ABSTRACT:
FIELD OF THE INVENTION
The present invention is generally related to the maintenance of uninterruptible power supplies (UPS). In particular, the present invention is directed to an improved battery to test system.
BACKGROUND ART
Uninterruptible power supply (UPS) are used in a variety of different environments in which an interruption of power due to the variations or loss of the primary power source is unacceptable. Since reliability is a chief attribute required of such systems, constant maintenance is required. In particular, the batteries that constitute a major portion of a UPS must be constantly checked to make certain that battery banks (which is usually connected in series) have no bad batteries and that the overall load performance of the entire battery tank was at acceptable levels.
Conventionally, the only way to check the battery bank and perform load tests is to physically open up the battery compartment of the UPS unit and place test leads directly on each of the individual batteries located within the main battery compartment. This procedure is very dangerous and has resulted in numerous instances of high voltage arcing with accompanying shock injury to individuals, as well as damage to the equipment.
There are no techniques or systems that avoid these hazards in the conventional art. Accordingly, any user of a UPS would greatly benefit from a test system that would permit safe and fast testing of individual batteries in the UPS.
SUMMARY OF THE INVENTION
Accordingly, it is one object of the present invention to overcome the drawbacks of the conventional technology in the testing of battery banks.
It is another object of the present invention to provide a system for testing voltage and load on batteries in a bank while avoiding high voltage hazards.
It is a further object of the present invention to provide a system for testing batteries in a bank in a UPS where the battery testing can be carried out without entering the battery bank cabinet.
It is an additional object of the present invention to provide a system for measuring individual batteries in a battery bank where only low voltage equipment is required.
It is again another object of the present invention to provide a battery testing system that can be operated under less than ideal conditions with respect to space and light.
It is still a further object of the present invention to provide a battery testing system that can be used with sufficient frequency so that battery bank failures can easily be predicted.
It is yet another object of the present invention to provide a battery testing system that is simple to operate, and has very few parts.
It is again a further object of the present invention to provide a battery testing system that is low in cost.
It is still an additional object of the present invention to provide a battery testing system wherein each battery can be loaded with a relatively high artificial load while observing voltage drops at realistic operating conditions.
It is again another object of the present invention to provide battery testing system in which either a single battery or multiple batteries within a battery bank can be monitored safely.
These and other goals and objects of the present invention are achieved by a battery test system arranged for testing a bank of batteries, where the bank of batteries is constituted by at least two batteries. The batteries are connected in series with main connectors. Also included on each of the batteries is a set of subsidiary connectors located on positive and negative terminals of each of the batteries. The subsidiary connectors are connected from the batteries to a test panel, which has a plurality of pairs of test connectors. As a result, each of the batteries has its own connectors on the test panel.
