Activation device and method for long-term-storage and human intervention-free maintenance-free device battery

Abstract

The invention discloses an activation device and method for a long-term-storage and human intervention-free maintenance-free device battery. The activation device comprises an alternating activating circuit, a safety protection circuit and a single-chip microcomputer; the alternating activating circuit comprises a plurality of groups of activating circuits; each activating circuit group comprisesat least one activating circuit; each activating circuit comprises a switch tube, a bias resistor, a load resistor and a battery to be activated; the grid electrode of the switch tube is connected with the single-chip microcomputer; the bias resistor is connected between the grid electrode of the switch tube and the source electrode; and the drain electrode of the switch tube is connected with theload resistor and the battery to be activated in series. The single-chip microcomputer controls the activating circuits of each group to perform timing conversion so as to realize alternating activation, so that the activation of the to-be-activated batteries is realized. The device is reasonable in design and ingenious in concept, the load capacity of the battery is improved, and on the premisethat the normal work of the single-chip microcomputer is not affected, the problem in activation of the long-term-storage and human intervention-free maintenance-free device battery is solved.

Description

Technical field [0001] The present invention relates to the field of batteries for maintenance-free equipment, and in particular to an activation device and method for long-term storage of batteries for maintenance-free equipment without human intervention. Background technique [0002] Many equipments that are stored once or used in small quantities for a long time are commonly used in the real production and life, national defense and military industries. Many of these equipment are maintenance-free equipment that is left unattended for a long time, such as mines and missiles. Batteries are an indispensable part of these devices. However, long-term storage will passivate the batteries (including but not limited to lithium-thionyl chloride batteries) and produce a protective film between the electrodes. When the current flowing in the battery is relatively high Hours will not affect the work of the battery, which has the advantage of reducing battery leakage and making its stora...

AI Technical Summary

Problems solved by technology

When the battery is passivated, the small milliampere current driven by the battery is enough to support the normal operation of these microcontrollers, but when the device is powered on, this small current is not enough to support the normal operation of the device

On the other hand, in order to make the device work normally, the battery needs to be activated. At this time, the battery voltage drops sharply. If the device is working under low voltage, the sharply reduced battery voltage will affect the work of the single-chip microcomputer, and even damage its control. circuit
