MAN Trucks tests hybrid TGL truck with Customers
Posted On: Friday 5 August 2011
MAN Trucks are currently putting its new hybrid truck to the test in Munich. Two MAN TGL 12.220 Hybrid distribution trucks are being tested to provide information that MAN can use to improve its hybrid truck. The loads to which individual hybrid components are subjected and the stability of the system are just two examples of the information that the data provides.
The MAN TGL 12.220 Hybrid has a four-cylinder common-rail diesel EEV engine with an output of 220 hp plus a 60 kW electric motor. MAN expects that trucks in distribution transport will use up to 15 percent less fuel.
Besides the combustion engine, electric motor, and automated six-speed transmission, the hybrid-drive system as a whole also consists of a compact lithium-ion battery as the high-voltage source and additional power electronics for controlling the electric motor and supplying the 24-V on-board network from the high-voltage system. It performs all the functions of a full-hybrid system: stop/start, recuperation of braking energy, support when accelerating (boosting), and electrically-powered driving. The intelligence of the system is seated in MAN's hybrid energy management, controlling the energy flow between diesel engine, electric motor, energy storage, driving axle and auxiliary units. Here, energy management optimizes the torque split between the diesel engine and the electric motor. Alongside that, power on demand is ensured for operation of the auxiliary units.
