Title: Method for pouring liquid into battery
Inventor: ITO MASATOSHI
IPC: H01M10/28
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a good quality battery which causes no liquid leakage by pouring a particular amount of electrolyte suitable for centrifugal pouring liquid into a battery according to a centrifugal liquid pouring method, first, in pouring a prescribed amount of electrolyte, adding a remaining amount of electrolyte, and conducting decompression operation to a particular pressure range. SOLUTION: In a liquid pouring method, 'electrolyte suitable for centrifugal pouring liquid' means 'the amount of electrolyte to a level at which it does not overflow from the top surfaces of a group of electrodes as surplus liquid without being absorbed in the group of electrodes by the centrifugal pouring liquid'. The final maximum pouring liquid amount which does not degrade the gas absorbing property of the electrode is 80% versus the space volume of a part storing the group of electrodes in a container. Even if pouring amount is increased to the amount, a liquid leak failure rate is very low, and the good gas absorbing property of the electrode is not degraded. A vacuum decompression degree is set to a range of 0.05 to 0.5atm. Liquid leak rate becomes lower to improve productivity of a good quality produce.  If the decompression degree is 0.01 pascal, the electrolyte splashes and adheres to the mouth end of the container. If it is 0.6atm or more, the liquid leak failure rate becomes higher.

Abstract: PURPOSE:To prevent a hydraulic relay from erroneously operating by enabling to switch between a commercial power source and an AC variable speed inverter power source, and controlling to gradually regulate the output frequency of the inverter power source, thereby suppressing the hydraulic change to the minimum. CONSTITUTION:An AC variable speed inverter power source is turned ON when an oil pump is started or stopped to regulate an oil flow. A switching contactor 88T is connected with the inverter power source 4 side when the pump is started to reduce the output frequency, thereby starting the pump. Since, i.e., inverter power source 4 can be obtained in a wide frequency range, an oil pump motor of an induction motor is rotated at the speed proportional to the frequency. Since the hydraulic change due to the oil flow is gradually converged, the output frequency of the power source 4 is raised to match the converting state to gradually increase the oil flow, and the converting state to gradually increase the oil flow, and the power source is eventually switched by the contactor 88T to a commercial power source 1 when approaching substantially to the rated frequency range.
