Abstract

The invention discloses a conveniently-dismounted high-capacity rare-earth lithium battery module used in a high-low-temperature range. The conveniently-dismounted high-capacity rare-earth lithium battery module is characterized in that a rare-earth lithium battery cell of the conveniently-dismounted high-capacity rare-earth lithium battery module used in a high-low-temperature range is installed in a support of a detachable spliced structure, and the support is divided into an upper layer and a lower layer; a conducting wire connecting piece is welded to a rare-earth lithium cell part and fixed to the support part by virtue of a bolt. By adopting the conveniently-dismounted high-capacity rare-earth lithium battery module, the single rare-earth lithium battery cell is replaced under the situation that the single rare-earth lithium battery cell is damaged, and the battery can be used normally. The battery does not need to be rejected integrally, and the unnecessary waste can be avoided; the single rare-earth lithium battery cell part with a fault can be successfully dismounted, a good single rare-earth lithium battery can be replaced, finally the rest part can be used continuously, and thus simplicity and economical efficiency in replacement can be realized. The conveniently-dismounted high-capacity rare-earth lithium battery module can be used in an environment of -43 to 65 DEG C and has the advantages of wide high-low-temperature application range, high capacity, small internal resistance, long service life, high efficiency, controllability of current output, and the like.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a large-capacity rare-earth lithium battery module that can be disassembled for use within the range of high and low temperatures. Background technique [0002] The development of battery technology is becoming more and more mature, especially as the traditional lead-acid battery is always on the basis of continuous optimization and improvement, and its various performances have reached the best level; in recent years, with the application of new battery technologies, lithium battery technology has developed rapidly , the market is flooded with lithium batteries of various specifications and different uses, and there are good and bad; no matter what kind of battery, it mainly revolves around five parameters (battery capacity, nominal voltage, internal resistance, discharge termination voltage and charge termination voltage) Developed as a goal, so the rules that batteri...
