WIRED VS. WIRELESS: ANOTHER PERSPECTIVE ON LOOKING AT THIS VERSUS

---

What do we expect from a Battery Management System?

Let’s discuss first, what we expect from a battery monitoring system (BMS). Yes, it’s for ensuring the battery backup system's health. Thanks to being a permanent monitoring system every BMS provides reduced cost & time of maintenance and detects the defective battery due to the manufacturing fault.
The obvious reason for using a BMS is because of the necessity to protect the major costs of the investment. However, another important reason is getting the maximum efficiency from the system. Due to the environmental crisis, this reason may be more important than the other. Therefore, the system owner needs to get maximum efficiency from the battery by using the batteries to their last limits.
So, one can say regard to the environmental crisis, the batteries have to be used for just mandatory needs on the system, and to ensure this the BMS has to be energy-efficient.
Another thing needs to be said, to ensure the health of the battery backup system constantly, the BMS has to be providing reliable battery data and getting this in real-time.
In conclusion, the first important point of a BMS is getting reliable battery data, and the second is to be energy-efficient.
Here are some key differences between wireless and wired solutions for battery monitoring systems:

Wireless battery monitoring system solutions:

• More susceptible to interference or signal degradation, which can affect the accuracy and reliability of the monitoring data
• Require more frequent battery replacement for the sensors, as they rely on battery power
• Can be more convenient to install and maintain, as there are no wires to run or connect
• May offer more flexibility in terms of sensor placement, as sensors can be placed anywhere within range of the wireless network

Wired battery monitoring system solutions:

• More reliable, as the wired connection is less susceptible to interference or signal degradation
• More accurate, as the data is transmitted directly from the sensor to the control unit with no intermediate steps
• Can be more difficult to install and maintain, as wires must be run and connected between the sensors and the control unit
• May offer less flexibility in terms of sensor placement, as the sensors must be located near the control unit or a wired connection.

Conclusion

Overall, the choice between a wireless or wired solution for a battery monitoring system will depend on the specific needs and requirements of the application. Factors to consider may include the distance between the sensors and the control unit, the accuracy and reliability of the monitoring data, and the ease of installation and maintenance.

Still, other considerations are the more frequent battery replacement due to the wireless solutions needing more power from the batteries. And, more possible unreliable data getting from the BMS can be allowed to make the wrong/not on-time decisions about the system.

In the end, wired BMS solutions are more reliable and energy-efficient than wireless BMS solutions. The concerns about the wired solutions that they are may be more complex installation and configuration processes.

How does the Alpais Battery Monitoring System resolve the concerns about the wired solutions?
The main pain about the installation of a wired BMS is the time of configuration and the installation. Because most of the BMSes in the market require manual addressing for modules/sensors which requires much more time to commission the system. Most products in the market require pushing a button on battery modules/sensors for a few seconds for each battery module/sensor to obtain its ID addresses. Furthermore, most of the time the systems include hundreds or even thousands of batteries. Which needs a lot of time and man-work, and obviously it costs a lot.

Alpais BMS presents its “AUTOMATICALLY ADDRESSING” feature for Battery Modules just there. There is no need to touch the modules after connecting the cables.



As you can see below figures; with the Installation Mode, the modules obtain their ID addresses automatically.



The final conclusion is with an “automatically addressing” feature a wired solution can be a cure for a reliable, energy-efficient, and easy-to-maintain battery system.

Alpais BMS offers a Control Module with an Embedded Server as another solution for decreasing time and cost and providing an easy installation and commissioning process.
