History and Background

Early Innovations in Electric Freight Transport

The concept of electrified freight vehicles can be traced back to the late 19th century, when early experiments with electric trolleys demonstrated the feasibility of battery-powered transport. However, these early systems were limited by battery technology, range, and the lack of a robust distribution network. The rise of heavy industrialization in the early 20th century led to the development of internal combustion engines as the dominant power source for freight vehicles, largely due to their superior energy density and flexibility.

It was not until the late 1990s and early 2000s that the convergence of lithium-ion battery advancements, increased demand for sustainable logistics, and the proliferation of GPS-based route optimization created a conducive environment for electric freight solutions. A handful of pioneering companies began experimenting with electric cargo trucks, primarily in niche markets such as waste collection and short-haul deliveries.

Commercialization of ehaulers

The term ehauler entered the public lexicon around 2012, when a consortium of urban planners, automotive engineers, and environmental scientists formalized a definition for electric haulers that emphasized modularity, battery efficiency, and integration with city-wide logistics networks. In 2014, a joint venture between a European automotive manufacturer and a North American waste-management firm introduced the first commercial ehauler designed explicitly for municipal solid waste collection.

From 2015 onward, a series of pilot programs across major metropolitan areas demonstrated the operational advantages of ehaulers, including lower fuel costs, reduced noise pollution, and improved route predictability. By 2020, more than 4,500 ehaulers were in active service across 15 countries, spanning applications from recyclable material transport to e-commerce parcel delivery.

Key Concepts and Terminology
