Automotive Connectors for BMS

Experience, Reliability and Quality all Importantelements with Connectors for Battery Management Systems

The ideal connector solution offering all the performance required by automotive applications

Background

The development division of ポーカー 無料 オンラインar manufacturer, the subject of this case study, was deciding which connectors to use on the battery management system (BMS) to be fitted to a new electric vehicle model it was developing. In the past, ポーカー 無料 オンラインonnector selection process had been led by the battery manufacturer, but this time it was agreed that ポーカー 無料 オンラインar manufacturer should choose ポーカー 無料 オンラインonnectors in the interests of optimizing performance. However, finding connectors of the right size that could deliver the environmental performance the market demanded was a challenge.

Challenges

Optimization Involved More Than Simply Finding Thinner and More Compact Connectors

The role of a BMS is to monitor the battery’s status to ensure it operates safely and efficiently. Demand for these systems, which are used in both electric vehicles and plug in hybrids, is currently growing. However, to minimize the weight penalty associated with additional systems and maintain interior space and comfort, the manufacturer needed to make the BMS lighter and more compact, and therefore needed to make ポーカー 無料 オンラインonnectors used to connect the various modules thinner and more compact as well. At the same time, it was imperative that the system met stringent environmental requirements for temperature, humidity, and vibration.

The design engineer from the development team who was charged withselecting ポーカー 無料 オンラインonnectors reflects.

“While traditionally the battery manufacturer had been in charge of selecting ポーカー 無料 オンラインonnectors, this time it was agreed that we should handle the selection process to ensure optimum performance. First, we tested a few compact connectors offered by one of our suppliers, but none of them met our requirements. We anticipated a challenging selection process,” says the design engineer.

Because all the pairs of compact connectors the engineertested had low mating force, he was concerned about their vibration resistance and ability to avoid discontinuity. In addition to ensuring that ポーカー 無料 オンラインonnectors were compact and slim-line, it was also important to make sure that they had high mating force and good terminal retention. The supplier’s lack of experience with the automotive industry was a source of concern as well.

“Because the electric vehicle market is still in its infancy, there are still many outstanding technical issues. This means that when developing equipment, not only quality but reliability and track record in the auto industry are very important,” said the engineer.

Despite having been tasked with choosing ポーカー 無料 オンラインonnectors, the engineersimply could not find a set of BMS connectors that satisfied all his client’s requirements. As the number of requirementsincreased, he was at a loss for what solution to use.

Summary of Challenges

There was a need to make the BMS connectors more compact and slim-line.

It was imperative that ポーカー 無料 オンラインonnectors were durable and had ahigh enough mating force and terminal retention to satisfy stringent environmental requirements.

In addition to quality, experience in the automotive sector and reliability were also very important.
