Problems solved by technology

[0006] However, in the battery as described above, the sensing wires provided on the battery cells are exposed to the outside of the battery cell, so they are easily exposed to moisture, and there is a possibility that a short circuit occurs between the battery cells and the sensing wires. Phenomenon, and there is a disadvantage that the wire may be disconnected during the installation work
[0007] In particular, considering that such a battery is provided with sensing lines for each of the battery cells connected in a stacked state, there is a risk of fire due to a short circuit.
[0008] In addition, this type of battery also has the disadvantage of inducing battery management system failures due to the noise generated by the exposed sensing wires.

Abstract

The invention relates to a battery of an electric automobile. The battery comprises a plurality of battery units, an external contour frame and an induction signal device, wherein the battery units are arranged in the external contour frame in a stacking way; the induction signal device is arranged on the external contour frame in a pattern form and is used for providing a metal material communication line of a film for the external contour frame; the two sides of the induction signal device are respectively connected with poles of the battery units and a terminal. According to the battery provided by the invention, induction signals can be smoothly transmitted by using the induction signal device.

Description

technical field [0001] The present invention relates to batteries for electric vehicles, and more specifically relates to batteries for electric vehicles that provide information such as voltage or temperature of battery cells that supply power to a battery management system (BMS: Battery Management System) through an inductive signal device. Background technique [0002] Generally speaking, an electric vehicle or a hybrid vehicle is operated by using electricity charged in a battery, and it has gradually become popular as it is classified as an environmentally friendly vehicle due to high oil prices and environmental improvement. trend. [0003] Such an electric vehicle or a hybrid vehicle requires high electric power, and a battery installed therefor supplies power to the vehicle while repeatedly charging or discharging by connecting a plurality of battery cells in series or in parallel. [0004] Recently, in order to more effectively manage the battery installed in the v...
