DC (Dynamic charging)

Due to their electric drive systems, trolley buses are an ideal means of transport for busy urban areas. Trolley buses are efficient, quiet, comfortable, exhaust-free and economical to operate. On short routes with many stops, our quiet, smooth-running, low-floor trolleys are equally popular among drivers and passengers alike. HESS trolley technology also handles unusual topographies and climatic conditions with no problems.

The batteries on the roof are charged on average at every fourth stop, while the passengers get on and off. This charging process takes only about 20 seconds.

OPP (Opportunity charging)

At the final stop the batteries on the roof are automatically recharged for a few minutes with renewable energy. This reduces environmental impact and increases the comfort of passengers and residents.

The batteries are charged overnight or during breaks in operation at the bus depot. Recharging both in the depot and at the final stops or at stops with longer waiting times (opportunity charging) has the advantage that a significantly greater range can be achieved without significant restrictions in the operational process. In many cases, it is even possible to completely replicate the operating procedure as it is carried out with diesel buses without an additional vehicle and personnel expenditure.
