Patent number: 5315253Abstract: Method and apparatus for measuring the voltage and state of charge of a secondary battery. The voltage and state of charge values are taken by a circuit every four (4) seconds by reading voltage, waiting two (2) seconds, reading current, waiting two (2) seconds, and repeating the voltage readings and the current readings. The circuit includes a 4-bit microprocessor, CMOS analog switches, and two operational amplifiers. The voltage and current readings are taken from dual-sloped converters, and the values determined by software algorithms in the microprocessor.Type: GrantFiled: August 28, 1992Date of Patent: May 24, 1994Assignee: Alexander Manufacturing CompanyInventors: Richard B.

Patent number: 5229566Abstract: Process for spot-welding a flexible welding board to at least one and preferably a battery cells to form a battery pack, such as a NiCad battery pack. The flexible welding board is a nickel alloy material, laminated to a polyester film by a co-extruded adhesive. The spot-welding is accomplished by one spot-welder, and preferably two spot-welders, which spot-weld in alternating time intervals so as to assure electrical and electromechanical contact with each end of the battery cells by the nickel alloy material. The spot-welding is by DC current and voltage. The electrodes are small enough to form a configuration between the flexible circuit and the end of the battery cell. Three spot-welding electrodes would assume a triangular configuration. Four spot-welding electrodes would form a rectangular configuration.Type: GrantFiled: November 29, 1990Date of Patent: July 20, 1993Assignee: Alexander Manufacturing CompanyInventor: Richard B.

Patent number: 5223690Abstract: Process for spot-welding a flexible bare backed welding board to at least one and preferably a plurality battery cells to form a battery pack, such as a NiCad battery pack. The flexible bare backed welding board is a nickel or other metal alloy material, laminated to a polyester film by a co-extruded or otherwise applied adhesive. The spot-welding is accomplished by one spot-welder, and preferably two spot-welders, which spot-weld in alternating time intervals so as to assure electrical and electromechanical contact with each end of the battery cells by the nickel alloy material. The spot-welding is by DC current and voltage or alternatively can be AC welded. The electrodes are small enough to form a configuration between the flexible circuit and the end of the battery cell. Three spot-welding electrodes would assume a triangular configuration. Four spot-welding electrodes would form a rectangular configuration.Type: GrantFiled: May 22, 1992Date of Patent: June 29, 1993Assignee: Alexander Manufacturing CompanyInventors: Richard B.

Patent number: 5196779Abstract: A battery maintenance system for charging, analyzing, discharging and conditioning of a NiCad battery. The system displays voltage and capacity to determine whether or not a NiCad battery has enough capacity to power equipment for an optimal time period. The system charges the battery using a negative delta voltage method of detecting full charge, while also displaying instantaneous battery voltage. The system also analyzes the battery in a charge, discharge and recharge mode of operation, and during the charge mode the instantaneous voltage is displayed. The discharge mode discharges the battery to one volt per cell while displaying voltage and accumulative capacity alternately. The system also conditions batteries by cycling a battery through three cycles of charging, discharging and a subsequent recharge cycle.Type: GrantFiled: November 16, 1989Date of Patent: March 23, 1993Assignee: Alexander Manufacturing CompanyInventors: Richard B.
