Abstract
Official abstract text for this publication.
A high-voltage battery system is provided that ensures fail safety against a room-temperature short circuit and a high-temperature short circuit in a high-voltage battery in an electric vehicle. The battery system prevents secondary injury due to fire in a vehicle collision or in maintenance while ensuring fail safety against a room-temperature short circuit and a high-temperature short circuit by implementing a type of safety element that ensures fail safety by improving the structure of a cell tap, that is, by partially reducing the cross-sectional area of a current path such that a conductive portion is rapidly melted by substantially high heat when a short circuit occurs in a battery.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery system for a vehicle, comprising: a power relay assembly; a battery management system configured to control the charging and discharging of the battery system; and a plurality of modules connected in series and electrically connected to the power relay assembly, wherein cell taps of a plurality of cell sets within the modules and connecting terminals that connect the cell sets are connected by two welding portions and a melting portion between the welding portions. 2 . The battery system for an electric vehicle of claim 1 , wherein the cell tap of each of the cell sets and the connecting terminal are connected by a first welding portion that connects the cell taps, a second welding portion that connects at least one cell tap extending to the connecting terminal and the connecting terminal, and a melting portion between the first welding portion and the second welding portion. 3 . The battery system for an electric vehicle of claim 2 , wherein the cell tap portion that forms the melting portion between the two welding portions has a conductive cross-sectional area less than a conductive cross-sectional area of other cell tap portions. 4 . The battery system for an electric vehicle of claim 2 , wherein the two welding portions that connect the cell tap and the connecting terminal and the melting portion between the welding portions are applied to the cell set in at least one of the modules including a plurality of cell sets.
