Battery Payload Loss: Why Electric HGVs Are Uneconomic at 44 Tonnes
For 44-tonne operations — where the two-tonne battery derogation does not apply — the economics of electric HGVs are materially worse than diesel. The problem is not energy costs alone: operators must run more vehicles and more miles to move the same tonnage.
