Reliability is an important vehicle performance. It mainly depends on the fatigue life of the key auto parts. As the key component in transmission system of the truck, gearbox's efficiency and reliability are closely linked with the truck's power and safety. In the paper, by using multi-body dynamics and finite element method, the fatigue life of the(More)
This paper presents an optimized energy management strategy for Li-ion power batteries used on electric vehicles (EVs) at low temperatures. In low-temperature environments, EVs suffer a sharp driving range loss resulting from the energy and power capability reduction of the battery. Simultaneously, because of Li plating, battery degradation becomes an(More)
On the basis of parameters matching for powertrain of an electric bus and its key components experiment verification, powertrain control system was focused designed and studied. The control strategy of driving torque and motor overload protection were developed, the method of battery power management was confirmed, in accordance with vehicle brake system, a(More)
