The application discloses a power battery heating method, a power battery heating device and an electric vehicle. The maximum alternating current power that each driving unit can output under different target charge-discharge frequencies and corresponding vibration noise indexes are acquired, and the target charge-discharge frequency corresponding to the maximum sum of the maximum alternating current power of each driving unit when the vibration noise indexes are less than a preset threshold is determined as a frequency reference value. The alternating phase of the bus current of any one of the driving units is acquired, and the acquired alternating phase of the bus current is determined as a phase reference value. Then, the charge-discharge frequencies of the driving units are adjusted according to the frequency reference value, so that the charge-discharge frequencies of the driving units are consistent with the frequency reference value. The alternating phases of the bus currents of the driving units are adjusted according to the phase reference value, so that the alternating phases of the bus currents of the driving units are consistent with the phase reference value. The application aims to improve the heating efficiency of the multi-driving-unit power battery.

This utility model discloses an electrode boiler coupled with a solid thermal storage boiler energy storage system. The water supply pipe is connected to the electrode boiler via valve 5, and the output of the electrode boiler is connected to a first spherical tank via a pipe via valve 6, and then to a second spherical tank via valve 1. The output of the first spherical tank is connected to the user end via a pipe and valve 7, and the output of the second spherical tank is connected to the user end via a pipe and valve 3. The pipes connecting the second spherical tank to the user end pass through the solid thermal storage boiler. The system has high energy storage efficiency, long lifespan, and high safety. The solid thermal storage boiler directly heats the saturated steam stored in the spherical tanks, enabling rapid adaptation to changes in different heating scenarios and demands. It solves the problem that the superheated steam generated by the electrode boiler's superheater cannot be continuously and stably utilized during off-peak hours. The energy storage system can produce both saturated steam and superheated steam.

This utility model relates to the field of garment processing technology, specifically providing a garment processing device aimed at solving the problem of short service life of the electric heating module in existing garment processing equipment. To this end, the garment processing device of this utility model includes a drum and a drying device. The drying device includes a circulating air duct and an electric heating module. The electric heating module includes multiple strip-shaped heating elements spaced apart along a first direction, extending along a second direction perpendicular to the first direction, and the multiple strip-shaped heating elements are arranged in parallel. By setting multiple parallel strip-shaped heating elements, when one strip-shaped heating element fails, the remaining strip-shaped heating elements can continue to work, extending the service life of the electric heating module. Using multiple parallel strip-shaped heating elements increases the overall heating power of the electric heating module, which is beneficial for improving drying efficiency and achieving uniform heating, avoiding problems such as localized overheating or uneven heating.
