CHARGE AUTHORIZATION CODES

In order to operate a “Liberty Enabled” EV charger, the driver needs to have a Charge Authorization Code. There are three ways to receive a code:

  • Directly from the EV charger owner/operator
  • From a “Liberty Enabled” parking payment kiosk
  • From a pay-by-cell parking payment system

EV CHARGING PROCEDURE

EV charging with a “Liberty Enabled” EV charger consists of the following steps:

  • Remove the connector from the EV charger dock.
  • Plug the connector into the charging port on the EV.
  • Enter the code at the keypad on the EV charger.

Once you have finished charging, remove the connector from the vehicle and put it back into the dock.


TROUBLE SHOOTING

Remember that EV charging is made up of three interrelated but separate components:

  • The EV charger
  • The Liberty Synchronous Codes™ System (i.e. the keypad)
  • the EV

The first task is to identify which component is malfunctioning. We do this by working with the driver to answer the following questions:

  1. Is the charger receiving power?
  2. Did the customer type in the correct code?
  3. Did the Liberty system accept the code?
  4. Did the EV charger activate after the code was accepted?
  5. Is the car receiving power?

The next section uses the “Problem – Solution” format to identify and solve common problems that may arise when using the PBP charging system.

Problem: The Charging light on the charger does not pulse on and off* when the EV is connected.

Possible Reason Solution
The EV is not connected properly. Remove and try again. Confirm the Charging light is pulsing properly.**
There is a technical problem with the charger, connector, or the EV. Confirm the red Protection light is not on. Have the customer try a different charger (if available). Have the customer contact the PBC vendor for a refund. Contact maintenance personnel to inspect the charger.

*Note: The charger uses a pilot signal to detect the EV and confirm it’s ready for charging. A pulsing green light means the charger detects the EV. A solid green light means the charger is operating.

**Note: Tesla EVs must use the J1772 adapter that comes with the vehicle.


Problem: There are no sounds and flashing LEDs when numbers on the keypad are pressed.

Possible Reason Solution
The station is not receiving power or detects an unsafe condition. Confirm the green Charging light is not lit or pulsing. Confirm if the red Protection light is on. Have the customer try a different charger (if available). Have the customer contact the PBC vendor for a refund. Contact maintenance personnel to inspect the charger.
The keypad is not synchronized. Perform a Clock Synchronization procedure then issue a short term code to the customer (see below procedure).


Problem: There is a flashing red LED and a “raspberry” sound when the code is entered.

Possible Reason Solution
The customer entered the wrong code. Check the code and re-enter it.
The keypad is not synchronized. Perform a Clock Synchronization procedure then issue a short term code to the customer (see below procedure).


Problem: After entering the authorization code the charging session does not start.

Possible Reason Solution
The driver entered a wrong code (and heard a “raspberry” sound). Check the code and re-enter it.
The driver did not push the # sign after your 8-digit code. Re-enter your code, followed by the # sign. Even if you entered wrong digits, continue entering the right code*
The small green LED above the keypad does not stay lit. Perform a Clock Synchronization procedure then issue a short term code to the customer (see below procedure).

*Note: The charger will only read the last 8 digits you entered after you hit the # sign.


Problem: The Charging light is on (steady) but the EV is not charging.

Possible Reason Solution
There is a technical problem with the car. Ask the customer if they have any timer settings activated on the vehicle or if the key is in the ignition. If yes then remove the key and/or reset the timer setting. Have the customer try a different charger (if available). Advise the customer to take the car to his dealer to confrim proper operation of the vehicle charger

CLOCK RE-SYNCHRONIZATION PROCEDURE

  1. Have the customer locate the Liberty ID# on the charger. This is a 6 digit number starting with 021xxx and is usually on a blue sticker below the keypad or on the side of the charger body. Record this number.
  2. Go to the LAT website, (www.libertyaccesstechnologies.com), log in with your username and password and click on the Generate Codes button.
  3. Click on Generate Clock Synchronization Code and then select the appropriate Liberty ID# of the charging station you are resynchronizing.
  4. Click the "Generate Clock Synchronization Code" box.
  5. You will be issued two 8-digit codes.

Note: The Clock Synchronization codes set the clock in the charger and should be entered within minutes of generating the codes in order for the clock to be accurate.

