Lead acid batteries are typically used in the automotive industry, where they provide a high current pulse to start the vehicle, in traction applications, where they undergo periodic deep discharge and charge, and in stationary applications, where they remain in charged state most of their life. They are used also in hybrid electric vehicles (HEVs) and in remote area power
The values of the resistors are R1 = 56K, R2 = 120K + 47K, R3 = 3K9 to give us an 11.89V to 12.65V voltage range – i.e. the first red LED (D1) will light up at a voltage of 11.89V which is a virtually empty 12V lead acid battery, and the last green LED (D10) will light up at a voltage of 12.65V corresponding to a full 12V lead acid battery.
As soon as the battery monitor detects that the voltage of the battery has reached the set “ Charged voltage ” parameter and the current has dropped below this “Tail current” parameter for a certain amount of time, the battery monitor will set the state of charge to 100%. 7.2.5. Charged detection time
To calibrate the monitor, connect it to 12.65V and adjust the 10K potentiometer (VR1) until the last green LED turns on. With the resistor values used, you will just need to check that the first red LED turns off as it should at 11.89V. The LM3914 has two modes – DOT and BAR.
7.4. Alarm settings The BMV battery monitor is equipped with an alarm relay and a buzzer. Alarms are also visible on the VictronConnect app while connected to the battery monitor or are used to send an alarm signal to a GX device. Alarms are disabled by default.
For example, if the actual long-term current is 0.0A and, due to injected noise or small offsets, the battery monitor measures 0.05A the battery monitor might, in the long term, incorrectly indicate that the battery is empty or will need to be recharged.
The real-time alarm allows you to make quick responses to battery issues and thus to avoid costly business loss. With voltage equalization/balancing feature, the uptime of battery backup can be maximised and costs of maintenance & replacement can be minimised.
