Electric vehicle charging in retail and supermarket: what the SRI measures
Charging is about three things: how many parking spaces have a charging point, whether charging is managed smartly on grid capacity and price, and whether users get information on availability and consumption.
In short
- 1This page shows how the Smart Readiness Indicator (SRI) assesses the electric vehicle charging domain for shops and supermarkets.
- 2For this building type, the domain counts with a weighting factor of 2 out of 3, based on three services: charging capacity, grid balancing, and information provision.
- 3Shops with large car parks and charging points can achieve a notably higher or lower score here, depending on how intelligently charging is set up.
Weight of this domain for this building type
Which services count
| Service | Lowest level | Highest level | Advice |
|---|---|---|---|
| EV Charging Capacity EV-15 · A · 5 levels | Not present | > 50% of parking spaces has recharging point | level 2 or higher |
| EV Charging Grid balancing EV-16 · A · 3 levels | Not present (uncontrolled charging) | 2-way controlled charging (e.g. including desired departure time and grid signals for optimization) | level 2 or higher |
| EV charging information and connectivity EV-17 · A · 3 levels | No information available | Reporting information on EV charging status to occupant AND automatic identification and authorization of the driver to the charging station (ISO 15118 compliant) | level 2 or higher |
Worked example
If everything in this domain is at level 0, the domain contributes nothing. At the highest level for all services, the indicative total score for this building type rises by about 4 percentage points (from 32 to 36 percent, with all other domains at level 1).
Why does electric vehicle charging count for shops?
Many shops and supermarkets have car parks for customers and staff. If charging points are installed there, the Smart Readiness Indicator (SRI) assesses how intelligently that charging is organized. For this building type, the domain carries a weighting factor of 2 out of 3, indicating moderate importance within the total score.
The domain consists of three smart-ready services. Each service has functionality levels from 0 to 4, where a higher level represents greater control and information provision.
Which services are assessed?
The first service, EV-15, examines charging capacity. This concerns the percentage of parking spaces with a charging point: from no facilities to more than half of spaces equipped with a charging point.
The second service, EV-16, assesses grid balancing: whether charging occurs uncontrolled, is one-way controlled based on grid signals, or can even work two-way. With two-way charging, a vehicle can also return power to the building or grid.
The third service, EV-17, addresses information and connectivity. This ranges from no user information to automatic driver identification at the charging point, according to the international standard ISO 15118.
What does this mean for a shop's score?
Shops with fixed opening hours can plan charging profiles relatively easily, because visitor patterns are predictable. This makes controlled charging practically feasible, especially for supermarkets with a large and busy car park.
A shop without any charging facilities scores the lowest level on all three services. A shop with extensive charging capacity, grid balancing, and user information can achieve a high level in this domain, which benefits the building's overall SRI score.
What this means for you
- Owner
- An owner of a shop or supermarket with a car park should inventory how many parking spaces have a charging point and whether charging is controlled. This domain weighs relatively heavily for this building type in the Smart Readiness Indicator, so investments in intelligent charging have visible impact on the score.
- Tenant
- A tenant or user of the property, such as a retail chain, mainly notices whether charging points are available and whether clear information is provided about charging status and waiting time. At a higher level, charging can also be recognized automatically without a separate card or app.
- Advisor
- An advisor assessing the SRI score of a shop or supermarket should verify whether the car park belongs to the building and how many spaces actually have a charging point. Also note whether the charging system is one-way or two-way controlled, as this determines the level for the grid balancing service.
