E-Mobility
Planning e-mobility
E-mobility is a major consumer within a property or site. With the increasing number of available charging stations, the following points must be clarified for every planned infrastructure:
Load management for e-mobility
Load management, or the behaviour of the charging stations with defined resources, is directly related to the effective availability of the charging stations and the reliability of the entire installation.
In general, as soon as there are two or more charging stations in the system, a load management must actively control the capacity distribution.
This is intended to prevent excessive power consumption by the charging infrastructure from tripping the fuses that protect the infrastructure. The result would be a temporary power outage in parts of or across the entire site, as well as service work to restore the situation.
At the same time, a reduction of the charging power must be ensured when the energy supplier has to protect its grid in the event of undersupply.
In addition to overload protection, load management usually takes on further functions:
-
Overload protection of the installation
-
Optimisation of the energy distribution among active charging sessions within the site
-
Consideration of other consumers in the system and prioritisation of these consumers over the charging infrastructure
-
Prioritisation of the charging groups among each other
-
Prioritisation of the tariff used to charge the vehicles (e.g. grid-power or solar-optimised)
You can find more details under "Load management description" in the respective topic section.
Billing e-mobility to tenants
Charging stations are large consumers and generate corresponding costs when used. Primarily the energy used for charging, but also the operating power and the resulting losses, as well as any rental of the charging station.
Billing can be based on a single tariff or multiple tariffs, e.g. peak, off-peak and solar tariff, depending on the hardware used and the combination of billing solutions.
You can find more details under "Billing" in the respective topic section.
Billing e-mobility to third parties or unknown users (public / semi-public)
Installing charging infrastructure often involves high costs. A good way to accelerate amortisation, or to enable a desired public offering, is to make the charging station accessible to third parties.
To make a charging station available to the public, e-mobility backend software is required.
The backend software then handles the release of a charging session to third parties, depending on your needs and the chosen payment method.
