2results about How to "Reduce charging costs" patented technology

This application relates to the field of battery thermal management technology, and particularly to a method, device, vehicle, storage medium, and product for heating control of a power battery. The method includes: acquiring the current temperature, target state of charge (SOC), and initial SOC of the power battery during charging; determining the target temperature of the power battery based on the initial SOC and target SOC; calculating the temperature difference between the current temperature and the target temperature; and controlling the heating action of the power battery based on the temperature difference. This solves the problems of excessive energy consumption and increased costs in thermal management due to super-fast charging in new energy vehicle charging technology.

The utility model discloses a kind of multifunctional wireless charging equipment, comprising: top seat, with first charging contact surface;Base, inside is equipped with cavity, second charging contact surface is equipped in cavity, and cavity has opening on base, opening is equipped with the cavity door of movable connection, third charging contact surface is equipped on cavity door;The present application can realize three electronic devices charging simultaneously on the same equipment, for example, place mobile phone on top seat, receive wireless earphone in cavity, and unfold cavity door to support smart watch.Three charging areas do not interfere with each other and have high space utilization, effectively solve the defect that traditional equipment charging surface is single, significantly improve use efficiency and reduce the charging cost of multiple equipment users.
