Stationary battery plants are an essential component of most uninterruptible critical power systems. Of particular importance are battery plant runtime and battery plant safety under full load operating conditions. This is such an important matter that some critical infrastructure industries, such as electric generating facilities, are now under federal regulation requiring them to monitor and report on the integrity of their backup battery systems. A key element in both run time and safety is the integrity of the electrical connections that interconnect the individual jars in a string, as well as the inter-tier connections between blocks of jars. Poor or degrading connections can cause a range of performance and safety problems, including excessive voltage loss and dangerous heating conditions. Fearing the wrath of federal regulators, technical managers are consequently required to develop onerous compliance plans, with the hope that their plans hold up to scrutiny.
