Abstract: A battery formation apparatus includes a DC-DC conversion module, an additional power supply, and a control circuit. Low-voltage and high-voltage terminals of the DC-DC conversion module are electrically connected to the control circuit and a DC bus, respectively. The DC-DC conversion module is configured to, when a battery unit discharges into the battery formation apparatus, convert a first voltage input into a second voltage greater than the first voltage, and output the second voltage. The additional power supply is electrically connected to the control circuit, and configured to output an additional voltage. The control circuit is electrically connected to the battery unit, the low-voltage terminal of the DC-DC conversion module, and the additional power supply. The control circuit is configured to serially connect the low-voltage terminal of the DC-DC conversion module, the battery unit, and the additional power supply when the battery unit discharges into the battery formation apparatus.

Abstract: This application discloses a method and an apparatus for picking up a virtual item in a virtual environment, a terminal, and a computer-readable storage medium, which belong to the field of human-computer interaction. The method can include displaying a user interface, and obtaining, according to a first instruction triggered by an interaction operation on the user interface, an operation trajectory formed by the interaction operation on the user interface. The method can further include obtaining, in a case that the operation trajectory forms an enclosed region, at least two target virtual items located in the enclosed region in the virtual environment, aggregating the target virtual items in a designated location in the virtual environment, and controlling, in a case that the virtual object moves to the designated location, the virtual object to pick up the target virtual items.
