clock format and using the UK (not US) date format, expressed to the nearest minute possible. OZEV will accept data supplied from units that record connection/disconnection at intervals of up to a maximum of 30 minutes.
Unplug date and time (dd/mm/yyyy) (00:00h)	The date and time that the vehicle was unplugged, in 24-hour clock format and using the UK (not US) date format, expressed to the nearest minute possible. OZEV will accept data supplied from units that record connection/disconnection at intervals of up to a maximum of 30 minutes.
Charge start (dd/mm/yyyy) (00:00h)	The date and time that the vehicle began to draw charge, in 24-hour clock format and using the UK (not US) date format, expressed to the nearest minute possible. OZEV will accept data supplied from units that record energy transfer at intervals of up to a maximum of 30 minutes.
Charge end (dd/mm/yyyy) (00:00h)	The date and time that the vehicle stopped drawing charge, in 24-hour clock format and using the UK (not US) date format, expressed to the nearest minute possible. OZEV will accept data supplied from units that record energy transfer at intervals of up to a maximum of 30 minutes.
Total energy drawn (0.00kWh)	The electrical energy transferred during the charging event, in kWh, rounded to 2 decimal places, and with energy transferred from the charging point to the vehicle being positive and energy transferred from the vehicle to the charging point being negative. If this is not directly measurable and you wish to infer this from other parameters, please contact OZEV to discuss exactly how you propose to estimate the energy transferred.

How to provide data to OZEV

Format

You must supply data to OZEV in an Excel (.xslx) file in the following format:

Charging event	Chargepoint ID	Plug-in date	Plug-in time	Unplug date	Unplug time	Charge start date	Charge start time	Charge end date	Charge end time	Total kWh
20	WMP11418	03/03/2016	15:54	03/03/2016	20:05	03/03/2016	15:54	03/03/2016	16:46	2.83
21	…	…	…	…	…	…
22	…	…	…	…	…	…

The grant requires that you provide this data set to OZEV quarterly by emailing chargepoint.grants@ozev.gov.uk.

For OZEV to amalgamate the data efficiently:

• the subject header for emailed submissions must be in the following format: ‘YYMMDD – WCS CP usage data – Chargepoint operator name’
• the Excel file containing the data should be named using the following format: ‘YYMMDD – WCS CP usage data – Chargepoint operator name’

How often you need to provide this data

You must provide data as follows:

• 1 April – data submitted for January to March
• 1 July – data submitted for April to June
• 1 October – data submitted for July to September
• 1 January – data submitted for October to December

You need to provide data to OZEV for 3 years, starting on the date the chargepoint became operational.

What will happen if you do not supply data

OZEV must receive data in full on the relevant due dates. If the data is incomplete, OZEV is unable to identify trends, develop insights and evaluate policy.

Therefore, as a chargepoint operator, you must arrange for the data to be submitted in the required format automatically, without requiring a person to access and draw down the data; this will ensure the data is reliably received without prompting.

Should your data be incomplete or fail to be submitted as per the schedule above, OZEV reserves the right to a repayment of grant funding from the grant recipient.

Servicing and maintenance

You must supply charging equipment with an on-site 3-year warranty on parts and installation.

All chargepoints must have a minimum operational life of 3 years.
