e-troFit: Retrofitting instead of buying new ones - this is how diesel buses will drive electrically in the future
From a combustion engine to an electric vehicle: diesel buses can now have an environmentally friendly “second life” as an electric bus. Under the name e-troFit, the BDStar's subsidiary and the Munich-based development specialist in-tech presents a solution for professional conversion to electric drives. As a system supplier, ZF Aftermarket contributes the necessary drive components and at the same time offers access to their worldwide workshop network. in-tech presents the e-troFit concept to the public at the eMove360° trade show.
Emissions in city centers – diesel buses must get out of the city
The debate on diesel bans poses new challenges for many local authorities: What happens to diesel buses in local public transport? “High emission levels in city centers are forcing local authorities to take action,” says Andreas Hager, head of the New Mobility Solutions business unit at in-tech: “Many operators are therefore looking to get started with electric mobility. However, replacing existing bus fleets completely with new electric vehicles is neither economical nor sustainable – a new electric bus is considerably more expensive than a conventional diesel bus.
Smart, affordable, sustainable: up to 50% cost savings compared to new purchases
Retrofitting is the smart and sustainable alternative to buying a new vehicle. The retrofit solution is up to 50% cheaper than a new vehicle. “In addition to the lower acquisition costs, e-troFit also has other positive aspects, as the service life of existing vehicles is extended. Wear-prone drive components will be replaced as part of the conversion, and thanks to the refurbishment and modernization of the passenger compartment, a sustainable second-use of the vehicle as an electric bus will be possible,” explains Andreas Hager.
Strategic Partnership with ZF – Conversion with Series Quality
in-tech has signed a preferred partnership with ZF Friedrichshafen AG for the market launch of e-troFit. Helmut Ernst, Head of ZF’s Aftermarket Division, comments: “Together with in-tech, we are offering a one-stop shop solution for the retrofit: With AxTrax AVE and CeTrax, ZF not only supplies the right products for this. In addition, we provide the required expertise including workshop capacities and act as a trading and service partner for in-tech and our customers”.
ZF supplies original components – the AxTrax AVE electric portal axle and the CeTrax electric central drive – and offers access to the worldwide workshop network. AxTrax AVE is ideally suited for the fully electronic drive of city buses of all manufacturers. CeTrax can be installed directly into the existing vehicle platform without having to make major changes to the chassis, suspension or differential. Compared to other solutions, ZF’s central drive offers significant weight advantages, high performance, and excellent efficiency. In combination with in-tech’s extensive development competence, the partnership ensures that a high-quality product comparable to a serial production vehicle is created.
