  • Publication number: 20140253046
    Abstract: Generally, a system and a method for controlling a battery to power a load determine a battery temperature and control current flow from the battery based on the battery temperature. If the battery temperature is less than a low temperature, load current is disabled and current is enabled through a resistive load to discharge the battery, at least until the battery temperature is about equal to or greater than the low temperature.

  • Publication number: 20140253045
    Abstract: Generally, a system and a method for controlling a battery to power a load disable battery discharge if a battery voltage is less than a low voltage. Disabling battery discharge inhibits current flow from the battery to the load. Battery discharge is enabled after receipt of a reserve enable signal even if the battery voltage is less than the low voltage.

  • Patent number: 8810058
    Abstract: An interface is disclosed. The interface can include a single node that can be configured to receive a state signal and a serial communication signal. The interface can also include a switch circuit and a switch control circuit, where the switch control circuit is capable of being influenced by the receipt of the state signal or the serial communication signal at the single node and can set the state of the switch circuit based on the receipt of the state signal. Additionally, a switch buffer circuit is coupled between the switch and the switch control circuit, where the switch buffer circuit is configured to prevent the serial communication signal from activating the switch circuit. As such, both the state signal and the serial communication signal can be transmitted over a single node without adversely affecting the operation of pre-existing components.
