PERFORMANCE
Objective to get:
TOP SPEED & GRADEABILITY
According to your wants & needs
By determining:
Electric motor technical specifications:
Power, Torque, Consumption & RPM
Prevent vehicles from :
SLIP, SKID, AND ROLL
VEHICLE STABILITY
By determining:
Load distribution
Noted:
Another focus in the design is the selection of the type, size and capacity of the battery and other vehicle components
CONVERSION STRATEGY DETAILS
SAFETY FACTORS
Prevent vehicles from:
Electrical shock & Overheat
By determining
Warning & Security System
2. DEVELOPMENT BASED ON CONVERSION FROM ICEVs
θGradeability: - Calculation of traction force & drag- Resistance force : 𝐹𝑟 = 𝐹𝑎𝑒𝑟𝑜 + 𝐹𝑟𝑜𝑙𝑙 + 𝐹𝑐𝑙𝑖𝑚𝑏
PERFORMANCE – Gradeability
1. Load distribution design2. Center of Gravity calculation3. Stability Calculation
Stability analysis in turning vehicle dynamics:• Avoid Slip• Avoid Skid• Avoid Roll
VEHICLE STABILITY
1. Protection from electrical contact: direct & indirect2. Battery Evaluation: Battery specifications, Markers, & cable installation3. Operating safety:
• Warning system when going to drive,• When leaving the vehicle • When charging the battery
4. Hydrogen emissions: threshold mainly for lid acid batteries5. Car sound: give awareness to surroundings by adding a sound-producing
device to the EV car
SAFETY FACTORS FOR BEVs
BASED ON ICEVs
ICE Vehicles
Conversion Strategy
Conversion ICEVs to BEVs Strategy
• Performance • Top speed• Gradeability• Power & Torque• Speed• Fuel consumption
• IoT-based on IVC facility • Performance• Maintanance• Service
