42. The charger confirms with ChargeParameterResponse. The contains the limits from charger side, e.g. min and max voltage,
|
||||
min and max current. Now, the initialization phase of the charging session is finished.
|
||||
43. The car changes to CP State to C or D, by applying an additional resistor between CP and ground.
|

43. The car sends CableCheckRequest. This contains the information, whether the connector is locked.
|

44. The charger confirms with CableCheckResponse.
|
||||
45. The car sends PreChargeRequest. With this, the car announces the target voltage of the charger before closing the circut. The goal
|
||||
is, to adjust the chargers output voltage to match the cars battery voltage.
|
||||
46. The charger confirms with PreChargeResponse. This response contains the actual voltage on the charger.
|

47. The car sends PowerDelivery(Start)Request.
|

48. The charger confirms with PowerDeliveryResponse.
|

49. The car sends CurrentDemandRequest (repeated while the charging is ongoing). In this message, the car tells the charger the target voltage and
|

target current.
|

50. The charger confirms with CurrentDemandResponse. This contains the measured voltage, measured current, and flags which show which limitation
|

44. The car sends CableCheckRequest. This contains the information, whether the connector is locked.
|

46. The charger confirms with CableCheckResponse.
|
||||
47. The car sends PreChargeRequest. With this, the car announces the target voltage of the charger before closing the circut. The goal
|
||||
is, to adjust the chargers output voltage to match the cars battery voltage. Also a current limit (max 2A) is sent.
|
||||
48. The charger confirms with PreChargeResponse. This response contains the actual voltage on the charger.
|
||||
49. The charger adjusts its output voltage according to the requested voltage.
|
||||
50. The car measures the voltage on the inlet and on the battery. If the difference is small enough (less than 20V?), the car
|
||||
closes the power relay.
|
||||
51. The car sends PowerDelivery(Start)Request.
