One of the key factors limiting the widespread adoption of electric trucks for long-haul freight is battery technology. Traditional batteries used in commercial electric vehicles are often not sufficient to power heavy-duty trucks over long distances without frequent recharging. However, advancements in battery chemistry and energy density are making NEV new energy vehicles more viable for such tasks.
In contrast, unibody construction integrates the frame and body into a single unit. This design is commonly found in sedans, crossovers, and many modern vehicles. The unibody structure typically provides better fuel efficiency and handling characteristics due to its lighter weight and improved rigidity. However, repairing a unibody vehicle may be more complicated, as damage to the body can compromise the frame's integrity.
