Wiring tool and wiring method using the tool

Abstract

The invention discloses a wiring tool and a wiring method using the tool. The wiring board of the wiring tool is provided with a terminal corresponding to the pole of a battery cell in a corresponding battery pack, and the terminal is provided with a line for positioning and collecting. The wiring structure of the location, when in use, the terminals will be distributed on the wiring board according to the arrangement of the poles of the battery cells in the battery pack, so as to simulate the poles of the battery cells through the terminals, and be properly positioned and installed on the terminals The collection line on the wiring structure is equivalent to the collection line installed in the battery pack, so that the group assembly of the battery cells and the wiring process of the collection line can be carried out at the same time or the wiring process of the collection line can be preceded by the formation of the battery cells. Assembling is carried out, which shortens the process length of the entire battery module assembly, completes the wiring of voltage and temperature acquisition lines without relying on lithium battery cells set in groups, and improves the efficiency of the acquisition line wiring in the battery module.

[0002] At present, lithium-ion batteries (referred to as lithium batteries) are mostly used after being grouped into modules. The lithium battery module contains multiple strings of lithium battery cells. The arrangement of telecommunications in the lithium battery module is m rows × n columns, different The number of strings corresponds to different module voltages. The cells corresponding to each string of lithium battery cells use the battery management system (BMS) to monitor the voltage and temperature of the cells. Compared with traditional lead-acid battery modules, the voltage and temperature of the cells are not monitored but only In the design of monitoring the overall voltage, the number of voltage and temperature acquisition lines required by the lithium battery module is more, and the wiring is more complicated

[0003] For lithium battery modules with m rows and n columns, most manufacturers directly connect the voltage and temperature acquisition lines to the battery poles of the lithium battery module (direct wiring method for short). During the assembly process, the lithium battery cells are grouped After the lithium battery module is formed, the voltage and temperature acquisition lines are connected to each battery cell. This method is feasible when dealing with small batches of lithium-ion phones. However, when the lithium-ion battery module When the batch size is too large and the number of acquisition lines is too large, the direct wiring method exposes its problems of low production efficiency, poor batch consistency and unsafety, especially when the voltage and temperature acquisition lines arrive at the assembly workshop before the lithium battery cells, it is necessary to Wait for the lithium battery monomers to arrive and form a group before wiring
