EVSE-100

The meter is a part of the Sonel MeasureEffect™ platform. It is a comprehensive system that enables you to take measurements, store and manage data, and provides multi-level control of your instruments.

Applications

The meter makes it possible to carry out diagnostics on:

• AC electric vehicle charging stations with type 2 connector with socket or fixed charging cable (1-phase and 3-phase),
• portable electric vehicle charging stations with type 2 connector (1-phase and 3-phase),
• charging cables.

Basic functions of the device

• Simulation of PP cable parameters:
  • open circuit,
  • 13 A, 20 A, 32 A, 63 A, 80 A.
• Simulation of CP communication:
  • state A – vehicle not connected,
  • state B – vehicle connected, not charging,
  • state C – vehicle connected, charging without ventilation.
  • state D – vehicle connected, charging with ventilation.
• Safety measurements:
  • measurement of short circuit loop Z,
  • measurement of parameters of RCD circuit breakers (AC, A, B, 6 mA DC),
  • measurement of insulation resistance R_ISO,
  • measurement of R_CONT,
  • phase sequence indication,
  • resistance of coding resistor R_C,
  • measurements of grounding R_E.
• EVSE analysis – diagnostics:
  • CP+, CP- voltage,
  • frequency f (PWM),
  • signal filling D (PWM),
  • maximum charging current I_MAX,
  • graph of CP+, CP-, f, D, I_MAX,
  • t_off off time,
  • t_on on time.
• EVSE analysis – simulation of errors (ICCB, EVCS):
  • CPsh – short circuit of CP to PE,
  • Dsh – diode short circuit,
  • PEop – interruption in PE.
• EVSE analysis –s imulation of power supply circuit faults (ICCB):
  • L1op – interruption in phase L1,
  • L2op – interruption in phase L2,
  • L3op – interruption in phase L3,
  • Nop – interruption in N,
  • PEop – interruption in PE,
  • L↔PE – interchanged L and PE wires,
  • U_EXT(PE) – voltage on PE wire.
• EVSE analysis – transition time between states.
