Types of Connectors:
Connector Type | Voltage | Amps | Max Power |
Type 2 (Single Phase) | 230V | up to 32A | 7.36kW |
Type 2 (3 phase) | 230V per phase (400V) | up to 32A per phase | 22.08kW |
CCS2 | 200 - 920V | up to 500A | 350kW |
CHAdeMO (1st Gen) | 500V | up to 125A | 62.5kW |
CHAdeMO (2nd Gen) | 1kV | up to 400A | 400kW |
Note: even if the connector can provide the maximum power, the car also needs to be able to receive that much power.
The voltage displayed in the portal is usually the voltage of one phase, in the case of a three phase system.
Some CCS2 connectors can reach max power 400 kW.
The IEC 62196 Type 2 connector is the standard for AC charging within Europe. It usually has the same appearance (picture below) whether the charger provides single or 3 phase charging.
CCS2 (Combined Charge System) is the standard for the European market when it comes to DC charging. They are extensions of the IEC 62196 Type 1 and Type 2 connectors, with two additional direct current (DC) contacts to allow high-power DC fast charging.

How to Calculate the Power Output
To calculate the power output you can use the following formula:
For DC: Power (W) = Voltage (V) * Current (A)
For AC: Power (W) = Voltage (V) * Current (A) * No of phases
or you can use the calculator below:
Types of Electrical Errors
Connector [ConnectorId] has unacceptable voltage [ReportedVoltage]
Explanation: Charger has an out of range voltage output. For AC charger that is usually ±10% the usual 230V (<207V or >253V), but the value that triggers the error can be closer to 230V, depending on the charger manufacturer.
Action: Inform the CPO they need to investigate the supply issue.
Connector [ConnectorId] max_electric_power of [DisplayedPower] is higher than the calculated power of [CalculatedPower]
Explanation: Connector displays a max power output higher than expected.
Action: Adjust the value to the correct max power. Max power can be double checked with the formula above.
Connector [ConnectorId] has format [Socket/Cable] for amperage [Amps]
Explanation: Connector is setup as cable for socket and it should be the other way around. (some power types can't have a socket connection, it must be cable)
Action: Correct the connector by changing the connector type to the correct format, keeping the type (for example changing Type 2 Socket to Type 2 Cable)
Connector [ConnectorId] max_amperage [MaxAmps] exceeds limit of [AmpLimit]
Explanation: Connector has the maximum amperage set higher than the max rated output. (most common 32A per phase AC or 350A DC)
Action: Update the rated value of the max amp output.
