Shanghai Jiao Tong: understanding an electric vehicle beyond its battery
Chinese programs / Industry and mobility / English edition
What you will learn to do
Link the battery, propulsion, and controls to the evaluation questions of a mobility project.
Documented reference: electrification training published by Shanghai Jiao Tong for BorgWarner, fact sheet updated in 2024. The course and the VOCE case are original.
The course
The training published by Shanghai Jiao Tong addresses the functions of the battery, motor, and controls of an electric vehicle. Its curriculum also includes vehicle thermal management. This scope requires examining a complete system.
In a fictional delivery company, a buyer compares two vehicles. He selects the one whose battery stores more energy, assuming it will necessarily be better suited for all routes.
Storage capacity is useful, but it does not describe the entire task. One must also examine traffic conditions, the load carried, and recharging possibilities. A route with frequent stops does not stress the vehicle in the same way as a continuous journey.
In a fully electric vehicle, the traction battery provides energy to the propulsion. The power electronics controller manages the flow to the motor. Components must operate under suitable thermal conditions. The project therefore depends on how these functions are integrated.
The buyer does not need to become an electrical engineer to ask the right questions. He must ask about the conditions of the announced measurements and a test corresponding to his routes. A published range without a description of the context is not enough to establish the result for his company.
This reading also prepares a training program. Drivers, operations teams, and technicians do not require the same instruction. Daily driving, charging organization, and technical interventions correspond to different responsibilities.
Your decision
Two vehicles complete an identical fictional route. The first finishes with more remaining energy but requires a longer recharge before the next route. What information is missing to make a choice, and who should participate in the decision?
Formulate an answer before opening the answer key.
Open the reasoned answer key
One must know the schedule of the next route, the duration and conditions of recharging, equipment availability, and the need for service continuity. Remaining energy alone does not determine operational availability.
Associate fleet and operations managers with those in charge of the charging infrastructure. Have technical constraints verified by competent professionals. Then, define the criteria for testing on real routes, without concluding that one of the vehicles has universal superiority.
Production to keep
A comparison grid based on routes, availability, and recharging conditions.
Evaluation criterion
The participant examines the service to be performed and its constraints, instead of choosing based on a single battery figure.
