Control system for battery health assessment, charging, and fault mitigation

A low voltage system of a vehicle, the system comprising:

• a battery;
• one of a generator and an accessory power module (APM);
• one or more low voltage load;
• and
• a smart energy center comprising:
• a first electronic fuse configured to selectively connect the smart energy center to the battery;
• a second electronic fuse configured to selectively connect the smart energy center to the one of the generator and the APM;
• a third electronic fuse configured to selectively connect the smart energy center to the one or more low voltage load;
• a plurality of sensors;
• and
• a controller configured to selectively activate and deactivate the first electronic fuse, the second electronic fuse, and the third electronic fuse based at least in part on data received from the plurality of sensors,
• wherein the smart energy center is configured to estimate a state-of-health (SOH) of the battery by:
• disconnecting, via the second electronic fuse, the one of the generator and the APM, from the smart energy center;
• removing a surface charge from the battery by selectively connecting both the battery and the one or more low voltage load to the smart energy center, via the first electronic fuse and third electronic fuse, respectively;
• determining a discharge resistance of the battery;
• and
• calculating the SOH of the battery at least based in part on the discharge resistance.

• wherein the smart energy center is configured to obtain a state-of-charge (SOC) of the battery and based on a determination that the SOC is below a threshold percentage charge the battery by:
• connecting, via the second electronic fuse, the one of the generator and the APM, to the smart energy center;
• and
• providing a charging current having a set value to the battery by selectively activating and deactivating the first electronic fuse,
• wherein the set value is determined based at least in part on the SOC of the battery and wherein the smart energy center controls the set value by controlling a duty cycle of the first electronic fuse.
