A battery management system of a vehicle includes a first controller configured to control a power-on (IG ON) state and a power-off (IG OFF) state of the plurality of controllers, and a second controller including a real time clock (RTC) and configured to be woken up by directly receiving power from the secondary battery in every preset time period during a preset time calculated based on a count value provided from the RTC when a power-off state is started by the first controller and to monitor states of the main battery and the secondary battery.

A battery load management system and methods of managing a battery load, e.g., in a vehicle, may be directed to a converter that steps down electrical power from an input voltage to a reduced voltage. An electrical bus in electrical communication with the converter may be configured to supply electrical power received from the converter at the reduced voltage to a plurality of electrical loads. A controller may be configured to detect a load shed trigger, and in response to the detection select one or more low-priority loads included in the plurality of electrical loads. The controller may also be configured to reduce electrical power consumption by the one or more low-priority loads.

An energy conversion system, an energy conversion method, and a power system. The energy conversion system may include a bridge arm conversion module, a direct current to direct current (DC/DC) conversion module, a motor, a bus capacitor, and a control module. The control module may be configured to control a bridge arm switch action in the bridge arm conversion module, drive the motor based on an alternating current input voltage supplied by a power supply, form a bus voltage at two ends of the bus capacitor, and control the DC/DC conversion module to charge a traction battery and an auxiliary battery based on the bus voltage. The traction battery and the auxiliary battery can be charged while the motor is driven, thereby achieving higher energy conversion efficiency, low costs, and strong applicability.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.
