Question 1

At what fleet size do we need a dedicated EV operations team?

Accepted Answer

Around 100 vehicles. Below that, one accountable fleet owner plus contracted high-voltage service is right; a dedicated team at 30 vehicles adds cost without removing risk.

Question 2

How many drivers can one supervisor manage in an EV fleet?

Accepted Answer

Plan for 25–30 per shift — just below the classic first-line ceiling of about 30, because an EV supervisor also allocates charging bays and handles state-of-charge exceptions.

Question 3

Should charging decisions be centralised or left to each depot?

Accepted Answer

Centralise the policy, localise the execution: head office sets the charging window and override rules; the depot decides which vehicle plugs in where.

Question 4

How much operating overhead should we budget to scale EV fleet operations?

Accepted Answer

About six full-time equivalents at 100 vehicles: four shift supervisors, two HV technicians, two half-roles. At 500, supervisors scale linearly to 18–20 but the specialist core only doubles.
