Sample questions
01What is the maximum DC voltage typically used in current rapid charging systems?
- A.800V
- B.1000V
- C.1200V
- D.400V
Why: Modern rapid and ultra-rapid DC chargers commonly operate at up to 1000V DC to deliver high power, with 400V and 800V being typical vehicle battery architectures.
02Which type of connector is standard for Type 2 AC charging in the UK?
- A.CHAdeMO
- B.Tesla Supercharger
- C.CCS
- D.Mennekes
Why: The Mennekes (Type 2) connector is the European and UK standard for AC charging, defined in the BS EN 62196 series.
03What is the minimum copper cable cross-sectional area typically used for a 32A EV charging point on a domestic radial circuit?
- A.4mm²
- B.6mm²
- C.2.5mm²
- D.10mm²
Why: 6mm² copper is typically selected for a 32A EV charge point so the current-carrying capacity and voltage drop requirements of BS 7671 are met for the installation method and route length.
