Publication number: 20090202889Abstract: A secondary battery is protected from overcharging and excessive discharge current by a simple circuit. A comparator (CMP1) detects overcharging by comparing a charging voltage. (Vc) of a secondary battery (6) with a reference voltage (Vref1). A transistor (Q1) is turned on to turn the heater (R2) on if overcharging is detected by the comparator (CMP1). A PTC element (SW1) is turned off to cut off a charge current when being heated by the heater to reach a specified operating temperature (Tsw1). On the other hand, when a discharge current from the secondary battery (6) becomes excessive, the PTC element (SW1) self-heats by the discharge current and is turned off to cut off a discharge current upon reaching the operating temperature (Tsw1).Type: ApplicationFiled: May 10, 2006Publication date: August 13, 2009Applicant: PANASONIC CORPORATIONInventor: Iichiro Mori

Patent number: 6911804Abstract: A schedule recording section (4) records a user's schedule. A SOC (state-of-charge) optimization planning section (5) plans the SOC of a rechargeable battery (21) based on the user's schedule. The planned control target SOC is optimized through a comparison between the continuous charging characteristic of the rechargeable battery (21) and the length of an operable period or the amount of electric power to be secured at the time of battery-powered operation. For example, a control target SOC is set at a full charge in the proximity of the period during which a battery-powered operation time is expected to be long. A control target SOC is set lower enough than a full charge in the period during which a connection to an external power supply (A) by the AC adapter (11) is expected to continue for a long time. A power-supply control section (3) controls the charge and discharge of the rechargeable battery (21) according to a plan for the optimization of the SOC.Type: GrantFiled: August 28, 2003Date of Patent: June 28, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Iichiro Mori

Patent number: 6222346Abstract: A control circuit detects the battery voltage E1 of the rechargeable battery, and the terminal voltage E2 across the input/output terminals that are connected to the rechargeable battery through a charge/discharge circuit. When the battery voltage E1 is lower than a charge-prohibiting voltage and higher than a discharge-prohibiting voltage, the control circuit turns on the first and second FETS, which are connected in series to the charge/discharge circuit. When the battery voltage E1 is higher than the charge-prohibiting voltage, the first FET is turned off, and when the battery voltage is higher than the terminal voltage, the first FET is turned on. When the battery voltage E1 is lower than the discharge-prohibiting voltage, the second FET is turned off, and when the battery voltage E1 is higher than the terminal voltage E2, the second FET is turned on.Type: GrantFiled: August 9, 2000Date of Patent: April 24, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Iichiro Mori
