If you’re operating mission critical systems and relying on the protection of an UPS and battery bank, then it has to make sense to
have battery monitoring and management.
It’s about peace of mind – knowing that the batteries are healthy and being constantly monitored. Knowing that everything has been done to protect your enterprise from the consequences of a power failure.
The Sosaley BMS takes a modular approach to battery monitoring. This means that by selecting from a range of options, the system can be tailored to meet your specific requirements. VRLA or wet cells, lead acid or Ni-Cd – we have a solution for every battery.
We are also working on a version 2.0 of our BMS with wireless battery connectivity and cloud based control, ready for release in Aug’2016.
The BMS architecture consists of multiple modules each of which can handle 32 individual batteries. The modules are connected to a master controller that stores and processes the incoming data. Theoretically, each of these modules can become a sub-master when you connect another module to it's 32nd point. Cascaded in such a manner, you can connect and manage infinite number of batteries.
Our proprietary architecture includes multiple redundancies to ensure safety and reliability at all times. The sensors, modules and master controller are designed to be isolated from surges and power spikes. The master controller gets it's own power from your UPS or Inverter and thus is never down. The master controller is also capable of both wired and wireless communication protocols, as per your needs.
Sosaley provides a secure and cost-effective cloud framework for data collection and communication between the Battery Management module and user. Your data is secured and stored in a biometrically sealed facility with redundancies built into the system for safeguarding against data loss.
Our continuous data sampling, reporting and battery management capability delivers all the necessary information at your fingertips, as well as to UPS/battery manufacturers/dealers for preventative maintenance. The cloud can also send SMS/email alerts directly to service technicians to inform them about the status of the batteries.
Batteries are the critical part of any UPS. They store energy and supply the stored energy when needed. They have a limited life that can be extended with proper maintenance. In most installations, particularly in small set-ups, once the UPS is installed, we tend to close the door and forget about it. Like all devices, UPS also needs regular inspection and maintenance.
In order to help you understand what constitutes a battery, we list below some of the factors that affect battery life.
Individual Battery Voltage
Incorrect charge voltages may result in loss of capacity, accelerated grid corrosion, excessive gassing and premature end of life. Voltage also identifies catastrophic failures, such as short circuit cells, and gives true visibility of performance under discharge.
A battery’s life-span is normally specified at 20 or 25 degrees centigrade. Temperatures outside of the specified range can significantly affect the battery’s corrosion rate, and therefore the life of the battery. An 8-10 deg temperature increase can decrease battery life by 50%.
String current monitoring measures the energy delivered or accepted by each battery string. A UPS will only measure total current and cannot detect imbalances between strings. An imbalance highlights potential problems within a battery string. String current measurement also allows detection of incorrect battery charging and any significant earth leakage faults. Total string voltage tracking the string voltage confirms the charger is on and performing correctly.
Individual Battery Impedance (ohmic value)
The impedance of a battery will increase with age. High impedance results in a battery that cannot supply the required current – its key task. High impedance also highlights poor connections and open circuit before failure. Batteries can fail in a very short period of time (less that a week) so measuring impedance daily allows you to detect faulty batteries without the need to discharge them. By analysing trending impedance you can accurately determine the end-of- life of a battery.
Measuring the temperature of each battery highlights localised environmental problems through poor HVAC. It can also highlight poor connections and excessive charger ripple. Temperature is a critical parameter for NiCad batteries. Most importantly, battery temperature measurements allow the early detection of thermal runaway.
Sosaley's BMS consists of two modules. The Master Controller collects battery data, executes calculations where needed, and manages all external communication. The master controller board is 50x75x40mm in size and has onboard RAM and processors for advanced processing and communication.
The individual battery modules sit on top each battery and sends data to the master controller 24/7. They are capable of wired and wireless communication with the master controller. Individual battery modules are just 25x50x15mm each.
Sosaley has been leading from the front in terms of embedded design and development. We have spent nearly 50 man years of effort in designing and developing the BMS. All our knowledge and expertise in embedded design, Android development, and communication protocols have been used here. In addition, our BMS is far ahead of any similar product in the market because of the following reasons:
32 bit Microcontroller
Our microcontroller is powerful enough to handle multiple operations such as wireless communication,
remote operations, data mining operations and any new features via future software upgrades.
Experience and Industry Feedback
Our product development has been guided by a 40 yr industry veteran to ensure that we exceed the
industry standards in all aspects of the development process.
Our BMS specifications are tailor made to fit the industry requirements.
Proprietary Cloud Framework
Our solution includes integration with the cloud for remote access from anywhere across the globe. We rely on our own custom developed back-end servers and framework instead of third-party vendors thereby increasing the security of your data.
Wireless Communication Options
Our controller can communicate via a variety of protocols such as serial port, Wi-Fi, GSM, RF etc.
Ease of Installation
The individual battery modules are simple plug and play devices that can be installed live. Easy to install and easy to replace. Detailed instruction manual available.
Remote Control of Your Batteries
Sosaley’s BMS is the only solution with the feature to cut-off your batteries in case of emergency/vacation feature. This feature also provides protection against spikes and short-circuits.
Integration with Manufacturers and Distributors
Our cloud/master-controller can directly provide feedback to UPS manufacturers and distributors, enabling them to perform remote services and preventative maintenance.
We can tag each customer with a unique ID so manufacturer or distributor can analyze and use the performance data to optimize their service and future offerings.
Advanced Customer Support
We provide a comprehensive support service along with our BMS solution and offer free replacements for up to 1 year.
