Title: Method and device for monitoring self discharge of secondary battery after completion
Inventor: MERCER MARK J
IPC: H02J7/10
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To monitor the terminal voltage of a secondary battery without losing energy to the extent where it can be recognized by forming a high-impedance node at the low side of a battery and regulating a voltage at the high side of the battery to a value that is lower than the maximum allowable terminal voltage. SOLUTION: Under a monitor mode, a charger controller 210 turns off a field effect transistor(FET) 218 and sets a node 224 to a high-impedance node, and a battery 212 is floated during an entire monitoring period. Then, after a high-impedance node is formed at the low side of the battery 212, the charger controller 210 regulates a voltage at the high side of the battery in a high-side detection input node 222 to a lower, specific value than the maximum allowable terminal voltage of the battery 212, thus measuring the voltage at the low side of the battery. As a result, the only load that can be recognized and applied to the battery 212 is an FET 218, thus extremely limiting the delivery of a battery energy.

Filed: 1992-06-12
Abstract: PURPOSE:To shorten operating cycle time as much as possible by installing a control means which operates a stacker crane according to the appropriate traveling speed pattern of a stacker crane which is preset based on a signal from a loading detection means. CONSTITUTION:A stacker crane 2 recognizes, before traveling, if a load is placed on a fork 8 from the light receiver 11 of a controller 9 kept ON or OFF. When a load exists, the controller 9 reads out a pattern A of two traveling speed patterns stored in a memory device 19. When no load W exists, the controller 9 reads out a pattern B. Based on the read-out pattern, a traveling motor 12 and a lifting motor 13 are driven to make a lifting base 7 travel to a designated position. It is thus possible to acceleration and mximum speed for prevention of load stack collapse at the time of an actual load, and to run the stacker crane at large acceleration and maximum speed because of unnecessary consideration of load stack collapse at the time of no load.
