A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.

An electric vehicle includes: an electric motor that generates rotational power by which a driving wheel is driven; a battery case defining a battery accommodating space accommodating at least one battery; connectors that are located in the battery case, accommodated in the battery accommodating space, and electrically connected to respective terminals of the battery; and electric power lines through which electric power of the battery is supplied to the electric motor. The electric power lines include a connection circuit that includes a connection portion where the electric power lines extending from the connectors are connected to each other, the connection portion being located in an adjacent region located adjacent to the connectors.

This application relates to the field of battery technologies, and provides a battery module, a battery pack, and an automobile. The battery module includes two or more battery cells; a module frame, including an end plate and a side plate. The end plate and the side plate form the module frame for fixing the two or more battery cells and a cell management unit is disposed on the end plate and connected to a sampling line of the two or more battery cells. The cell management unit is disposed on the end plate inside the module frame, which facilitates wiring of the sampling line of the battery cells, thus ensuring an effective energy density of the battery module and balancing the wiring of the sampling line of the battery cells and the energy density of the battery module.

Provided is a novel continuous single-step method of manufacturing a multilayer sorbent polymeric membrane having superior productivity, properties and performance. At least one layer of the polymeric membrane comprises sorbent materials and a plurality of interconnecting pores.
