Wiring tool and wiring method using same

Abstract

The invention discloses a wiring tool and a wiring method using the same. A wiring plate of the wiring tool is provided with binding posts which correspond to pole pillars of battery monomers in a corresponding battery group and are provided with binding structures for positioning collecting wires. When the wiring tool is used, the binding posts are correspondingly arranged on the wiring plate according to the layout of the pole pillars of the battery monomers in the battery group and are used for simulating the pole pillars of the battery monomers, the collecting wires, which are suitably arranged on the binding structures of the binding posts in a positioning manner, are equivalent to collecting wires in the battery group, and the grouped assembly of the battery monomers and the wiring process of the collecting wires are simultaneously performed or the wiring process of the collecting wires is performed before the grouping assembly of the battery monomers, so that a technical process of assembly of a whole battery module is shortened, the wiring of the voltage and temperature collecting wires is finished without depending on grouped lithium battery monomers, and the efficiency of the wiring of the collecting wires in the battery module is improved.

[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
