Conventional Lithium –ion battery packs of 1 to 3 KWhr are connected in parallel and series of cells to achieve 48 V required for e-scooter and e-rickshaws. This limits the number of cells to be used and leads to costly Battery management system. A few weak cells reduce the performance of the full battery pack. Participants to develop a new concept of which will integrate boost convertor from 3.7 V to 48 V rated voltage and also integrate motor controller function.
This requires advance BMS development for locking and unlocking the Lithium ion battery BMS on basis of monthly payment by customer. The battery operating vital parameters to be stored in cloud for later retrieval during maintenance. Participant to develop logic and the embedded system for battery capacity from 1 to 3 KWhr purchase on lease instead of one time investment in lithium battery. This will promote E-mobility solutions over conventional fuel scooters.
BLDC motor know for high power density design and high efficiency. As the speed of the vehicle increases the motor becomes inefficient due to increase in losses. Scooter motor is in range of 500 to 3000W for 25 to 60 kmph speed application. Participant to derive at most efficient combination of motor sizes, hub motor versus transmission driven off hub motors for improved torque-speed characteristics, arrive at controller design for cater low and high vehicle speeds. This involves motor design s
