Contains attributes that can be exposed by PEVs and other devices that have charging requirements.
Fields§
§charging_power_now: ActivePower
This is the actual power flow in or out of the charger or inverter. This is calculated by the vehicle based on actual measurements. This number is positive for charging.
energy_request_now: RealEnergy
This is the amount of energy that must be transferred from the grid to EVSE and PEV to achieve the target state of charge allowing for charger efficiency and any vehicle and EVSE parasitic loads. This is calculated by the vehicle and changes throughout the connection as forward or reverse power flow change the battery state of charge. This number is positive for charging.
max_forward_power: ActivePower
This is maximum power transfer capability that could be used for charging the PEV to perform the requested energy transfer. It is the lower of the vehicle or EVSE physical power limitations. It is not based on economic considerations. The vehicle may draw less power than this value based on its charging cycle. The vehicle defines this parameter. This number is positive for charging power flow.
minimum_charging_duration: Uint32
This is computed by the PEV based on the charging profile to complete the energy transfer if the maximum power is authorized. The value will never be smaller than the ratio of the energy request to the power request because the charging profile may not allow the maximum power to be used throughout the transfer. This is a critical parameter for determining whether any slack time exists in the charging cycle between the current time and the TCIN.
target_state_of_charge: Percent
This is the target state of charge that is to be achieved during charging before the time of departure (TCIN). The default value is 100%. The value cannot be set to a value less than the actual state of charge.
time_charge_is_needed: TimeType
Time Charge is Needed (TCIN) is the time that the PEV is expected to depart. The value is manually entered using controls and displays in the vehicle or on the EVSE or using a mobile device. It is authenticated and saved by the PEV. This value may be updated during a charging session.
time_charging_status_pev: TimeType
This is the time that the parameters are updated, except for changes to TCIN.
