Cyrix Li-ion Battery Coupler Series: Li-Charge

Operation of the Cyrix Li-Charge

The Cyrix Li-Charge connects a battery charger with a 3-second delay:

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

   

  The Cyrix Li-Charge switches off immediately if its control input reaches the "free floating" state (open circuit), or if it detects overvoltage or overtemperature of a cell. Generally, an overvoltage alarm is reset shortly after charging stops.
  The Cyrix then reconnects the charger after a 3-second delay. After two attempts to reconnect the device at 3-second intervals, this delay is extended to 10 minutes. Whenever the battery voltage is below 13.5 V (or 27 V or 54 V), the Cyrix switches off after a 1-hour delay.
  Note 1: If the discharge current is zero or very low, the Cyrix will not switch off shortly after the charger is switched off and/or disconnected because the battery voltage remains above 13.5 V.
  Note 2: If the output of the battery charger immediately rises back to 13.7 V or more after the Cyrix has switched off, the Cyrix will switch back on after a 3-second delay.
