What is battery monitor and its feature

The ability to accurately read a battery energy percentage is satisfying. Information on the battery’s charge helps with its utilization and planning. A tool like the battery monitor displays the battery’s charge.This article will focus on the battery monitor. It will explore how it works, its features, and how it is applied.

What is battery monitor

A battery monitor is a device that displays the SOC (State of Charge) of a battery. Additionally, it also retrieves and displays battery temperature, estimated battery runtime, battery voltage, and power consumption. Our common powerwall battery or ups or power exchange cabinet will have a battery monitoring system, which can monitor the battery health status remotely in real time. Nowadays, batteries in many application scenarios do not need to use devices to measure the battery status. The battery pack itself has a battery display screen to show the working status of the battery and so on.

How a battery monitoring system works

In this system, monitoring sensors are placed at each battery. The sensors measure the voltage levels of each cell during charging and discharging. These readings are sent to the monitoring system controller from where they are transferred to the battery monitoring software. Next, the software converts this raw data into readable forms that a user can easily understand and sends it as alerts to the user.

Battery monitoring collects information through the “brain” battery management system of the battery, such as input and output voltage, current, electrical properties of each single battery, internal resistance, battery capacity and battery temperature, etc., and can quickly locate faulty batteries. Now there is also a 12v 100ah lithium ion battery of Bluetooth type, which is convenient for users to use the mobile phone to check the battery status in real time. There is no need to take out the battery test, and various battery data can be seen on the mobile phone at a glance.

Is a battery monitoring necessary

Yes, it is. Unless one has the tools to measure a battery SOC at any given point, a battery monitor shows you real-time battery conditions. Its settings allow you to make adjustments to collect more accurate or specific data.

With access to battery data, one can plan on battery utilization. Additionally, this information helps extend a battery’s life as one can take better care of it through charging and recharging. It can also warn of bad batteries, quickly identify problems, and prevent potential failures from battery bulging and performance degradation.

The feature of the battery monitor

Easy installation
Battery monitors are easy to connect with a battery system.
Safety features
Battery monitors should have inbuilt safety precautions such as a fuse to aid in cases like short circuits.
Real-time display of data
A good battery monitor should display its battery readings immediately after changing or updating.
A battery monitor should be compatible with the system whose information it reads, e.g., If you have a lithium ion battery with 12V, get a battery monitor that can read and display that battery’s data.
Auto alert system
One should be able to custom-make alert notifications, such as when the SOC is at a particular level. These alerts are sent automatically.
Low power consumption
Battery monitors should consume low power.

The application scenarios of battery monitor

Battery monitors have several applications, including:

lithium battery pack
Battery monitoring systems are used in lithium-ion batteries to check the condition of charging and discharging. Specifically, they take temperature, voltage, and charge state variations to balance the battery’s state.

Home energy storage system
Whether it is powerwall wall mounted or stacked, there will be a master controller to collect battery data and display the information of each battery pack on the battery monitoring screen. It is to allow users to easily monitor the battery and allow manufacturers to quickly determine battery problems and provide solutions.

Used in vehicles
In a vehicle, a battery monitor is used as an interface to show the state of its battery’s electronic components. Additionally, the battery monitor optimizes the accumulator’s performance and life by controlling temperature levels.

Used in UPS
Common high-voltage UPSs increase the voltage when connected in series. To maintain the balance of the batteries, each battery pack needs to have a BMS. There is a controller that collects information through the BMS of each battery pack to display the working status of the battery pack and various data. on the controller’s display.

The difference between a lithium battery monitor and a lithium battery protector

Unlike a lithium battery monitor used to display a battery’s information, a lithium battery protector protects against overcharging and over-discharging. Moreover, lithium battery protectors detect and aid against overcurrent, overvoltage, under voltage, extreme temperatures, and short circuits. Lithium battery protectors are essential for lithium-ion battery packs. Similar to battery monitors, battery protectors extend a battery’s life.

What is the best 12v lithium battery monitor

There are several good 12V lithium battery monitors. However, according to several retailers and users, the battery with monitoring display is the best. Now many battery manufacturers, including TYCORUN ENERGY, can customize the battery pack with LED screen for customers, which can display the usage data and status of the battery, there is also the aforementioned Bluetooth 12v lithium battery

On top of that, this shunt-based lithium battery monitor is reasonably priced, easy to install, and more accurate than its competitors. Additionally, it has a feature that allows you to connect it to your smartphone via Bluetooth, thus easier access to battery data. Also, some models in the BMV-700 series have an additional input that displays results from another battery.

What is the importance of battery monitoring

I.It helps to extend a battery’s life.
II.Due to the constant updates on the SOC of the battery, you are able to take better care of it therefore reducing maintenance costs.
III.It helps with quick identification of potential fault areas which enables faster problem solving.
IV.The system keeps a historical record of the battery data. These data can be used make informed decisions regarding the battery.
V.Information on the state and health of a battery helps in alleviating costly losses.


Battery monitors are necessary for today’s business climate as they can elevate you ahead of competitors. Moreover, the ability to quickly read and interpret data from battery monitors enables consumers to take better care of their batteries.
