전기 자전거에 IP67 배터리가 중요한 이유는 무엇인가요?

In today’s rapidly developing global eBike market, battery safety and environmental adaptability have become among the core issues of greatest concern to both OEMs and end-users. Especially in mature markets such as Europe and North America, where rain riding, snow riding, commuting, and outdoor use have become the norm, the stability of batteries in complex environments directly determines the safety limits of a product and its brand reputation.
As a one-stop manufacturer specializing in lithium battery system solutions, We have found that in eBike battery failures and safety incidents, water ingress is the second leading cause of hazard, second only to cell quality. This is why an increasing number of international clients are explicitly requiring battery systems to meet IP67 protection standards during the project initiation phase.

What is IP67?

IP67 consists of two numbers: 6 represents complete dustproof, and 7 represents that it can be submerged in 1 meter of water for 30 minutes without water ingress. For electric bicycle batteries, this means that they remain safe and stable even when riding in heavy rain, on flooded roads, after vehicle washing, and in high humidity environments.

Challenges of Real-World Electric Bicycle Use

Electric bicycles are constantly exposed to rain, snow, road puddles, and humid environments. The battery, especially the lower tube, is particularly vulnerable to water splashed from the tires and impacts from standing water. Compared to a single instance of water ingress, long-term, minor water seepage is more likely to corrode the BMS, connectors, and insulation, ultimately leading to safety hazards.

Why IP67 is crucial for eBike battery safety:

IP67 protection effectively prevents moisture from entering the battery, reducing the risk of short circuits and thermal runaway; it also protects the BMS system for long-term stable operation and significantly extends battery life under the same cell conditions.

IP67 is not simply about applying glue.

A true IP67 battery is a systems engineering project, involving shell structure design, sealing material selection, waterproof interface design, and internal moisture-proof redundancy design. Yizhan Electronics achieves mass-production-grade IP67 protection through a multi-layer sealing structure, waterproof aviation connectors, and partial potting technology.

Yizhan Electronics’ IP67 eBike battery solution

supports 24V / 36V / 48V / 52V systems, covering bottom tube, built-in, and bottle-type structures, supports OEM / ODM customization, and meets international certification requirements such as UN38.3, MSDS, EN, and UL.

Long-term value of IP67 to vehicle brands:

IP67 batteries help reduce after-sales and recall risks, enhance brand premium capabilities, and are easier to pass audits by overseas channels and platforms.

자주 묻는 질문(FAQ)

Q1: What is the difference between IP67 and IP65?

IP65 is splash-proof but not immersion-proof, while IP67 provides short-term immersion protection.

Q2: Can IP67 batteries be submerged in water for extended periods?

No, they are only suitable for accidental water immersion.

Q3: Will IP67 increase costs?

Costs will increase slightly, but far less than the costs associated with after-sales service and brand risks.
In conclusion,

IP67 is not a gimmick, but a fundamental respect for user safety. Yizhan Electronics is committed to providing safe, reliable, and mass-producible battery solutions for global e-bike brands, leveraging its professional manufacturing capabilities.
