Introduction
Electric Bikes
Police and
Law
enforcement
Displacements
for
short distances
Touristic
tours
to
different
areas
3
The autonomy and long time of charging
Advantages and limits of an electric bike
4
V2X communication
The results obtained demonstrate that the use of V2X
communications in the context of electric bicycles may
lead to significant energy savings.
5
To achieve such control and traffic management, an
adequate controller is required
500W 1500W
6
Proposed CAN bus-based architecture
CAN Bus
I2C Bus
NO CAN
Bus
ECU 1 Wheel drive
ECU 2 Batteries
ECU 3 Solar panels
Arduino card
Master I2C arduino
Master I2C CAN-I2C

Displayed parameters
Energy given to the motor
Battery temperature
Left range
The driven and cumulated
mileage
Time and date
Battery state of charge (SOC)
Light management
Energy given to the batteries
from solar panels 8
Proposed CAN bus-based architecture
Instantaneous speed
Battery Module
Measures the batteries temperature, voltages and the current to
estimate the battery SOC.

In-wheel drive Control Module
Electric motor and transmission Chain in-wheel motor
- It requires less maintenance (no brushes)
- Higher efficiency
- Higher Weight / Power ratio
- Higher torque / current ratio
- Less clutter ...
11
The Stator: (Fixed part of the motor) consisting of three phases each comprising a number of winding turns
The Rotor: (Rotating part of the motor) consists of a number of permanent magnets alternating between south and NORD.
Hall effect sensors: Placed on the foxed part of the motor (the stator) and delivers a combination of signals as an image of the rotor position
