A battery includes a first conductive layer having a folded portion, a first edge, and a second edge opposite to the first edge in a first direction of the battery; a first conductive plate located on the first conductive layer; and a first layer comprising an insulating material covering at least one portion of the folded portion, and being distant from the first conductive layer. The first layer partially covers the first edge of the first conductive layer.

Busbar includes joining surface to which a voltage detection line is to be joined, and position restriction part provided on at least a part of a periphery of joining surface and configured to restrict spreading of a corrosion inhibitor that covers joining surface.

An electrical feed-through includes: a feed-through component having an opening; at least one conductor sealed into the opening of the feed-through component in a glass material or a glass ceramic material; and at least one guide component connected to the feed-through component, the at least one guide component including a material that is a plastic.

A circuit board, which includes at least one contact surface for electrical contacting with a contact partner, so that an electric current may be transferred between the circuit board and the contact partner, the circuit board including structures in at least one contact area, which are designed to pierce through contaminant layers and/or oxide layers present on the contact partner, the contact area including the contact surface.

A connecting structure uses a crimp terminal to connect a bus bar and an electrical wire together. The crimp terminal includes a bus bar-connecting section to be crimped to the bus bar, and an electrical wire-connecting section to be crimped to an end of the electrical wire. At least one of the bus bar-connecting section and the electrical wire-connecting section is provided with an oxide film breaking means for breaking an oxide film on the bus bar or a core wire on the end of the electrical wire.

Provided are a secondary battery, a battery module, and a battery pack, which have improved safety. Particularly, since a bulletproof material is disposed on the inside and/or the outside of an exterior part, even when a conductive needle-shaped member penetrates a secondary battery, heating, burning, discharge of evaporated electrolyte, and electrical contact between the needle-shaped member and an electrode can be prevented, thereby improving safety of the secondary battery, the battery module, and the battery pack.

The present subject matter relates to a battery module for use in a vehicle. The battery module may include a housing, a plurality of battery cells disposed within the housing, and solid state pre-charge control circuitry that pre-charges a direct current (DC) bus that may be coupled between the battery module and an electronic component of the vehicle. Furthermore, the solid state pre-charge control circuitry may include solid state electronic components as well as passive electronic components.
