7. EV Components Electric motor Inverter Battery Control Module It regulates the power flow from the battery to the motor. It should be capable of handling the maximum voltage and current levels required by the system. Drive train

8. Factors to consider – Motor Sizing V ehicle weight D esired speed R ange impact the performance and efficiency of the vehicle.

9. Influence of Battery on Motor sizing Advancements in battery technology directly influence motor size optimization. Higher energy density batteries enable the use of smaller motors without sacrificing performance This leads to more compact and lightweight electric two-wheelers

10. Tractive Effort - Comparison Electric machines with favorable torque–speed characteristics can satisfy tractive effort with simple single-gear transmission.

11. Influential Parameters on Range 1 ) Direction of wind 2) size of tyre and air inside tire 3) riding position 4) how healthy your battery is 5) Weight of rider 6) Road condition  7) how many times brake & accelerate applied 8) Going on a flyover or uphill

12. Design

13. Influential Parameters of Power Factors desired speed rider weight terrain desired range Power (W) = (Rider Weight + Cycle Weight) × Rolling Resistance × Speed + Air Resistance + Gradient Resistance.

14. Influential Parameters of Power Battery Capacity ( Wh ) = Power (W) × Time (hours ) Charging Time (hours) = Battery Capacity ( Wh ) / Charging Current (W)

15. Calculations - Power Radius of tire = 33cm or 0.33m Centre to Centre distance = 56cm Weight of cycle = 52kg Weight of passenger = 62kg Under no load condition: Motor rpm = 540rpm Rear wheel rpm = 296rpm Circumference = 2r = 2×3.14×0.33 = 2.0727m Speed of bicycle Surface speed = circumference × rpm = 2.0727×296 = 613.4304m/min

16. Calculations - Power Surface speed (km/min) = 613.4304/1000 = 0.6134Km/min Surface speed (km/h) = 0.6134×60 = 36.8Km/h
