Slow charging(on-board)

Individual poles at home or at parking lotsFull battery charge >6 hours

2 - 4 kW, normal residential & office installationsSmall converters

Fast charging(on-board)

Special charging stations / special equipment at homeNow fastest charge ca. 30 min, typical 1 hr

7.2 - 43 kWOnboard converter becomes expensive component for higher powers

Fast and Ultra-fast charging(off-board)

Special charging stations (option: integration of energy storage)Concept to reduce charging time to ca. 6 minutes – near parity with ICE refueling

50 - 250 kW+Off-board DC convertersImproved performance, lower system costs

Battery replacement

Stations for replacement of depleted batteries Main application: highways

Larger stations on the MW rangeMV installations and larger convertersVision: robotic solution to replace batteries

EV Charging poleCar Charging Outlet Unit (charger) - Definition

§ A charger is an access point to electric power.§ The access is provided through a plug and socket combination.§ The energy consumption is measured by an electric meter function.§ The energy flow is controlled by a switching device (on/off)§ The charger (socket) is protected by short circuit, overload and residual

current protection.§ Overvoltage protection by surge protection devices can be provided if

required.§ Authentication devices (RFID transponder/tag, credit card reader)§ A communication function (eg. GPRS) exchanges information between

charger and system.§ A control function does:

§ authentication (in interaction with the management system),§ provides the measured/consumed charged electricity to the

management system,§ provides monitoring/diagnostics of the charger

§ Above components are housed in a charge pole

EV Charging poleClassification of Charge spots

§ Home/residential

§ In-house (garage) or outdoor (street parking, car port)

§ No authentication necessary

§ Energy measurement (sub-metering) and control part of the SmartHome

§ Few charge points per home / flat

§ Business, Public (outdoor, indoor)

§ Company parking

§ Public building, stores, malls

§ Car parks

The product structure of a charge pole can be broken down in the following functional areas:

§ Standard components for electrical distribution (RCBO, MCB, etc)

§ Standard components for automation/communication (PLC, Meter, KNX modules, etc.)

§ Socket outlet / Coupler§ Additional functions (authentication, communication, HMI, etc)

§ System Integration level 1: communication with PLC

§ System Integration level 2: user interface, billing

§ External case

Development of a charge pole is organized accordingly

AC500-eCo PLC§ Authentication of the user by

RFID-chip, verification with service provider, allow or refuse charging

§ Read out of charged electricity and communicate it with the service provider using wireless GPRS communication or build-in Ethernet (cable) or other fieldbus

§ Load control and charger status (available, occupied, out of service, charge current)

§ Communication with the Electric Vehicle for safe connection and correct charging

§ Allows remote diagnostic of charger

§ Either resets automatically in a defined sequence or controlled by the AC500

§ Monitoring if tripped

Electricity meter§ Measures the charged electric

power (single phase or 3-phase)

§ Measures actual line voltage and actual charge current

Electricity meter

AC Charge poleDistribution/automation components

§ Electronic meter with four quadrant metering meaning that the meter can measure both imported as well as exported energy for active or active and reactive energy

§ Type approved according to international standards. Approved according to MID

§ Class B and A according to EN 50470-1, -3, Class 1 and 2 according to IEC

§ Remote reading via pulse output or communication

§ Communication via infrared port or via built-in interface Communication modules that connect via infrared port to the meter for remote reading and setting of data in the meter

AC Charge poleElectricity meter

User identification and authorization to charge could be managed through:

§ Sinopec card (中国石化加油卡)

§ ATM card (connection to the bank server required)

§ Beijing “all-in-one” card (市政交通一卡通)

§ Credit card (VISA, AMEX, etc)

§ Any other system to be defined according to the local habits/needs
