A vehicular battery control device controls an electric storage amount of a battery as which a lithium-ion battery is employed. The vehicular battery control device includes a control unit that reduces the electric storage amount of the battery until the electric storage amount of the battery assumes a second state, before the lapse of a first time, when the electric storage amount of the battery assumes a first state and it is predicted that a charge current will flow in the first time. The first state is a state where lithium metal is precipitated by charging the battery with a predetermined amount of electric power, and the second state is a state where no lithium metal is precipitated even when the charge current flows through the battery.

An all-terrain vehicle and a method for supply power to an all-terrain vehicle is disclosed. The all-terrain vehicle includes a power supply system including a power source and an energy storage unit. The power source is configured to supply power for a first device and a second device of the all-terrain vehicle. When a voltage of the power source is higher than a voltage of the energy storage unit, the energy storage unit is triggered to store electric energy, and when the power source supplies power to the first device and the second device and a voltage of the power source drops, the energy storage unit is triggered to release stored electric energy to the power source, and the electric energy released by the energy storage unit is supplied to the power source to increase an output voltage of the power source.

The present application discloses an all-terrain vehicle and a method for powering the all-terrain vehicle. The all-terrain vehicle includes: a frame; at least one seat arranged on the frame; a first device; a second device being a micro-control unit, a required electric power of the first device being greater than a required electric power of the second device, and the first device having a lower stability requirement for a power supply voltage than the second device; and a power supply system arranged behind the at least one seat and comprising a first power source and a second power source. The first power source is configured to supply power to a first device. The second power source is configured to supply power to a second device of the all-terrain vehicle.

There are provided a floor panel, a pair of right-and-left floor frames, and a battery unit supporting a battery module and mounted at the floor frames. The battery unit comprises the battery module, a pair of right-and-left side frames mounted at the pair of floor frames, and a pair of front-and-rear module supporting mechanisms which comprises a pair of front-and-rear cross frames respectively extending in a vehicle width direction and interconnecting the pair of side frames and mounting brackets supporting a front end portion and a rear end portion of the battery module. Bending rigidity, in a vertical direction, of the module supporting mechanism comprising the third cross frame and the first mounting bracket is set to be lower than that of the side frame.
