Dynasty NDSL Cellwatch - Batteries

Cellwatch components

Cellwatch consists of 3 main building blocks, which are:

Battery Monitoring Unit (BMU). An IBM commercial grade notebook computer with its own battery back up, running Windows98/ME as well as Cellwatch proprietary battery monitoring software. This is mounted behind glass, in a secure locked steel cabinet to avoid tampering.

Control Unit (CU). Interface from the computer's RS-485 serial data bus to Cellwatch's own proprietary fiber optic network. Also provides up to 4 current sensor and 4 temperature sensor inputs as well as 4 volts free alarm outputs.

Data Collection Module (DCM). A small electronic measurement instrument capable of measuring up to 12 volts DC nominal and 39 milli-ohm internal resistance on each of 4 cell (jar or mono-bloc) inputs. Hence one DCM is required for every set of 4, 2 volt to 12 volt (nominal) measurement point.

Other components of the Cellwatch system include 1000 amp current sensing 'clamps', solid state temperature probes and Fiber Optic Network Cable .

Cellwatch software is included in a system and is written as Microsoft Windows application to be intuitive and informative. It has a number of standard graphical reports that provide optimal battery data. The intuitive entry screen shows instantly if something is wrong.

The system is CE listed in Europe, Underwriter's Laboratories (UL) listed in the United States, and CSA listed in Canada.

Features and Benefits
• Fully automatic cell monitoring system designed to run 24 hours a day, 365 days a year.
• Cellwatch is supported by a 2U high, rack mount server running Windows XP. Immediately the computer is started the CELLWATCH measurement and analysis software runs and starts to scan your batteries. Even if your monitoring system is installed onto a network it can perform a fully automatic boot and scan. From then on, with no other applications running on the system, your batteries are being watched by this dedicated machine. Current and temperatures are being measured thousands of times a day. Voltages are measured up to 24 times a day on each cell, that can mean up to 3/4 of a million measurements. Ohmic value is measured every 12 or 24 hours, ensuring no event just slips between the testing cracks. No other system can measure your batteries' important parameters, daily.
• Monitors cell, string and battery voltage, cell ohmic value, current and temperature.
• Data collected from continuous cell monitoring is stored on the system hard drive and can be accessed from remote computers. In addition it is reviewable in graphical format on the built in computer over a network or the Internet, any time during the day. At the end of the day, all the data for the day is averaged and stored in a file on the hard drive for local or remote reviewing as a historical trend so that you can see what has happened and predict what is likely to happen in future.
• Tests are performed multiple times per day for accurate and immediate warning.
• Whether we like it or not, lead acid batteries can go from good to useless in under 7 days. Automatic, electronic battery monitoring is used to fill the gap between 3 monthly technician visits or monthly traditional battery monitoring scans. Cellwatch scans all battery parameters more than once per day to ensure nothing slips between the cracks. If things aren't looking right on the battery, (such as a temperature alarm or a discharge is taking place) we don't cancel the scan and hope to catch up later. We will alert the user, and will always get back to the scan when the crisis is over.
• Tracks discharge events automatically for instant record of cell failure or weakness.
• The best way to test a battery is to use it. But we don't expect you to be in your battery room the day the power fails in your data center. That's why Cellwatch does the job for you. Cellwatch will automatically measure the performance of every cell on every battery in the discharge and will determine automatically the best and worse performing cells. You can later compare this information with other cells on the system and make your own maintenance plans accordingly.
• Solid state, no moving parts, low voltage. All add up to a high reliability system.
• No high DC voltage systems, no long wiring looms, no switching relays (except for 4 remote alarm switches that we added so you can interface our electronics easier).
