10.1.8. EvseManager¶
EVSE Manager. Grid side power meter: Will be used for energy management. Will also be used for billing if no car side power meter connected. Car side powermeter: Will be used for billing if present.

10.1.8.1. Module Configuration¶
connector_id:integer
Connector id of this evse manager
evse_id:string
default: DE*PNX*E1234567*1
EVSE ID
evse_id_din:string
default: 49A80737A45678
EVSE ID DIN after DIN SPEC 91286
payment_enable_eim:boolean
default: True
Set to true to enable EIM (e.g. RFID card or mobile app) authorization
payment_enable_contract:boolean
default: True
Set to true to enable contract (aka plug and charge) authorization
ac_nominal_voltage:number
default: 230
Nominal AC voltage between phase and neutral in Volt
ev_receipt_required:boolean
default: False
Unsupported: request receipt from EV with HLC
session_logging:boolean
default: False
Enable/Disable session log file output
session_logging_path:string
default: /tmp
Output directory for session log files
session_logging_xml:boolean
default: True
Log full XML messages for HLC
three_phases:boolean
default: True
Limit to three phases (true) or one phase (false)
has_ventilation:boolean
default: True
Allow ventilated charging or not
country_code:string
default: DE
Country Code
rcd_enabled:boolean
default: True
Enable or disable RCD
max_current_import_A:number
default: 32
User configurable current limit for this EVSE in Ampere
max_current_export_A:number
default: 32
User configurable current limit for this EVSE in Ampere
charge_mode:string
default: AC
Select charging mode
enum: AC, DC
ac_hlc_enabled:boolean
default: False
Enable or disable HLC (aka ISO15118) for AC mode
ac_hlc_use_5percent:boolean
default: False
Use 5 percent PWM signalling to try to enforce HLC on AC. Note that if EIM arrives before SLAC matching, we will fall back to nominal PWM charging. So most cars will never use HLC in this mode, especially on a free service where EIM is always available, but that is what ISO15118-2/-3 requires to be compliant - it wants to use HLC only for PnC and not for EIM.
ac_enforce_hlc:boolean
default: False
Combine with 5percent option to really enforce HLC even with EIM. It is not ISO15118-2/-3 compliant as it waits for matching even if EIM is available before SLAC reaches matched state. On cars that do not support ISO15118 on AC this will take a very long time to timeout and fall back to basic nominal PWM charging, but it will eventually.
ac_with_soc:boolean
default: False
Special mode that switches between AC and DC charging to get SoC percentage with AC charging
dc_isolation_voltage_V:integer
default: 500
DC voltage used to test isolation in CableCheck. Set to 500V.
dbg_hlc_auth_after_tstep:boolean
default: False
Special mode: send HLC auth ok only after t_step_XX is finished (true) or directly when available (false)
hack_sleep_in_cable_check:integer
default: 0
Hack: Sleep for n seconds at the end of cable check.
hack_sleep_in_cable_check_volkswagen:integer
default: 0
Hack: Additional sleep for Volkswagen cars for n seconds at the end of cable check
switch_to_minimum_voltage_after_cable_check:boolean
default: False
When cable check is completed, switch to minimal voltage of DC output. Normally disabled.
hack_skoda_enyaq:boolean
default: False
Skoda Enyaq requests DC charging voltages below its battery level or even below 0 initially. Set to true to enable dirty workaround.
hack_present_current_offset:integer
default: 0
Adds an offset [A] to the present current reported to the car on HLC. Set to 0 unless you really know what you are doing.
connector_type:string
default: IEC62196Type2Cable
Type of charging connector available at this EVSE
enum: IEC62196Type2Cable, IEC62196Type2Socket
hack_pause_imd_during_precharge:boolean
default: False
Disable IMD at the end of CableCheck and re-enable when current is flowing in CurrentDemand. Some DCDC power supplies do not start current flow when insulation measurement is active. Set to true to enable dirty workaround for some IMD hardware.
hack_allow_bpt_with_iso2:boolean
default: False
Hack. Allow bidirectional power transfer with DIN spec and ISO-2. Currents communicated on HLC will always be positive but power supply may actually discharge the car.
autocharge_use_slac_instead_of_hlc:boolean
default: False
Use slac ev mac address for autocharge instead of EVCCID from HLC
logfile_suffix:string
default: session_uuid
Use the string given for the log folder name. Special string session_uuid will be replaced with session uuid.
soft_over_current_tolerance_percent:number
default: 10.0
Allow for N percent over current in soft over current checking during AC charging.
soft_over_current_measurement_noise_A:number
default: 0.5
Set current measurement noise. Added to limit as an offset to avoid false triggers.
hack_fix_hlc_integer_current_requests:boolean
default: False
Some cars request only integer ampere values during DC charging. For low power DC charging that means that they charge a few hundred watts slower then needed. If enabled, this will charge at full power if the difference between EV requested current (integer) and HLC current limit is less then 1.0
