Solved: False low battery voltage alerts

I have an ESS installation with Multiplus-II 48/5000 and Seplos battery connected via CAN. In low battery SOC (~15%) I see tons of ''Low battery voltage'' alerts at rather high voltages (51.25V). DVCC is enabled (with SVS). In the Seplos BMS I don''t see any warnings.

MultiPlus-II sudden low battery alarm while battery is full (BSL

The battery once again gave a low voltage alarm while about 80% SoC, causing the inverter to restart. There is clearly something wrong. My best guess (based on many informed opinions) is a serious BMS firmware bug or design flaw. It could also be severely unbalanced cells, or a faulty cell.

Low Battery voltage without reason

This voltage is the voltage reported by the Multi RS to Cerbo and Cerbo is only collecting it and sending it to VRM. Also based on this voltage, the Cerbo gives you the alarms. Please check the battery to Multi RS connections. Also any power switches or fuses if you have ones. If you have a bad connection (high resistance) this is

VE.Bus low battery alarm, why?

In an ESS system, low battery warnings (as distinct from alarms) are generated when the voltage drops below the dynamic cut-off level PLUS the restart offset (0.3V for a 12v system). Your "much higher" discharge rates when the alarms occur are only about 20 amps or 0.05C, so the relevant dynamic low voltage cut-off is not much below 12v

Low Battery Voltage Indicator Alarm

A very useful circuit shown here can do this job very effectively by warning when your battery has reached a certain voltage point, for example when it is 90 percent empty, a 12V lead-acid battery shows 11.6. So change the 10 K variable resistor circuit to warn until the battery hits that amount or set the warning circuit when the battery hits

6 FAQs about [Battery voltage low alarm]

What is battery low alarm?

BATTERY LOW ALARM: Hi Everyone, This project sounds alarm when the battery voltage falls below the user defined (low) voltage .It is used in 12 volt battery (It may be any type of Battery- Lead acid ,Lithium -ion, Lithium - Polymer etc.,) and it w

What is a good low voltage for an alarm?

Your “much higher” discharge rates when the alarms occur are only about 20 amps or 0.05C, so the relevant dynamic low voltage cut-off is not much below 12v, and so the alarm voltage is just a little under 12.3V, which is exactly what you are seeing.

How do you set a battery low alarm circuit?

Using DC-DC step down converter or variable voltage source , set the voltage to 10.59 volts. Then connect this 10.59 volt to the Battery low alarm circuit. Adjust R3 multi turn pot in Alarm circuit , clockwise or anticlockwise until buzzer beeps and LED on.Hold on R3.

What is a low battery warning?

Low battery warning starts at cut-off + offset. Your load of around 25A is 0.06C so it's between 0.005C and 0.25C so the cut-off voltage is between 12.00V and 11.65V (closer to 12.00V) and the warning starts 0.3V above that. It's explained in the ESS assistant:

What is a safe low voltage battery?

For instance, Lead acid battery 10.7 Volt is considered as safe low voltage. Here I am setting the voltage of 10.6 volt for demonstration purpose. Besides ,Viewers with some basic knowledge in electronics can do this Project. The total cost of this project would around 3 USD. The componets used in this project are given below: 1. LM358 IC

What happens if the battery voltage is less than 10V?

If the battery has a voltage of less than 10V (20V) or if one of the battery cells has a cell voltage below 2.5V, the battery will have permanent damage. This will invalidate the warranty. The lower the battery or cell voltage is, the more damage to the battery will be.
