Germany truck manufacturers and government therefore are planning for ~ 75% of new
truck sales in 2030 to be zero emission
Page 2
Those sales figures will
only be met if sufficient
infrastructure to power
those trucks can be put
in place.

Zero emission trucking, especially the direct electric kind, can be cheaper than
diesel by 2030, with infrastructure costs playing only a minor role

But there are some challenges for battery electric long-haul trucks and
stationary charging
Page 4
Examples of questions raised regarding BEVs and stationary charging
1) Can reliable supply chains for big batteries be established?
2) Can the grid cope when lots of trucks charge?
3) Is there space for all those charging stations?
4) How to ensure high availability of charging equipment?
5) How will booking be done and cope with traffic situations?
6) Can everything scale up fast enough?
Adding dynamic charging to the technology mix helps alleviate all these concerns
So let‘s dig deeper into what dynamic charging is →

BEVs can reach their full economic and ecological potential
when using a combination of dynamic and stationary charging
• Increases battery use and
energy losses
• Loss of time, unless used
during planned stops
• Very high local grid load
• Additional space demand
• Higher threshold of min.
number of users
• Dependent on road
operator’s cooperation
• Higher technical complexity
A combination of dynamic charging & stationary for BEVs makes sense because they
• Offer the most mature technologies for decarbonization
• Are the most energy-efficient solutions, which saves costs and emissions
• Complement each other’s use cases strongly, with high power chargers enabling broad geographical coverage quickly
and dynamic charging easing the scaling up on the core corridors

weaknesses
• Many vehicles can be
charged at the same time
• Hardly any additional
land required
• Established technology with
manageable adaptations for
road
• Easier load on the grid
• Simple stand-alone
solutions
• Gradual build-up with large
spacing and few points per
location possible

Cost of Ownership (TCO)
Reduces the size of batteries
and cost of zero emission trucks
Reaching customers reliably,
without stopping or waiting
Cheap renewable energy still
limited in availability
Avoids supply chain bottle necks,
esp. for critical raw materials
Staying within GHG budget for
1.5 °C warming
Spreading loads over time and
space helps the grid
Upgrade of existing road infra-
structure on the busiest corridors
Well-known and proven
technology to roll out quickly
Energy efficiency Resource efficiency In time
