  • Battery with an internal microcontroller that draws different currents from the cells internal to the battery based on the temperature of the battery
    Patent number: 9142992
    Abstract: A rechargeable battery with an internal microcontroller, a memory and a temperature sensor. The microcontroller draws a current from the cells internal to the battery used to power device to which the battery is attached. Normally, the microcontroller, is in a first operating mode in which the microcontroller draws a relatively low current. During these periods the temperature sensor generates a signal representative of the temperature of the battery. When the signal from the temperature sensor indicates the battery temperature exceeds a threshold temperature, the microcontroller enters a second operating mode in which the microcontroller draws a relatively high current. While in the second operating mode the microcontroller records in the memory data regarding the fact that the battery temperature exceeded the reference temperature and the amount of time the battery was at a temperature above the reference temperature.

  • BATTERY WITH AN INTERNAL MICROCONTROLLER THAT DRAWS DIFFERENT CURRENTS FROM THE CELLS INTERNAL TO THE BATTERY BASED ON THE TEMPERATURE OF THE BATTERY
    Publication number: 20140055086
    Abstract: A rechargable battery with an internal microcontroller, a memory and a temperature sensor. The microcontroller draws a current from the cells internal to the battery used to power device to which the battery is attached. Normally, the microcontroller, is in a first operating mode in which the microcontroller draws a relatively low current. During these periods the temperature sensor generates a signal representative of the temperature of the battery. When the signal from the temperature sensor indicates the battery temperature exceeds a threshold temperature, the microcontroller enters a second operating mode in which the microcontroller draws a relatively high current. While in the second operating mode the microcontroller records in the memory data regarding the fact that the battery temperature exceeded the reference temperature and the amount of time the battery was at a temperature above the reference temperature.

  • Battery charger capable of performing a full or partial state of health evaluation of the battery based on the history of the battery
    Patent number: 8564242
    Abstract: A rechargable battery with an internal microcontroller. The microcontroller contains a memory in which data regarding the environment to which the battery is exposed are stored. These data are read by a processor integral with the charger used to charge the battery. If these data indicates the battery may have been subjected to a harsh environment, such as being exposed to an excessive temperature, the charger performs a fulle state of health evaluation of the battery.
