Three sites, three priorities
| Site type | Main need |
|---|---|
| Company depot | Deliver the required energy before the vehicles' planned departure. |
| Charging during longer parking | Use the parking time and coordinate demand with the building. |
| Public fast-charging hub | Handle irregular arrivals and short-term high simultaneous demand. |
In every case, we also assess the actual charging profile. A vehicle does not draw the charger's rated power throughout the whole process.
Power and energy are two different problems.
A grid connection may allow the required energy to be obtained over a day but not be sufficient during a short peak. A battery can supplement this requirement.
However, if the total amount of energy and the room to recharge the BESS are also lacking, storage alone will not solve the problem in the long term. We therefore look at the whole cycle: charging the battery, charging the vehicles and getting ready again for the next simultaneous demand.
Control prevents unnecessary oversizing.
At a depot, smart charging can distribute power according to departures and the energy required. At a public site, we model the frequency of arrivals and the use of the charging points.
We look at a shared battery for several points and for the site's other consumption. Whether the architecture is suitable depends on the specific project.
Let's design the target state and invest in stages.
The number of vehicles and the use of the site can grow. We compare charging control, a battery, own generation and a grid connection upgrade, including phased implementation.
Where BESS is used as an interim solution, we also evaluate its role after a later grid upgrade.
