  "textContent": "Embodiments of the present application provide a self-heating control circuit and system. The self-heating control circuit includes: a control module configured to obtain a cell temperature of each of two battery packs connected in parallel, and send a trigger signal when the cell temperature is lower than a threshold; a first switch module disposed on a charging and discharging circuit of a first battery pack, where a control terminal of the first switch module is connected to the control module, and is configured to cut off the charging and discharging circuit upon reception of the trigger signal, and the battery packs include the first battery pack; and an excitation module configured to form a path with the two battery packs upon cut-off of the charging and discharging circuit, and generate an excitation current, so that the excitation current flows back and forth between the two battery packs.",
