  • the tool 12 may be similarly equipped with appropriate logic corresponding to that which was described in the several preceding paragraphs.
  • the tool 12 could be configured to operate in an alternative manner.
  • Non-limiting examples of such alternative operation include: non-variable (i.e., constant) speed operation of the motor; limiting the maximum speed of the motor; operating the motor such that it generates noise when it is activated; delaying the start of the motor after the trigger is pressed; and employing an alternative control methodology to start the motor, such as no soft-start mode or a soft-start mode that is between 10 and 10,000 times longer than the duration of the tool's standard soft-start mode.
  • the adapters 22 and/or battery chargers (not shown) for the second battery pack 20 are provided free of charge to consumers to facilitate the use of batteries from the new battery platform.
  • the second battery pack 20 x can include a controller 1000 that can identify whether the second battery pack 20 x is coupled to a battery pack charger (e.g., the battery pack charger 18 ) having a configuration (e.g., electrical, charging control methodology) that differs from the configuration of its associated battery pack charger (not shown).
  • a battery pack charger e.g., the battery pack charger 18
  • the configuration e.g., electrical, charging control methodology
  • the second battery pack 20 x has a lithium-ion battery chemistry and the battery pack charger 18 is configured to charge a battery pack having a Ni-Cad battery chemistry.
  • the controller 1000 can employ any means for determining whether it is coupled or being coupled to a battery pack charger having a different configuration. For example, proximity switches and/or electronic identification circuits, such as identification resistors, can be employed to identify the particular type of battery pack charger to which the second battery pack 20 x is coupled. In the example provided, the second battery pack 20 x includes an electric terminal that is employed to identify the particular battery pack charger that is used.
  • the controller 1000 can be configured to assume that it has been coupled to its battery pack charger (i.e., to a battery pack charger that associated with the configuration of the second battery pack 20 x ) when it receives a predetermined control signal over the electric terminal from the battery pack charger.
  • the controller can also be configured to assume that it has been coupled to a battery pack charger having a different configuration when no control signal or a different control signal from the battery pack charger. It will be appreciated, however, that various means are known for distinguishing between different battery configurations, including the use of alternate terminals (e.g., alternate power and/or control signal terminals).
  • the controller 1000 can be configured to monitor a state-of-charge of the second battery pack 20 x and when charged to a predetermined level, the controller can control a characteristic of the second battery pack 20 x to mimic the operation of a battery pack having a configuration that is associated with the battery charger 18 .
  • the controller 1000 can control the second battery pack 20 x to mimic a battery pack having a Ni-Cad battery chemistry.
  • the controller 1000 can control the voltage output of the second battery pack 20 x to cause the second battery pack 20 x to provide an output whose voltage varies over time in a manner that employs two inflection points in the voltage-versus-time plot (see, e.g., U.S. Pat. Nos.
  • the controller 1000 can control an output of a control terminal, such as a terminal that is configured to communicate a battery temperature signal to the battery pack charger, so that the output of the control terminal will be interpreted by the battery pack charger 18 as indicating that the second battery pack 20 x is fully charged (see, e.g., U.S. Pat. Nos. 3,935,525; 5,896,024; 6,020,071 and 6,489,752).
  • the controller 1000 can control the voltage of the output of the second battery pack 20 x such that a predetermined minus-delta voltage is found in the voltage-versus-time plot (see, e.g., U.S. Pat. No. 5,896,024. U.S. Pat. No. 6,008,628—the “minus-delta-voltage method”).
  • the controller 1000 can electrically de-couple the second battery pack 20 x from the battery pack charger 18 when the second battery pack 20 x has been charged to the predetermined level.
  • one or more relays can be coupled to the controller 1000 and the positive and/or negative power terminals (not shown) of the second battery pack 20 x .
  • the relay can be normally closed to connect the power terminal(s) to the cells (not specifically shown) of the second battery pack 20 x , but could be opened by the controller 1000 as appropriate (e.g., when the controller 1000 determines that the second battery pack 20 x is charged to the predetermined level).
  • the controller 1000 can employ an alternate charging circuit to control charging when it has determined that the battery pack charger has a different configuration.
  • Such alternate charging circuits can employ circuitry to limit the rate at which power is input to the second battery pack 20 x and/or to inhibit the input of power into the second battery pack 20 x when its state of charge is at or above a predetermined level.
