Cyrix-Li-Charge 24/48V – 230A

Cyrix-Li-Charge

The Cyrix-Li-Charge will connect a battery charger with 3 seconds delay:-

• if the Charge Disconnect output of the VE.Bus BMS is high, and
• if it senses 13,7V (resp. 27,4V or 54,8V) or more on its battery charger connection terminal, and
• if it senses 2V or more on its battery terminal (the Cyrix will remain open, if not connect to the battery).

The Cyrix-Li-Charge will disengage immediately whenever its control input becomes free-floating, signalling cell over voltage or cell over temperature. In general, a cell overvoltage alarm will reset shortly after charging has been stopped. The Cyrix will then reconnect the charger after a delay of 3 seconds.

After two attempts to reengage with 3 seconds delay, the delay increases to 10 minutes. Whenever the battery voltage is less than 13,5V (resp. 27V or 54V), the Cyrix will disengage with a delay of 1 hour.

Note 1: In case of zero discharge current, or a small discharge current, the Cyrix will not disengage shortly after the charger has been switched off and/or disconnected, because battery voltage will remain higher than 13,5V.Note 2: If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13,7V or more, the Cyrix will re-engage, with 3 seconds delay.
