Hello Victron Community,
We have the Lynx Smart BMS connected to one 12,8V / 200Ah Lithium battery. I think usually the battery capacity used with the Lynx Smart BMS 500 is bigger. Therefore the capacity reserve after going into hibernation mode is also bigger.
In our case the Lynx Smart BMS discharges the battery down to 8,5V before it powers completely off. Power consumption in hibernate mode 12V system is 0.25mA - 0.35mA .
MY QUESTION:
Will it be possible to self adjust the discharge floor for smaller battery capacities & switching Bluetooth off to lower the Power consumption in hibernate mode?
The best option would be that the user could self adjust the discharge floor parameter higher than 15% himself. For safety reasons the minimum discharge floor parameter can be 15%.
Relavant passages from the manual:
"Discharge floor The “Discharge floor” parameter is used in the time remaining calculation. The battery monitor calculates the time it takes until the set “discharge floor” has been reached. It is also used to set the state of charge alarm defaults. The discharge floor parameter is fixed at 15%."
"9.3.7. System in sleep or hibernate mode This is indicated by the status LED off and the Bluetooth LED flashing every 3 seconds. The Lynx Smart BMS goes into sleep or hibernation mode once the battery or a battery cell has been deeply discharged. The Lynx Smart BMS will conserve as much power as possible, to not discharge the battery much further. Bluetooth is still active, but other non-essential circuits are turned off, including the power to the Lynx Distributor(s). Check the voltages of the connected batteries and if they are low, charge the batteries. As soon as the Lynx Smart BMS sees a charge voltage it will automatically re-activate and close its contactor to allow for battery charging."
"Hibernation mode The Lynx Smart BMS is in hibernation mode when the Lynx Smart BMS has turned itself off because of a low battery event or when it has been turned off via the remote on/off switch. In hibernation mode, the contactor and most of the electronic circuits are turned off and the power consumption is very low (0.8mA). The status LED is off. The power to the Lynx distributor(s) is turned off. Bluetooth is still active during hibernation mode. The blue Bluetooth LED is either flashing every 3 seconds or is on, depending on whether there is an active Bluetooth connection with the VictronConnect app. The Lynx Smart BMS will come out of hibernation mode when the remote on/off switch is switched on or the batteries are charged."
