Battery Management System vs. Battery Monitoring System

When buying a battery, we always notice the description of the BMS, usually mentioning its maximum sustainable current, its functions (overdischarge, overcharge, overcurrent, high temperature, short-circuit), but we get confused when we come across another acronym, and today we are going to talk about Battery Management System and Battery Monitoring System. 

Battery Management System

What is it?

The Battery Management System (BMS) is an advanced system for managing and protecting battery packs. BMS boards are installed in all SANFOU LiFePO4 series batteries in order to protect and guarantee the optimal performance of the batteries.
Its functions include monitoring, protection, balancing, control and communication.
It monitors the voltage, current, temperature and state of charge (SOC) of the battery, disconnects the load or charger when the battery parameters exceed the safe range, ensures the balance and stability of the battery, and manages the charging and discharging process to optimize the performance and life of the battery.

Battery Monitoring System

A battery monitoring system is a subsystem or feature that focuses on monitoring the status of your batteries, transforming your battery settings into intuitively visual information. Using it, you can conveniently assess the status and usage of your battery, monitor and analyze your battery usage in real time, similar to the effect of a monitor, which can maintain the health of your battery and avoid lack of power when you are living in RV voyage, off-grid.
Measures and collects data on voltage, current, temperature, SOC and SOH, performs data logging on battery parameters for analysis and diagnostics, provides alarms or warnings if battery parameters exceed predefined safety limits, and can send battery status information to the user or external systems for monitoring and decision making.

Point of difference

1. The functions of a battery-mounted BMS board include monitoring, protection, balancing, control and communication.
A battery monitoring system, on the other hand, focuses on measuring and reporting battery parameters.
2. A BMS actively protects the battery by disconnecting the load or charger, balancing the battery and controlling the charging/discharging process when the battery exceeds a threshold value.
The monitoring system only provides data and alerts.
3. A BMS is a more complex and integrated system designed to manage all aspects of battery operation.
SANFOU LiFePO4 batteries are all fitted with powerful built-in BMS boards, no matter small capacity (12.8V100Ah, 12.8V50Ah, 12.8V100AhUpGrade) or larger capacity (12.8V200Ah, 12.8V300Ah, 25.6V100Ah) all have BMS protection system, especially Prime Day is coming, it's worth knowing more about the battery model you need, so don't miss out on the event!
BMS is critical in high-drain applications, safety-sensitive environments, and systems where battery life is critical and must be properly configured for specific battery chemistries and capacities.
The Battery Monitoring System can be used in conjunction with a BMS to provide real-time monitoring capabilities to track battery health and performance.
Battery monitoring system can be installed additionally, when you use SANFOU LiFePO4 Battery and install the battery monitoring system, you can clearly know the battery power, charging status, remaining power. Regarding the battery charging and discharging, we suggest not to empty the battery completely, in this case it may trigger the built-in BMS over-discharge function, and you need to activate it by using a charger with 0V activation function (e.g., SANFOU 14.6V20A charger), and then the Battery Monitor system comes into play, so that you can see the battery charging and discharging status through the monitor just as you do with your cell phone's battery level, and you can see the battery's charge status through the monitor. Avoid over-discharge as described above.


Battery Management System(BMS), SANFOU lithium batteries are built-in BMS boards, and the battery as a whole, and the battery monitoring system and battery with half the effort, but you need to install additional. Overall lithium iron phosphate batteries are safe, cost-effective, and have a service life of up to 10 years, making them an ideal replacement for lead-acid batteries. If you have the need, please don't miss the special offer of SANFOU Prime Day, SANFOU gives you an unexpected experience.

Prime Day Event:

SANFOU Prime Day promotion, the activity is strong, wide range of activities, end at 2024. 7.31 welcome you to learn more about the activities!
