Cyrix Battery Coupler Li-ion Series: Li-Charge

How the Cyrix-Li-Charge works

The Cyrix-Li-Charge connects a battery charger with a delay time of 3 seconds:

• when the VE. Bus BMS Charge Disconnect output is high and
• if it measures 13.7 V (or 27.4) or more at its battery charger connector and
• when it measures 2V or more at its battery terminal (the Cyrix remains open when not connected to the battery).

  The Cyrix-Li-Charge switches off immediately if its control input reaches the "free floating" state (open circuit), indicates a cell overvoltage or a cell overtemperature.
  Generally, a cell overvoltage alarm will reset shortly after charging is stopped. The Cyrix will then reconnect the charger after a 3 second delay. After two attempts to reconnect the device at 3 second intervals, this delay time will increase to 10 minutes.
  Whenever the battery voltage is below 13.5V (or 27V or 54V), the Cyrix switches off with a delay of 1 hour.
  Note 1: If the discharge current is 0 or there is only a very small discharge current, the Cyrix will not shut down shortly after the charger is turned off and/or disconnected because the battery voltage remains above 13.5 V.
  Note 2: If the battery charger output immediately rises to 13.7V or more after the Cyrix has shut down, the Cyrix will restart with a delay of 3 seconds.
