Vehicle-mounted lithium battery management system

Abstract

The invention discloses a vehicle-mounted lithium battery management system, and provides a vehicle-mounted lithium battery management system with a good anti-theft effect. Comprising a lithium battery cell and a shell, the lithium battery cell is arranged in the shell, a connecting plate is movably connected to one side wall of the shell, a connecting rod is connected to the lower portion of the connecting plate, a sliding cavity is formed in the shell, one end of the connecting rod is slidably connected with the sliding cavity, and a guide groove is formed in the side wall of the sliding cavity; a contact piece is elastically and slidably connected into the guide groove, a guide piece is elastically connected to the bottom of the sliding cavity, the guide piece corresponds to the contact piece, the connecting rod corresponds to the guide piece, the contact piece is electrically connected with a warning assembly, and the warning assembly is electrically connected with the lithium battery cell. The lithium battery anti-theft device has the beneficial effects that when the lithium battery is taken out, the circuit of the warning assembly is closed, the buzzer gives out buzzing warning, and the signal emitter sends out a signal, so that the position of the lithium battery is monitored, and the anti-theft effect is improved.

Description

technical field [0001] The invention relates to the related technical field of vehicle-mounted lithium batteries, in particular to a vehicle-mounted lithium battery management system. Background technique [0002] As a widely used means of transportation in urban traffic, electric bicycles are often used for short-distance commuting. Because electric bicycles are more flexible, they are generally parked in open-air parking lots. Since the lithium batteries of electric bicycles are light in weight and are used as the power source of electric bicycles, the price is relatively high, which makes the lithium batteries more risky to be stolen. [0003] China patent authorization announcement number: CN 204124103 U, authorization announcement date: 2015.01.28, discloses an on-board battery anti-theft device, the anti-theft device includes a device installed on the battery to sense the vibration of the battery and generate an electrical signal according to the vibration of the batte...
