Plug-in hybrid by Mercedes-Benz – The technology kit for future consumption targets
Mercedes-Benz introduced the first plug-in hybrid electric vehicles in 2014, starting with the S 500 e an externally rechargeable hybrid with 33 km electric range. Hereinafter, additional varieties with 4-cylinder and 6-cylinder gasoline engines were released out of a modularly technology kit, scaling the internal combustion engine and the electric powertrain in line with the vehicle segment. This way electric ranges of at least 30 km were realized both in the SUV and premium segment. This paper covers the essential characteristics of the modularly technology kit and the different plug-in hybrid powertrains as well as the electric range requirements of the different vehicles. It further illustrates the operating strategy of the Mercedes-Benz plug-in hybrid vehicles and its application. In doing so, the rule-based operating strategy is described based on the main aspects of a fuel-optimal hybrid operation.
