摘要： A method and apparatus for extending the cycle life of a battery by using different charge voltages or different current cut-offs to recharge the battery during the course of the battery's life. The capacity of a battery is gradually depleted as the battery is repeatedly charged and discharged. The rate at which the battery capacity is depleted varies in accordance to the charge voltage, or the current cut-off, used to recharge the battery. For example, higher charge voltages cause the capacity to be more rapidly depleted than lower charge voltages. A battery may be charged using a high charge voltage, e.g., its rated charge voltage, during periods of expected high usage. To extend the battery's cycle life, the battery may be charged using a low charge voltage during periods of expected low usage.

摘要： A system for charging a rechargeable battery supplies a current to the battery to charge the battery. The system determines a temperature associated with the battery and identifies a cutoff parameter based on the determined temperature. The system determines when the supplied current matches a value corresponding to the cutoff parameter and stops further supply of the supplied current to the battery when the supplied current matches the value corresponding to the current cutoff parameter.

摘要： A power supply arrangement for supplying power from a battery (2) to an electric load (3) comprises a controlled switch (4) having a first state in which a connection is provided from the battery (2) to the load (3), and a second state in which the load (3) is disconnected from the battery (2), and a control circuit (5, 8, 9) for controlling the state of the controlled switch (4). The control circuit (5, 8, 9) is arranged to be disconnected from the battery (2) when the controlled switch (4) is in its second state. By disconnecting not only the electrical load, but also the control circuit from the battery, it is ensured that this circuit cannot draw any leakage current from the battery, when the load is switched off. This means that no over-discharge protection is needed in the battery itself.
