The image shows the log of an electric semi-truck as it travels through its work day in California, making deliveries. The graphs shows battery charge (percentage) against accumulative miles traveled.

What is most likely happening from around 21.00-midnight (5.)?

Intermodal logistics refers to

A semi-truck has a usable battery capacity of 438 kWh and a relatively flat charge curve. Its maximum charging rate is 270 kW. What is the least amount of time from the list below that it is likely to charge from 0% to 80%.

Which standard of charge point connector does the image describe?

All the following statements are true. Many factors can impact the battery performance, but pick the two that best describe the battery’s life cycle:

When considering the power draw on a circuit, you could use the following formulae:

P(VA) = √3 * V (Volts) * I (Amperes) / PF * EF

What would you most likely be measuring?

Which vehicle-specific parameters would NOT impact an HDEV’s performance?

How is a battery’s state of charge usually measured?

Which of the following formulas would you use to calculate an EV’s efficiency?

In the image shown, a simple DC circuit is shown. What is the theoretical power generated by the batteries in the circuit?
