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 over voltage 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 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.


Cyrix-Li-ct

The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct. The Cyrix-Li-ct will parallel connect a lead acid starter battery and a LiFePO4 battery:

-if the Charge Disconnect output of the VE.Bus BMS is high, and

-if it senses 13,4V (resp. 26,8V) or more on one of its power terminals.


The Cyrix will disengage immediately:

-when its control output becomes free floating, signalling cell over voltage or cell over temperature, and/or

-when battery voltage drops below 13,2V.

Start assist function: a short positive pulse will close the relay during 30 seconds. A built-in transient voltage suppressor will limit the voltage spike that may occur when the Cyrix suddenly
