Electric vehicle charging in industry and manufacturing: 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 domain Electric Vehicle Charging counts toward the Smart Readiness Indicator for industry and manufacturing.
- 2It covers three services: charging capacity, grid balancing, and user information provision.
- 3For industrial buildings, this domain carries average weight, with a weighting factor of 2 on a scale from 0 to 3.
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 33 to 37 percent, with all other domains at level 1).
Why does electric vehicle charging count for industrial buildings?
The Smart Readiness Indicator (SRI) assesses buildings across nine domains. Electric vehicle charging is one of those domains. For industry and manufacturing, it concerns only the building and its installations, not the production process itself.
Industrial buildings often have large electrical connections. This makes charging flexibility valuable: the business can adjust charging capacity to grid capacity and energy prices. For this building type, a weighting factor of 2 applies on a scale from 0 to 3. The domain therefore counts as average weight in the overall score.
Which smart-ready services belong to this domain?
The SRI methodology assigns three smart-ready services to this domain, each with functionality levels from 0 to 4 or fewer, depending on the service.
- EV-15 Electric vehicle charging capacity: measures what proportion of parking spaces have a charging point, from not present to more than half of the spaces.
- EV-16 Grid balancing during charging: measures whether charging is controlled based on grid signals, in one direction or in two directions, where the vehicle can also return power.
- EV-17 Information and connectivity: measures whether users receive information about charging status and whether the system automatically identifies the driver at the charging point.
For industrial buildings above 290 kW installation capacity, building automation is often already in use. This makes it logical to also control vehicle charging on site intelligently.
What does this mean for an industrial building in practice?
Many industrial sites still have limited charging infrastructure for staff or company vehicles. A charging point without control scores at the lowest level, even if many charging points are present.
Control based on grid capacity is particularly relevant for industrial buildings. A large electrical connection means that charging at peak times can significantly affect the business's overall energy consumption. Bidirectional charging, where vehicles also return power, delivers the highest level for grid balancing.
What this means for you
- Owner
- An industrial building owner should not view charging points in isolation from the energy management that often already exists for the production process. By linking charging control to existing systems for grid capacity and pricing, the owner raises the score on this domain without major additional investment.
- Tenant
- A user or employee mainly notices whether information is available about charging point status, for example whether it is occupied or how much has already been charged. At a higher functionality level, the system automatically recognizes the driver, making charging simpler.
- Advisor
- An advisor must distinguish carefully between charging infrastructure for the building and installations that belong to the production process for industrial buildings, since only the first category falls under the SRI. When assessing, pay particular attention to the presence of controlled charging, because this makes the difference between an average and a high score on this domain for buildings with large electrical connections.
