In the realm of critical power infrastructure, the batteries are the most crucial components. The batteries can unexpectedly fail due to their nature. Therefore, it’s important to take control of the batteries to ensure business continuity which depends on the backup power. Taking control of the batteries is only possible by using a battery monitoring system. Alpais Battery Monitoring System (BMS) is designed for stationary battery systems.

Alpais BMS monitors individual batteries and strings along with the environmental conditions. Alpais Battery Monitoring System solutions are used for VRLA, VLA, and NiCd batteries. Alpais BMS offers to monitor lead-acid batteries with nominal voltages 2V, 6V, and 12V, plus 1.2V nickel-cadmium batteries.

Alpais can monitor up to 480 batteries on 1 single system. There are 3 main hardware components in the system: Battery Module, String Module, and Control Module.

• 1 Battery Module is for each battery/cell
• 1 String Module is for each string,
• 1 Control Module is for each location, up to 4 strings
• 1 String Module is for up to 120 Battery Modules connectivity

Alpais BMS’s main solutions are called “Standard Solution”, “Battery Voltage Balancing Solution” and “Industrial Battery Monitoring Solution”. In the below, these solutions are presented in detail.

STANDARD BATTERY MONITORING SOLUTIONS FOR ALL KINDS OF APPLICATIONS

Alpais Battery Monitoring System presents a standard solution that covers the main requirements. Standard Solution contains the measurements of the most important parameters of batteries and the strings. Alpais BMS measures and records Internal Resistance, Battery Voltage, and Battery Temperature for individual batteries in real-time. Alpais BMS has a string-based structure and thus monitors strings separately. Alpais BMS measures the overall String Voltage, String Current, and charge/discharge cycles of the batteries. Along with these, Alpais BMS monitors environmental parameters like Temperature and Humidity, which are important for battery health.

 

Standard Solution stands with Alpais Software that allows real-time monitoring, remote access, logs recording, and reporting In PDF and CSV formats in a desired period.

Alpais Battery Monitoring System provides up to 10 years of historical data.

On the Alpais Battery Monitoring System, there are 2 levels of notifications; Warning and Critical. It provides more time for the user to take action. Furthermore, it allows the planning of the budget and time.

Flexibility :The server can be chosen by the user. They can either use a company server or a cloud server. Also, the user can choose the "Control Module with an Embedded Server" option. In this option, Alpais Software is pre-installed into the Control Module and runs on it. Historical data is stored in the Control Module.

ALPAIS BATTERY VOLTAGE BALANCING SOLUTIONS

In the Battery Voltage Balancing Solution along with every feature of the Standard Solution, the balancing/equalization voltage of individual batteries is included. Battery Voltage Balancing aims to maintain the individual battery voltage at the desired charge voltage level for each string. By doing so, the system ensures that all battery voltages in the string are evenly distributed, preventing any bad effects that could result from overcharging or discharging the batteries.

Alpais Battery Voltage Balancing feature helps extend the life of the battery string and increase its capacity, making it an essential tool for efficient battery management. By employing this feature, users can optimize battery performance and ensure the reliable operation of their energy storage, and battery backup systems.

By regulating the voltage of individual batteries; Alpais protects the individual batteries from overcharging and undercharging situations. Since the individual voltages are kept at the desired voltage levels, battery service life is prolonged.

 

INDUSTRIAL BATTERY MONITORING SOLUTIONS

In the industrial areas, high-voltage battery packs are chosen, which can consist of more than 120 batteries in one serial connection (string).

Some of the Datacenter applications the UPS require 480 DCV, and most NiCd applications consist of almost more than 200 cells in one string. This is a pain point for battery monitoring systems in the market. Because, usually a BMS can monitor 32 to 120 batteries on one string. However, due to the hazardous environments of industrial areas, the need for extra protection like a battery monitoring system is essential.

With the brilliant Alpais Software design and hard work of the Alpais R&D team, this problem is solved with the "Sub-String Module". Normally, there are 3 main hardware components in the Alpais system: 1 Battery Module for each battery/cell, 1 String Module for each string, with 1 Control Module that can be connected up to 4 String Modules. The String Module can monitor 120 batteries. And, the Sub-String Module is responsible for lengthening the communication line of Battery Modules (BATMOD) that consist of more than 120 cells in one string. For each additional 120 Battery Modules, 1 Sub-String Module (Sub-STRMOD) is added to the system. In this way, 1 Control Module (CONMOD) is becoming able to monitor up to 480 cells.

Additional Features for Industrial Battery Applications

Due to the hazardous environment by its nature of industrial areas, the hydrogen gas leaks, and the level of electrolytes are assigned to the pain points of the using of Ni-Cd batteries. For this reason, Alpais BMS offers extra protection for a better environment for the batteries thus ensuring reliable power. Along with the constant monitoring of the most important parameters, Alpais BMS can offer a “Halogen-free region” for industrial battery applications.
