Heavy truck battery energy storage

Are heavy battery electric trucks infeasible?

Research on the decarbonization of transport often concludes that heavy battery electric trucks are infeasible due to the incompatibility of long driving distance with high energy use and low specific energy and high costs of batteries.

Do battery electric trucks save energy?

We model battery electric trucks that use high-power fast charging, enabling smaller batteries and showing that the economics of battery electric trucks per ton-kilometer improves with greater weight, driven by increasing load capacity as well as increased energy savings as a function of weight.

Are battery-electric trucks the future of freight transport?

The costs of battery and fuel cell systems for zero-emission trucks are primed to decline much faster than expected, boosting prospects for their fast global diffusion and electrification of freight transport, with battery-electric trucks probably leading.

How much does a truck battery degrade at the end of life?

In addition to this, a margin for battery degradation is included, assuming that usable capacity can on average (over the life time of the truck) only be 85% of the capacity available for charging. This allows batteries to degrade 30% at end of life, with an average capacity loss of 15% midpoint in life.

Why do we need a heavy-duty diesel truck?

Increasing manufacturing activity increases road freight. Transportation with heavy-duty diesel trucks (DTs) emits 1.8 Gt CO 2 yearly and must achieve a 6% annual reduction for carbon neutrality. 1 Electrifying heavy-duty trucks is urgent but lags significantly behind passenger cars.

Are heavy trucks harder to electrify than lighter trucks?

We also argue that previous findings pointing out that heavy trucks are harder to electrify than lighter trucks are very sensitive to assumptions about the battery cost and battery lifetime. Because battery technology is improving fast, the feasibility of heavy battery electric trucks is also changing fast.
