SERVICES

Turnkey EV charging stations and systems

We can provide all you need for EV charging from chargers to stations and complete systems.
We can provide all products and services required to procure, install, maintain, and service
EV charging equipment from a single point of contact. All our products have been tested in
Finland’s demanding conditions, and our trained specialists possess extensive experience of
charging systems, network connections, installation, and complete project implementations.

Surveys

Looking for the best EV charging station or system for your needs? Considering the
electrification of your heavy-duty fleet? Or perhaps you have already purchased your first fully electric vehicle?

A professional survey of your needs, facilities, and electricity connections is a good way to
clarify the opportunities and limitations of your current places of business.

Our survey is a paid service where we or our authorised experts systematically review your
current needs and near-term plans for electrifying your fleet. We analyse your current
electricity connection, total electricity consumption, and possible upgrades, including costs,
for your location. We provide you with a final report of the survey that presents all the
information in a clear and understandable manner.

Your fee will be refunded with your purchase of charging equipment.

Charging system design

We specialise in the electrification of heavy-duty fleets and versatile EV charging devices and systems. Our solid experience comes from having delivered over 30 MW of charging power
and 500 charging points.

You can rely on our experts to design the perfect charging solution for your needs. Our design
service includes determining the charging power requirements, choosing the right
equipment, specifying the electricity connections, and a preliminary implementation and
project plan.

Electricity connections

Heavy-duty vehicles require plenty of power to charge, meaning high-power chargers.

In practice, charging power at most bus depots starts at 350 kW. Future plans and
expandability should be considered from the purchase of the first fully electric trucks and buses.

There are two main types of electricity connections, and most properties have conventional
400 V three-phase power, which is a low voltage connection. Depending on the distribution
network operator, the connection’s capacity ranges from 3 × 630 A to 3 × 1,000 A. These
connections can provide a maximum output of 720 kW.

Larger sites always require a medium voltage connection. Medium voltage connections must
have a local transformer substation installed on the property or nearby, connected to the 10
kV or 20 kV distribution network. The distribution network operator may provide only the
connection or allow the customer to purchase the substation as well. With growing needs, a
rented substation may prove to be the optimal solution in terms of cost and performance.

Technical building services

Other electrical systems at the property, such as a depot, should be reviewed when
electrifying heavy-duty fleets.

There are several regulations and obligations for the proprietor regarding the technical
building services of properties, industry, and different production facilities. We can handle all
of these for you to achieve full compliance.

For example, common issues include operational control of electrical equipment (always
required for medium voltage connections), standby set and uninterruptible power supply
maintenance, emergency lighting centres, and compensating equipment. Energy efficiency
has also become very important with the volatility of the price of electricity.

Consultation

Our strong experience in the electrification of urban transport combined with our electrical
engineering professionals and our group’s role as an electric bus importer, dealer, and
charging solution provider makes us a unique operator on the Finnish market.

We also wish to share our expertise with companies who are only now considering or
preparing the electrification of their fleet. Our experts can help you define your charging
needs: when and where your fleet needs power, how chargers should be positioned, what
charging options there are for the available vehicles, and all matters concerning charging
infrastructure and electricity connections.

Contact us so we can work out a suitable introduction programme or project plan for your
business.

Financing

The electrification of heavy-duty fleets requires considerable investments in both the vehicles
and their charging systems.

Transport operators are of course familiar with purchasing vehicles and estimating their
running costs. What is often unclear with EVs are the new types of costs associated with
chargers, electricity infrastructure, and especially the electricity connection.

YES-EU is ready to help with your new vehicles all the way from purchasing, and we offer low-
cost financing solutions for our full selection of chargers, charging systems, and electricity
infrastructure services. For smaller devices, we offer pre-approved hire purchase agreements
from our partner Proventum Oy. For larger projects, we can negotiate suitable leasing arrangements.

BATTERY STORAGE SYSTEMS

RESS battery storage

RESS Battery Storage for Detached Houses, Semi-Detached Homes, and Cottages

Store Solar Power–Use Energy When You Need It. Our RESS battery storage solution is
specifically designed for energy storage in small residential buildings (such as detached and semi-detached houses) and holiday homes.

Increase Self-Sufficiency with Solar Energy and Energy Storage

Solar panels have rapidly become more common, and more and more property owners are producing their own renewable energy using solar panels. The full benefit of solar power is realized when the energy can be stored and used by your property’s electrical devices when it’s needed the most–in the evening, at night, or even during a power outage.

With a 2 kWh–28 kWh battery storage system, you can boost your energy self-sufficiency, lower your electricity bills, optimize the use of solar energy, and reduce dependence on the power grid.

ESS energy storage

Scalable ESS System for Renewable Energy Utilization and Storage

The ESS (Energy Storage System) cabinet is an intelligent and scalable battery storage system that enables the efficient storage and use of renewable energy—such as wind or solar
power—especially when production does not match consumption.

Its modular design allows the system to be customized for various application sizes. ESS components can be connected in parallel to create large-scale energy storage units that meet specific operational requirements.

ESS System – For Demanding Energy Storage Needs

The ESS system is designed for demanding energy storage needs in industry, buildings, electric bus and heavy-duty vehicle charging infrastructure, and as support for the power grid. It balances production and consumption, reduces dependency on the grid, and lowers energy costs.
