On my lynx smart bms 1000 I use remote 10/11 connected to an emergency switch to disconnect my battery from the system. However when I push the emergency switch it takes about 30 seconds before the connector in the lynx really disconnects my battery. How can I speed up this time to disconnect?
Hi,
I have Lynx BMS NG (very similar to Smart BMS that you have) with a simple emergency stop contact installed as per the right most (4th option) example in the manual (screenshot below), when I press it, it causes the BMS to open the contactor IMMEDIATELY.
Now, one has to be careful with this feature. In my case I damaged some electronics on my boat when I pressed this accidentaly with my elbow, as one of the chargers which does not support DVCC was putting out full current, and when the battery was disconnected there was a voltage spike. So make sure all your chargers are off. The intention is that this REM control is not normally the way to shut down your system, as the Cerbo or Victronconnect shutdown process is more safe for equipment.
What other equipment is connected to your BMS?
It might be that the BMS is sending out a signal to the chargers to stop charging before opening the contactor (DVCC) but my understanding is that it should just send the command and open contactor immediately.
The smart lynx is installed between the battery (Yixiang MB56 35kWh with JKBMS v19.34) and a lynx distributor which is connected with 3x MPII 4k5 (3 phase home installation). The BMS din8 connectors are shortcut because I don’t use Victron Batteries.IN the remote console DVCC is ON, the lynx smart BMS is set as the accumonitor and JKBMS is set as the BMS monitor.
