In reality, the battery electric heavy trucks of today have insufficient range for many applications. Even the mighty Tesla Semi (once it actually becomes widely available) will have its limitations. No matter how aerodynamic the shape of the cab or how large the battery, hauling a fully loaded semi-trailer uphill to the Eisenhower Tunnel in the Rocky Mountains will always be a challenge for battery-powered tractors. Mahle, a tier-one supplier to the automotive and trucking industry, claims to have a solution.

In a press release, the company said trucking companies face the dual challenge of reducing emissions from their operations without jeopardizing their economic viability or competitiveness. Inadequate charging infrastructure for commercial vehicles in many regions and the limited ranges of battery electric trucks are the two leading reasons why electrification of heavy-duty trucks is lagging. Flexibility and reliability are the key factors for business success in this sector.
