Electric car charging in motion
Electric car uses a wind turbine to charge the batteries in motion to increase the traveled distance.
Figure 2. Dependence between the increases of electro car run and drag coefficient of wind turbine. Charge of car battery by wind turbine is carried out at the time of car movement. Wind=5m/s (counter wind)
Figure 3. Dependence between the increases of electro car run and drag coefficient of wind turbine. Charge of car battery by wind turbine is carried out at the time of car movement. Wind=0. CP-wind turbine power coefficient (corresponds to the “beta” at figure 2.)
Figure 4.
Dependence between the increases of electro car run and power coefficient of wind turbine. Charge of car battery by wind turbine is carried out at the time of car movement. Blades of wind turbine are arc profile. The size of the blade has 0.625m to 0.5m.
Calculation of the increase in distance running because electric charging by wind turbines is carried out using the following procedure:
1. Calculated power of the wind turbine on the vehicle speed of 90 km / h
2. Calculate power requirements to overcome the additional aerodynamic drag of the wind turbine
3. Determines the power that can be used to increase the energy accumulators
4. Using a predetermined amount of energy consumption of electric vehicles on the 100km path defines additional distance which is obtained when charging is in motion.
