The invention provides a battery pack and a vehicle. A cell group is configured in the battery pack, and the cell group comprises a plurality of cells, wherein the cells comprise first cells and second cells, the first cells have a better cold resistance than the second cells, and arrangement positions of the first cells and the second cells depend on the heat dissipation capacity in the battery pack.

Battery pack and vehicle

The disclosure relates to the technical field of traction batteries, and in particular to a battery pack and a vehicle comprising the battery pack. The invention aims at the problem of large heat loss in the existing traction battery in a low-temperature environment. To this end, the battery pack of the disclosure comprises: a frame internally formed with an installation site; a battery module mounted in the installation site and comprising a number of cells; and a side beam connected to an outer side wall of the frame and made of a first thermal insulation material. The above arrangement can reduce the heat transfer coefficient of natural convection between the side wall of the frame and the environment, and reduce the heat flux, thereby reducing the temperature loss of the cells.

A method of processing a workpiece may include forming a first layer on a first side of a base layer. The base layer may be part of a substrate including a plurality of layers. The method may also include forming a second layer on the first layer. A material of the second layer may include metal. The method may also include forming an opening in the second layer, forming an opening in the first layer by etching, and removing the second layer. The method may include dry etching of the first layer.

Systems and methods for etching a substrate

A system and method for monitoring the health of smart battery packs in an electric vehicle and determining when one or more of the smart battery packs needs to be replaced. In addition, the system and method locate optimal smart battery packs to exchange with the one or more battery packs that need to be replaced.

System and method for tracking and storing battery data, and utilizing the data to appropriately match batteries upon swapping

A battery for a vehicle having a fixed battery pack and a replaceable battery pack. The replaceable battery pack has electronic or mechanical locks to semi-temporarily hold the replaceable battery pack in place. The fixed battery pack is held in place via permanent or semi-permanent fasteners such as bolts. A battery controller controls the replaceable battery pack to power motors of the vehicle before controlling the fixed battery pack to power motors of the vehicle.

Split electric vehicle (EV) battery including both a replaceable and fixed portion

The present invention provides a video conference system. The video conference system includes a plurality of terminal equipment and a server. Each of the terminal equipment estimates and transmits real-time bandwidth and conference requirements to the server. A multipoint control unit of the server includes a multipoint controller and a multipoint processor. The multipoint controller determines, according to the real-time bandwidth and the conference requirements, a transfer rule and an allocation scheme corresponding to each of the terminal equipment. The multipoint processor receives the transfer rule and voice data stream or video data stream from the terminal equipment. The server transmits each of the allocation schemes to the corresponding terminal equipment. When any of the terminal equipment transmits new real-time bandwidth or new conference requirements to the server, the multipoint controller determines the transfer rule and the allocation schemes once again.

A split-type aerostatic bearing for supporting a moving table to move frictionlessly on a platform () is disclosed. The split-type aerostatic bearing includes an aerostatic bearing plate (), air floating elements () disposed on a bottom of the aerostatic bearing plate () and a vacuum pre-tightening structure () disposed on the aerostatic bearing plate (). The vacuum pre-tightening structure () is coupled to the aerostatic bearing plate () in a split fashion. Separation of the air floating elements () from the vacuum pre-tightening structure () prevents the aerostatic bearing plate () from bending under a vacuum pre-tightening force, and hence will not affect the air floating area.
