Hi @jeffbosch1697, charging "levels" are used to categorize the rated power, voltage, and current of the charging system. There are 3 different EV charging levels. Different levels of charging in North America: SAE Configurations. Level-1 - Supply from household outlet - Make use of EV’s on-board charger - 120V 1ph AC; 12-16A - Charging power: 1.4KW or 1.9KW Level-2 - Supply from household outlet or EV Charge point - Make use of EV’s on-board charger - 208-240V 1ph AC ; 12 to 80A (Typ. 30A) - Charging power: 2.5KW to 19.2KW (Typ. 7KW) Level-3 - Supply from 208-600V 3ph AC - Make use of off-board DC fast charger - 400A (Typ. 60A) - Charging power: up to 240KW (Typ. 50KW) Charging "modes" are used to categorize the mode of power delivery, protection installation, and communication/control of the charging system. There are 4 different EV charging modes. Mode-1 - AC Charging - Regular household outlet - Un-safe - Not recommended to use Mode-2 - AC Charging - In-cable control and protection (IC-CPD) - Limited to 3.7kW (16A) in residential use or 7.4kW (32A) for industrial Mode-3 - AC Charging - Control, communications and protection functions incorporated in the charge point (EVSE) - Wide range of charging : 3.7KW to 43KW Mode-4 - DC Charging - Option to either CHAdeMO or CCS - For public and commercial charging applications - Wide range of charging capabilities - over 150kW Charger "types” are used to categorize the different socket-outlets used to deliver power in the charging system. There are many, but majorly 3 different connector types. AC Connectors - Type 1 / SAE J1772 - Type 2 / MENNEKES - Type 3 / SCAME DC Connectors - AA / CHAdeMO - EE / CCS-1 - FF / CCS-2 Tesla Connector (both AC & DC)
Hi I wants to know if there any communication between EV and Charge point to send the connector ID to the CSMS or it just the ocpp that generate the connector ID to send it to the central system ?
Hi Kareem Elgamal, the connector ID is a property of the Charge point connector, and is used in OCPP to identify it. The charge point would then inform if a EV is connected or not, or if a charging session/transaction had started.
Nice video, thanks! Is it a new feature to transmit the battery level via Type2 PWM - thought this can just regulate the power only? V2G uses only DC connections like CHAdeMO yet, right?
Hi, thanks for watching! The Control pilot does not communicate the battery level indeed, it is used to communicate the charging system state, the EV Charging Station's maximum charging current and any errors. The EVCS sets the PWM duty depending on the maximum charging current available and the Control Pilot can work in different states but at the moment, it does not communicate the battery level. Regarding V2G, yes only CHAdeMO is certified in some countries to do this and the CCS seems to have a roadmap where full V2G capability is expected to be completed by around 2025.
Mode 3? Mode 4? I've heard of Level 1 and Level 2 for AC, and DCFC for DC, but not familiar with those modes. Where are they described? Thanks.

for the common 240v uk points, 2 resistors and 1 diode is all the charge point needs to see, and it turns on the 240v.
Nice video, thanks!
