Parallel lithium battery pack

Abstract

The invention provides a parallel lithium battery pack. The parallel lithium battery pack comprises a battery pack shell, a bottom plate, isolation plates, a mounting base, single lithium batteries and a battery pack cover, wherein the battery pack shell is cuboid-shaped; the bottom plate is fixed on the lower part of the battery pack shell; the multiple uniformly-distributed isolation plates are fixed on the upper surface of the bottom plate; the mounting base is arranged on the lower part of the space which is formed by the isolation plates through division; the single lithium batteries are fixed on the upper part of the mounting base; the thickness of the single lithium batteries is matched with the distance between the isolation plates; the battery pack cover covers the upper part of the battery pack shell; and a locking apparatus is arranged between the battery pack shell and the battery pack cover for fixation. The parallel lithium battery pack is simple in structure, convenient to use, and capable of effectively positioning the multiple single lithium batteries due to the mounting base, so as to prevent shaking and to ensure use safety; and by virtue of connecting plates, current output amount can be elastically adjusted according to requirement of a user, cost can be effectively lowered, and the use range of the lithium battery is expanded, so that the parallel lithium battery pack has high market prospect.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a parallel lithium battery pack. Background technique [0002] The currently used lithium battery cell is mainly composed of a casing, an electrolyte solution and a battery cell placed in the casing. The top of the lithium battery cell is provided with a positive electrode conductive electrode post and a negative electrode conductive electrode post. The tops of the positive electrode pole and the negative pole pole are respectively provided with external threads, so that after screwing a nut respectively, different conductive terminals are respectively fixed to output power. [0003] However, the above-mentioned lithium battery cells can only output a fixed voltage and current, but for power machinery such as automobiles that require high current, it is necessary to connect multiple lithium battery cells in parallel and connect them with multiple sets of connecting wires.

Problems solved by technology

[0003] However, the above-mentioned lithium battery cells can only output a fixed voltage and current, but for power machinery such as automobiles that require high current, it is necessary to connect multiple lithium battery cells in parallel and connect them with multiple sets of connecting wires. Unplanned arrangement and connection methods will not only increase the overall space occupied, but also may melt the protective layer of the connecting wire when the positive and negative conductive electrode posts heat up during the charging and discharging process of lithium battery cells. risk of short circuit

Furthermore, due to the improper arrangement of multiple lithium battery cells, when any lithium battery cell explodes or swells, it may affect and cause damage to other lithium battery cells.
