Apparatus and method for monitoring batteries and storing data based on battery status

A method for monitoring a power feed from a plurality of batteries in a vehicle, the method comprising:

• receiving, at a first circuit portion, a first signal indicative of a first power feed for a first battery and a second signal indicative of a second power feed for a second battery;
• transmitting an interrupt signal indicative of each of the first power feed and the second power feed being equal to or below a minimum voltage threshold to a microprocessor;
• entering into an emergency operation mode to store data corresponding to at least one vehicle operation for a predetermined amount of time in response to receiving the interrupt signal at an interrupt input of a microprocessor;
• processing, at the microprocessor, a first digital version of the first signal that is indicative of the first power feed to generate a first digital signal;
• receiving, at the microprocessor, another signal indicative of the first power feed for the first battery;
• processing, at the microprocessor, a second digital version of the another signal that is indicative of the first power feed to generate a second digital signal;
• comparing the first digital signal to the second digital signal;
• and
• transmitting an alert indicating that a controller is malfunctioning in the event the first digital signal indicates that the first power feed for the first battery is different than the first power feed for the first battery as indicated by the second digital signal.

An apparatus for monitoring a power feed from a plurality of batteries in a vehicle, the apparatus comprising:

• a controller including:
• a first circuit portion configured to:
• receive a first signal indicative of a first power feed for a first battery and a second signal indicative of a second power feed for a second battery;
• and
• transmit an interrupt signal indicative of each of the first power feed and the second power feed being equal to or below a minimum voltage threshold;
• and
• a microprocessor including an interrupt input and being configured to store data corresponding to at least one vehicle operation for a predetermined amount of time prior to the microprocessor being disabled in response to receiving the interrupt signal at the interrupt input, wherein the microprocessor is further configured to:
• process a first digital version of the first signal that is indicative of the first power feed to generate a first digital signal;
• receive another signal indicative of the first power feed for the first battery;
• process a second digital version of the another signal that is indicative of the first power feed to generate a second digital signal;
• compare the first digital signal to the second digital signal;
• and
• transmit an alert indicative of a malfunction in the event the first digital signal indicates that the first power feed for the first battery is different than the first power feed for the first battery as indicated by the second digital signal.