  1. Using the keypad, have the customer enter each of the 8-digit numbers, followed by the “#” sign. There is a “raspberry” sound and the red and green LEDs above the keypad will flash after the first number is entered and a long beep after the second code sequence is entered, indicating that the clock is set. If you make a mistake entering the numbers at any time, just start over with the first number.
  2. Manually Issue the customer a Charge Authorization code (see below).
  3. If the customer does not get the long “beep” sound, or the keypad is unresponsive (i.e. no green LED flash when a number is entered) contact Liberty Customer Support for (310) 439-9119

MANUAL CHARGE CODE GENERATION PROCEDURE

  1. Click on the Generate Charging Code button.
  2. Select the appropriate Liberty ID#.
  3. Set the Duration of the charging code.
  4. Click the “Now” button in Date and Time.*
  5. Click on Generate Charging Code.
  6. Read the 8 digit code to the customer and have them enter the code on the keypad.

Note: Clicking the “Now” button means the code will be effective starting with the current time and date. Clicking the “Future” button permits you to issue a code that will be effective at some future date and time.

REGISTRATION

In order to pay for EV charging with a smartphone, the driver needs to be a registered customer of the pay-by-cell (PBC) vendor selected by the owner of the charging station(s). There are two ways to register:

  • on the PBC vendor’s website; or
  • via the PBC vendor’s app.

NOTE:PBC vendors also provide a toll free number to call for assistance or to register a new customer.


PBC EV CHARGING PROCEDURE

Pay-by-cell EV charging is a straightforward process that consists of the following steps:

  • Remove the connector from the EV charger dock.
  • Plug the connector into the charging port on the EV.
  • Launch the PBC smartphone app
  • Enter the appropriate parking space #, EV charger #, or scan the QR code
  • Pay for charging and receive an authorization code.
  • Enter the code on the keypad mounted on the EV charger.

Once you have finished charging, remove the connector from the vehicle and put it back into the dock.


TROUBLE SHOOTING

Remember that PBC EV charging is made up of four interrelated but separate components:

  • The EV charger
  • The PBC system
  • The Liberty Synchronous Codes™ System (i.e. the keypad)
  • The Electric Vehicle itself

The first task is to identify which component is malfunctioning. We do this by working with the driver to answer the following questions:

  1. Is the charger receiving power?
  2. Does the charger recognize the vehicle?
  3. Did the PBC system generate the correct code?
  4. Did the customer type in the correct code?
  5. Did the Liberty keypad accept the code?
  6. Did the EV charger activate after the code was accepted?
  7. Is the car receiving power?

The next section uses the "Problem – Solution" format to identify and solve common problems that may arise when using the PBC charging system.

Problem: The Charging light on the charger does not pulse on and off* when the EV is connected.

Possible Reason Solution
The EV is not connected properly. Remove and reconnect. Confirm the Charging light is pulsing properly.**
There is a technical problem with the charger, connector, or the EV. Confirm the red Protection light is not on. Have the customer try a different charger (if available). Have the customer contact the PBC vendor for a refund. Contact maintenance personnel to inspect the charger

*Note: The charger uses a pilot signal to detect the EV and confirm it’s ready for charging. A pulsing green light means the charger detects the EV. A solid green light means the charger is operating.

The keypad is not synchronized. Perform a Clock Synchronization procedure then issue a short term code to the customer (see below procedure).


Problem: The transaction does not go through.

Possible Reason Solution
There was a cell phone network communication issue. Try again.
Your payment card is out of funds. Contact the PBC vendor.


Problem: After entering the authorization code the charging session does not start.

Possible Reason Solution
The driver entered a wrong code (and heard a “raspberry” sound). Have the driver confirm the code and re-enter it.
The driver did not push the # sign after entering the authorization code. Re-enter the code, followed by the # sign.*
The small green LED above the keypad does not stay lit Perform a Clock Synchronization procedure then issue a short term code to the customer.

*Note: The keypad will only look at the last 8 digits that were entered before the # key is pushed. If the driver hits a wrong digit just have them start over and hit the # sign.



Problem: The Charging light is on (steady) but the EV is not charging.

Possible Reason Solution
There is a technical problem with the car. Check to see if the customer has the vehicle charging profile set correctly (i.e. no delay). Have the customer try a different charger (if available). Have the customer contact the PBC vendor for a refund.
