The invention relates to a power switch (100) for a battery system. The power switch (100) comprises: a first terminal (104); a second terminal (106); a control terminal (102) for receiving a control signal (108); a device (112) for identifying a power switching signal (114) and a communication signal (116) based on the control signal (108); a power section (118) comprising at least one switch (122) for switching an electrical connection between the first terminal (104) and the second terminal (106) based on the power switching signal (114); and a communication section (120) comprising at least one switch (124) for switching the electrical connection between the first terminal (104) and the second terminal (106) based on the communication signal (116).

The utility model discloses an energy storage power supply capable of stacking battery packs, comprising an energy storage power supply host and a battery pack, wherein the bottoms of the front and back sides of the energy storage power supply host are fixedly connected with corresponding rotating shafts. The number of battery packs can be adjusted according to needs when going out for work. In the transportation process, each battery pack can be disassembled through the connecting arm and the auxiliary arm, and the host of the energy storage power supply can also be disassembled separately, and then assembled before use, which is simple and convenient.

A battery pack includes a housing and electrochemical cells disposed in the housing. The housing includes a container and a lid that closes an open end of the container. The container has a base, an outer wall the surrounds the base, and a first and a second inner wall disposed inside the outer wall. The first inner wall extends between, and is fixed to, a first portion and a third portion of the outer wall, and is spaced apart from a second portion and a fourth portion of the outer wall. The second inner wall extends between the first portion and the third portion, and is disposed between the first inner wall and the fourth portion. The second inner wall is movable relative to the outer wall such that spacing of the second inner wall from the first inner wall can be changed.

The invention relates to a battery device (10) for a vehicle, having a main battery system (20) with at least two battery units (BS) and an emergency battery system (30) with at least one battery unit (BS), wherein the main battery system (20) has more battery units (BS) than the emergency battery system (30), wherein the main battery system (20) and the emergency battery system (30) furthermore have the same nominal voltage and are electrically connected in parallel with one another, and the main battery system (20) has a main switch (22) for disconnecting the main battery system (20) and the emergency battery system (30) has an emergency switch (32), separate from the main switch (22), for disconnecting the emergency battery system (30).

A traction battery assembly includes, among other things, a battery cell array having a plurality of individual battery cells. The battery cell array usable with a first busbar module having a first arrangement of busbars. The battery cell array is also usable with a second busbar module having a second arrangement of busbars. When the battery cell array is used with the first busbar module, the battery cell array is partitioned into a first number of groups of battery cells in parallel with each other. When the battery cell array is used with the second busbar module, the battery cell array is partitioned into a different, second number of groups of battery cells in parallel with each other.

A load applicator includes an elastic mechanism, a first member configured to move in accordance with contraction of power storage cells, a second member provided on a side opposite to the first member across the elastic mechanism, and a switching device. The elastic mechanism has a first form in which a first restraint load is applied to the power storage module when the power storage module expands by a first dimension, and a second form in which a second restraint load larger than the first restraint load is applied to the power storage module when the power storage module expands by the first dimension. The switching device performs an operation to switch from the first form to the second form in a case where a restraint load smaller than the first restraint load is applied to the power storage module when the power storage module expands by the first dimension.

Vehicle dashboard built-in battery jumper rack provides a more convenient way to jump start any kind of vehicles' batteries through a connection rack built into the dashboard. The rack is connected internally to the vehicle main battery through electric cables, and includes sockets to be connected externally to the designated removable Li-ion battery pins. This eliminates the need to step out of the vehicle and opening the hood, the whole jump-starting process is completely done while the driver is inside the cabin.
