This paper brings the theoretical approach to the sizing of electric drive for the special light vehicle — mountain bike, optimal design and concept of the power chain, specifics of components and some results from practical tests in the field. The prototype power and characteristics are sufficient even in the heavy terrain for all supposed aims. Some results from the prototype practical tests are...
This paper brings the simplest equivalent circuit of electrochemical battery suitable for the modeling of its state of charge SOC in electrical vehicles, with varying load where the characteristics for constant current cannot be easily exploited and also the recuperation is is solved. The proposed circuit has one variable current source representing two processes, the self-discharge and the capacity...
The energy conversion, which includes the energy storage in the electrochemical battery is not very effective, therefore the recharging of battery from the engine at longer trips is not suitable. The proposed concept of plug in hybrid (PHEV) offers instead of a generator the standard manual gearbox connected with one axis and the second axis of vehicle is driven by electric motor EM. The comeback...
The super-capacitor SC, due its low internal resistance, can reduce the SLI battery size, prolong its lifetime and improve the starting ability of internal combustion engine ICE namely at low temperature or at worn-out battery. To verify the SC suitability the DYNAST model has been prepared, where various influences can be examined. The actual model includes important resistances and inertias as well...
