Combinador de baterias VICTRON ENERGY Cyrix-Li-Charge 24/48 V-230 A (CYR020230430)

The Cyrix-Li-Charge 24/48V-230A battery combiner from Victron Energy (MPN CYR020230430) for 24V and 48V LiFePO4 batteries. It can operate with a maximum current of 230A and is, among other things, an ideal supplement to the VE.Bus BMS as a battery switch for loads that the VE.Bus BMS cannot switch independently.

• Function of the Cyrix battery combiners in general

The Victron Cyrix-Li-Charge 24/48V-230A is a high-performance microprocessor-controlled relay that automatically connects batteries in parallel when one of them has reached a predetermined voltage value (indicating that the battery is being charged) and disconnects the batteries again when the voltage drops below the float voltage value (indicating that one or both batteries are being discharged). Cyrix battery combiners are excellently suited to replace diode isolators. Their main feature is that there is practically no voltage loss, so that the output voltage of the alternators or battery chargers does not need to be increased.

• Operation of the Cyrix-Li-Charge 24/48V 230A

The Cyrix-Li-Charge 24/48V-230A connects a battery charger with a delay time of 3 seconds

• when the "Charge Disconnect" output of the VE.Bus BMS is high and

when it measures 13.7 V (or 27.4 V or 54.8 V) or more at its battery charger terminal and

when it measures 2 V or more at its battery terminal (the Cyrix remains open if it is not connected to the battery).

The Cyrix-Li-Charge disconnects immediately when its control output reaches the "free floating" state (open circuit), indicating a cell overvoltage or a cell overtemperature. In general, a cell overvoltage alarm is reset shortly after charging stops. The Cyrix then reconnects the charger. After two attempts to reconnect the device at intervals of 3 seconds, this delay time extends to 10 minutes. Whenever the battery voltage drops below 13.5 V (or 27 V or 54 V), the Cyrix disconnects with a delay time of 1 hour.

• Note 1: If the discharge current is 0 or only a very small discharge current is present, the Cyrix does not disconnect 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 rises immediately to 13.7 V or more after the Cyrix has disconnected, the Cyrix reconnects with a delay time of 3 seconds.
• Important technical features
• For 24V and 48V battery voltage
• Cyrix-Li-Charge as a perfect supplement to the VE.Bus BMS

A central core of the protection measures for Victron LiFePO4 batteries is the VE.Bus BMS. However, not all loads or chargers can be controlled directly via the VE.Bus BMS. To disconnect such loads or chargers, several VE.Bus BMS controllable Cyrix switches are available.
