Description:FIELD
The present disclosure relates to fixtures used in the Battery Management System.
DEFINITIONS
As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicates otherwise.
Takt rules: The term “Takt rules” is a set of instructions used to estimate and establish the appropriate takt time, ensuring efficient alignment of production with customer demand.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
The current Battery Management System (BMS) fixture is facing significant challenges. This is mainly due to a longer assembly time and a labour-intensive process. Adding rubber to the sides of the BMS fixture makes the assembly more complex. Because the assembly is done manually, compressing the rubber precisely is necessary, which leads to inefficiencies and more differences between parts. This impacts the overall production efficiency and requires a large workforce for the assembly line. Additionally, the soft rubber causes problems with friction, making the assembly difficult and prone to mistakes.
The current challenges associated with BMS assembly demand an innovative solution. The existing assembly process is hindered by issues such as increased friction between plastic components, reliance on rubber-based solutions, and a cumbersome manual assembly method. These problems contribute to prolonged takt time and decreased overall production efficiency. The need for a solution becomes evident in addressing the complexities of the current assembly process and finding a way to streamline it.
Therefore, there is felt a need for a BMS holder fixture that alleviates the aforementioned drawbacks.

Revamping the current Battery Management System (BMS) fixture is imperative to overcome the substantial challenges it currently faces. The prolonged assembly time and labor-intensive process, exacerbated by the complexity introduced by rubber components, underline the necessity for innovation. The manual assembly, especially the precise compression of rubber, leads to inefficiencies and variations between parts, impacting overall production efficiency. The reliance on rubber and the friction issues with plastic components further compound these challenges. To address these complexities, there is a clear need for an innovative solution that streamlines the assembly process, reduces takt time, and enhances overall production efficiency.
The present disclosure introduces a solution to the challenges associated with BMS assembly. The key innovation lies in the configuration of a fixture tailored for holding and assembling the BMS with a pre-stressed interference fit. By doing so, the fixture significantly reduces friction between plastic components, mitigates the need for rubber-based solutions, and streamlines the assembly process. The fixture's adaptability to variations in BMS dimensions ensures a consistent and reliable assembly, marking a substantial advancement in the field of BMS manufacturing.
A preferred embodiment of a fixture assembly 1000 for a battery management system of the present disclosure will now be described with reference to Figure 1 through Figure 5. The preferred embodiment does not limit the scope and ambit of the present disclosure.
