Hybrid Perspectives

Battery Technology

For many years, storage of electricity was a major handicap for hybrid vehicles. However, vehicle engineers and battery developers have now made the breakthrough: modern lithium ion batteries combine high power density with a large storage capacity. In addition, they can deal with frequent and rapid charge and discharge cycles.

Long-Distance Transportation

The frequent alternation between acceleration and braking, as well as the particularly emission-sensitive environment, mean that hybrid drive systems are predestined for local transportation. However, depending on topography, they can also achieve notable consumption benefits in long-distance transportation: by an average of four percent, according to calculations by Daimler Trucks. Due to the high numbers of kilometers driven and the corresponding large amount of fuel required, the sum of achievable benefits is even higher than in distribution vehicles in local transportation. On the other hand, they entail a payload reduction due to additional hybrid engines. Daimler Trucks and Daimler Buses are planning tests of hybrid trucks and touring buses with hybrid drive systems in everyday use for long-distance transportation applications.

Emission measurements

Despite a wealth of recent success, hybrid vehicles still face unresolved challenges. For example, classification according to emission standards and the measurement cycle for determination of emissions have yet to be clarified. Rapid agreements and provisions are vital to provide manufacturers and operators of hybrid vehicles with security. For example, a standardized measurement cycle for hybrid vehicles is taking shape in Japan.
