Stationary battery

Stationary batteries come in a wide variety of designs for different applications. They are used for applications where power is necessary only on a stand by emergency basis. Stationary batteries are infrequently discharged. They remain on a continuous float charge so that they can be used on demand. The largest types of stationary batteries are those used for electrical load leveling – they store electrical energy for times of peak power demand and are taken off-line during times of low power demand. Stationary batteries are also used for backup emergency power, telecommunications equipment and uninterruptible power supplies (UPS). They have become commonplace in data centres, commercial buildings, health care facilities …

A stationary battery consists of an appropriate number of cells or monoblocks linked together in a row to achieve a desired on-load voltage. The cells (or the multi-cell batteries) are housed in a freestanding transparent container. The base of the battery container has two pairs of openings against which sets of positive and negative plates are rested. Positive and negative plates are connected together via welded bridges to comprise sets of plates (+) and (-). Multi-polar plates, connected together and segregated by isolating shields (separators) comprise groups of plates which are then placed in the battery container. Each bridge has at least one terminal extending beyond the surface of the top cover. An individual container is closed with a cover, and a multi-cell container (block) is closed with a single lid covering all of the cells. Installed cells are arranged in an insulated manner, ensuring a high level of grounded battery resistance. Cells or multi-cell batteries are connected in series to produce a stationary battery of the desired voltage. This linkage is accomplished via plumbiferous connectors (of the appropriate size) welded to terminals, or via paired connectors.
