Abstract [eng] |
The aim of this thesis is to research the braking process of hybrid car and to measure the amount of regenerated energy when braking intensity is uneven. In the theory of this thesis discusses the types of hybrid cars, based on level of technology used to make them. Particulary are analyzed those components of the hybryd car which are used to produce the regenerated energy. In the part about research methods describes the measuring equipment used for experiment and alsot the conditions of experiment. The influence of the wind speed is estimated from the roll on free gear it was made equal to 1 m/s. During these experiements the primary wheel resistance coefficient value which is 0,008195 and also methodology part describes the result getting ways. Finally in the result part shows the values which are counted during the experiments with kinetic energy alteration – ΔEk, used for aerodynamic – Eaer, ride resistance – Er force, frictional braking – Estab and the reganerated to batery power thrust amount – Eįbat. Conclusions shows that the biggest regenerated amount of energy value is equal to 0,11468 kWh when braking in the average 0,78409 m/s2 acceleration. When braking in this specific acceleration from given amount of kinetic energy 67,66 % regenerates into thrust batery and the other amount of the energy is used to overcome the force of resistance and to brake using frictional brakes. |
