Technical Field

[0001] This utility model relates to the field of fixing signal acquisition lines of battery pack control units, and in particular to a fixing structure for signal acquisition lines of battery pack control units. Background Technology

[0002] Golf carts and similar low-speed vehicles typically use lead-acid batteries for power. However, with the development of new energy technologies, newer models are gradually switching to lithium-ion batteries and other renewable energy sources. Older models, still within their service life, are seeing a shift towards lithium-ion batteries in the secondary replacement market. Lithium-ion batteries offer advantages such as light weight, high energy density, powerful performance, and long cycle life. This market context has led to the development of lithium-ion batteries for golf carts.

[0003] However, the signal acquisition (voltage, temperature) circuits of the BMS control unit inside the battery pack are currently mostly fixed by solder or screws. This process is not secure and is easily affected by vehicle vibration in actual applications, which can easily cause problems such as broken wires and poor contact, resulting in overall product failure and reduced product reliability. Utility Model Content
