Batterie-Nachfüllsystem

摘要

A battery refill system is described for filling and maintaining a number of interconnected battery cells (18) at a predetermined level with liquid provided by an external liquid supply. The refill system includes a number of refill valves (20), each associated with a single battery cell (18), and a main supply valve (14) which connects the battery cells (18) to the liquid supply. Tubing (12) is provided for connecting the battery cells in a chain or serial relationship. The tubing (12) is fabricated from a polymeric material which is substantially free of plasticizer bleed such as a thermoplastic elastomer or a fluorocarbon or fluoroelastomer or a fluoropolymer and which has a minimum bend radius of about 2.50 inches (64 mm). The tubing (12) is capable of a service temperature range of between about -20 DEG F and 200 DEG F (-29 DEG C and 93 DEG C), and has a burst pressure of up to about 40 psi (2.76 x 10<5>Pa). Additionally, the tubing (12) has a five-year minimum life, and does not degrade excessively when exposed to sulfuric acid, oil, ozone, or ultraviolet radiation. The tubing (12) has an ultimate elongation of at least 250% at 73 DEG F (23 DEG C), to accommodate various barbed fittings.
