A battery pack includes a battery column and a liquid cooling tube. The battery column includes at least two batteries, and the batteries are arranged in a first direction. The liquid cooling tube is disposed on a surface of the battery column and is configured to dissipate heat for the batteries. The liquid cooling tube includes cooling portions, and the cooling portions are portions having orthographic projections on the battery column. The orthographic projections of the cooling portions on the battery column are cooling regions. The cooling portions extend in a second direction, and the second direction is not parallel to the first direction.

Battery pack

A battery module includes a battery column, a heat insulation pad and a side plate. The battery column includes a plurality of batteries, and the batteries are arranged in a first direction. The heat insulation pad is disposed between two adjacent batteries in the battery column. The side plate is disposed on a side surface of the battery column and extends in the first direction. At least one heat-resistant region is disposed on the side plate and corresponds to a position of the heat insulation pad. The heat-resistant region is any one of a through hole, a blind hole, and a notch or a combination of two or more of the foregoing communicated with each other. At least a portion of an orthographic projection of the heat insulation pad on the side plate is disposed within the heat-resistant region.

Battery module and battery pack

The disclosure relates a battery technology field, and in particular, relates to a battery pack. The battery pack includes a battery array and a liquid cooling tube. The battery array includes at least two batteries, and the batteries are arranged in a first direction. The liquid cooling tube is disposed on a surface of the battery array and is configured to dissipate heat for the batteries. The liquid cooling tube includes cooling portions, and the cooling portions are portions of an orthographic projection of the liquid cooling tube on the battery array. Orthographic projections of the cooling portions on the battery array are cooling regions. In the battery array, at least one of the batteries is located outside a range of the cooling portions.

A power supply system and a control method and control device thereof are provided. The power supply system includes a first power supply device, a heat-dissipation unit, a second power supply device, and a control device. The control device is configured to confirm whether each battery pack in the first power supply device experiences thermal runaway, and control the first power supply device to supply power to the heat-dissipation unit when no battery pack in the first power supply device experiences thermal runaway, so that the heat-dissipation unit dissipates heat from the first power supply device; and control a battery pack not experiencing thermal runaway in the first power supply device and/or the second power supply device to supply power to the heat-dissipation unit when a battery pack in the first power supply device experiences thermal runaway, so that the heat-dissipation unit dissipates heat from the first power supply device.
