  "textContent": "A battery pack and a battery system are provided, which relate to the field of fire prevention technologies for energy storage batteries. The battery pack includes a heat insulation panel, a housing, and an energy storage module. The energy storage module is located in the housing, the heat insulation panel is located between the energy storage module and the housing, the heat insulation panel includes a heat insulation layer and an outer packaging layer, and the heat insulation layer includes an elastic heat insulation layer and a fire-resistant layer that are stacked. The outer packaging layer wraps the outside of the heat insulation layer and compresses a thickness of the elastic heat insulation layer, so that the heat insulation panel is compressed to a compressed state, and a ventilation channel is formed between the heat insulation panel in the compressed state and the energy storage module, to meet requirements of ventilation and heat dissipation of the battery pack. The outer packaging layer is configured to release compression of the elastic heat insulation layer when the energy storage module reaches a thermal runaway temperature, so that the elastic heat insulation layer is elastically restored to a free state, and the heat insulation panel in the free state is filled between the housing and the energy storage module, thereby slowing down a speed at which heat passes through a side panel and spreads to the outside of the battery pack along the ventilation channel, and increasing a time for personnel to escape, rescue, and repair.",
