Problems solved by technology

[0002] Existing power battery systems are all connected by multiple single cells. During use, one and two cells are often damaged, resulting in the need for maintenance of the entire pack of batteries because of maintenance costs and maintenance costs. Inconvenience to the user, it is necessary to design a battery connection method, which can skip the battery without affecting the use and safety hazards

Abstract

The invention discloses an intelligent battery connector. The intelligent battery connector comprises a needle-shaped connector, an electromagnet surrounding the outer side of the needle-shaped connector, a bidirectional connector, a permanent magnet surrounding the outer side of the bidirectional connector, and a lead wire, wherein the needle-shaped connector is connected to two electrodes of each battery in a battery pack; the bidirectional connector is provided with two connecting points; one side of the bidirectional connector is connected with a rear battery in two adjacent batteries or the other side of the bidirectional connector is connected with a next-stage battery; the electromagnet comprises a current reversal apparatus; the current reversal apparatus is controlled by a battery management system of a battery system; and a current direction is changed through the current reversal apparatus to change an electrode of the electromagnet. According to the intelligent battery connector, bad batteries connected in series can be disconnected according to a detection result of the battery management system to the batteries, so that the whole battery pack is ensured to be in a safe working state.

Description

technical field [0001] The invention belongs to the technical field of integrated application of power battery systems, and in particular relates to an intelligent battery connector. In the technical solution of the present invention, the intelligent battery connector can disconnect the bad batteries connected in series according to the detection result of the battery by the battery management system, so as to ensure that the whole battery pack is in a safe working state. Background technique [0002] Existing power battery systems are all connected by multiple single cells. During use, one and two cells are often damaged, resulting in the need for maintenance of the entire pack of batteries because of maintenance costs and maintenance costs. Inconveniencing the user, it is necessary to design a battery connection method that can skip the battery without affecting the use and safety hazards. Ensure the normal use of the power battery system. Contents of the invention [...
