Description

Victron Energy 's Cyrix-Li-Charge 12/24V-120A battery coupler (MPN CYR010120430) for 12V and 24V LiFePO4 batteries. It can work with a maximum current of 120A and is, among other things, an ideal addition to the VE.Bus BMS as a battery switch for loads that the VE.Bus BMS cannot switch independently.

Function of the Cyrix battery couplers in general

The Victron Cyrix-Li-Load 12/24V-120A is a high performance microprocessor controlled relay that automatically connects batteries in parallel when one of them has reached a predetermined voltage level (indicating that the battery is being charged) and which recharges the batteries disconnect when the voltage falls below the float voltage level (indicating that one or both batteries are being discharged). Cyrix battery couplers are ideal for replacing isolating diodes. Their main feature is that there is practically no loss of voltage, so there is no need to increase the output voltage of the alternators or battery chargers.

How the Cyrix-Li-Charge 12/24V 120A works

The Cyrix-Li-Charge 12/24V-120A connects a battery charger with a delay time of 3 seconds:

  • if the "Charge Disconnect" output of the VE. Bus BMS is high and
  • if it measures 13.7 V (respectively 27.4 V or 54.8 V) or more at its battery charger connection and
  • if it measures 2V or more on its battery connection (the Cyrix will remain open when not connected to the battery).

The Cyrix-Li-Charge shuts down immediately if its control output reaches a "free floating" (open circuit) state, indicating cell overvoltage or cell overtemperature. In general, an over-cell alarm will reset shortly after charging stops. The Cyrix then reconnects the charger. After two attempts to reconnect the device, 3 seconds apart, this delay time increases to 10 minutes. Whenever the battery voltage is below 13.5 V (or 27 V or 54 V), the Cyrix switches off after 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 switch off shortly after the charger is switched off and/or disconnected because the battery voltage remains above the 13.5V value. Note 2: If the output of the battery charger immediately rises back to 13.7V or more after the Cyrix has switched off, the Cyrix will switch on again with a delay time of 3 seconds.

Cyrix-Li-Charge as a perfect complement to the VE.Bus BMS

A key piece of protection 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 switch off such loads or chargers, several VE.Bus BMS controllable Cyrix switches are available.
