School Bus Electric¤
School Bus Overview¤
The School Bus is engineered to transport 15 or more passengers, serving primarily in the conveyance of students to and from educational institutions.
School Bus Performance Metrics¤
- Annual Distance (dannual): The school bus covers an annual distance of 24,000 km.
- Average Occupancy Rate (nlpv): It boasts an average loading capacity accommodating 47 passengers per vehicle.
- Utilization Window: The vehicle is utilized for 5.26 hours per day, translating to a 22% capacity utilization, according to the study by Duran and Walkowicz1.
- Reference Capacity: The reference capacity, derived from these parameters, is calculated to be 585.31 passenger-kilometers per hour (pkm/h), utilizing the formula:
Where cp represents the capacity utilization percentage. Where the denominator reflects the total hours in a year multiplied by the capacity utilization factor.
Battery Electrical Vehicle¤
A 100% electric vehicle is powered solely by electricity. This electricity is used to supply an inverter with direct current which, using the principle of electromagnetism, converts electricity into mechanical energy and moves the vehicle. As the vehicle is not connected to the electrical grid while on the move, it is necessary to ensure its power supply by other means. To do this, BEVs store electricity in an on-board rechargeable battery.
Among the battery types presented, lithium batteries are the ones found in electric vehicles currently on the market. Lithium batteries offer the ability to store more electricity (i.e., have greater energy density) in a smaller volume than traditional batteries, such as lead-acid and nickel-metal-hydride batteries. Lithium batteries are also lighter than conventional batteries.
