Energy supply

Analyse your requirements – secure a reliable connection to the power network.

The eActros and eEconic can only be put to work if they have the correct infrastructure – and the right preparation. Here a needs analysis is paramount: How many vehicles require charging stations? How energy-intensive are the tours and when can the batteries be recharged? What charging capacities are required? Questions such as these are answered for each customer individually within the framework of our comprehensive eConsulting offering. They are the basis for a charging concept that is tailored precisely to the requirements of each particular company.

Once the charging concept has been developed, the next step follows: determining when and what power peaks occur. What is the maximum electrical capacity used by consumers at present? Typically lighting, IT hardware, air conditioning and production facilities must be taken into account. The energy consumed by the charging stations increases the electrical capacity required overall – particularly when many vehicles are to be recharged at once.

The decisive question is whether the existing connection to the local distribution network is powerful enough to cope with the expected power peaks when you take the charging process into account.

Content depot electrification

If that is not the case, then the local network operator – not the company providing the electricity – must be contacted. The network operator maintains the technical systems which provide the medium voltage (1,000–50,000 volts) from the distribution network to the depot as low voltage (230/400 volts). The network operator is the correct contact whenever changes to the connection capacity are required.

Furthermore, with an intelligent charge management system it is possible to optimise use of the available connection capacity. It can be used to easily start and monitor charging processes remotely. A clearly arranged view provides information about the state of charge (SoC) of each vehicle at any time.

Charge management also offers the option of limiting the usable capacity of the charging stations and of creating a charging profile that is as constant as possible based on shift schedules. Planning of your charge management system is also included in the Mercedes‑Benz eConsulting offering.

Peak shaving is another option for controlling costs. The aim here is to prevent load peaks when consuming energy, thus avoiding excess capacity charges from the energy provider. These can be incurred as soon as the actual current consumption is in excess of the agreed upper limit. Peak shaving prevents that by reducing charging capacity either by way of manual input or by temporarily interrupting the charging process.

The electrification of a depot requires considerable preparation. Following the initial contact, between six and twelve months are usually required to prepare everything necessary to operating the new vehicles.

If a large part of the fleet is to be electrified immediately, it may be necessary to extend the network on-site. In that case you will need to plan for a longer preparation period: the application for expansion and the offer as well as approvals and construction with the assistance of the network operator usually take up to 24 months depending on the network level and location.

That is why it can be helpful to contact the local network operator in good time so that the long-term electrification strategy can be taken into account during expansion of the network. Our Mercedes-Benz eConsulting team also offers extensive assistance on this subject.
