How We
Make Better
E-Bike Battery?

Whether you are cruising through the city traffic or soaking in the outdoor air, e-bikes offer a unique riding experience that no other transportation can match. And at the very green beating heart of the e-bike revolution is the silent and efficient lithium-ion battery.

LET'S RIDE

STABLE SUPPLY
OF BATTERY CELLS

Only established battery pack manufacturers with a long-term partnership with cell makers can secure the battery supply for their customers.

Ebike has been around for a long time, but the market really took off during the COVID-19. However, the pandemic has also created a significant shortage of battery cells, which left many e-bike makers with lots of orders to fill but no products to sell. This is when supply chain management becomes a critical issue. Only established battery pack manufacturers with a long-term partnership with cell makers can secure the battery supply for their customers.

Choosing the right cell
is much more than
finding a good price

 

Each cell product has its unique subtle characteristics that are only noticeable through feedback from mass usage and cell-level research. If these characteristics are overlooked and unaccounted for during the battery pack design stage, small flaws will steadily build up and hinder performance later in the e-bike’s life cycle.

UNDERSTANDING OF
SAFETY CERTIFICATIONS

Understanding of and experience with safety certification is the foundation of E-bike battery pack design. Insufficient knowledge of the certification will cause wasted R&D efforts and a less competitive unit price. Experienced pack makers should understand not just the battery certification but also the certification of the end application. Only then the pack maker will be able to design batteries that will pass the safety test in one shot with optimal cost.

IN-DEPTH
MATERIAL KNOWLEDGE

 

A successful e-bike battery structural design requires both understanding of the product application environment and extensive experience in structural design. An Ebike battery engineer must optimize the structural strength, ingress protection, and module layout of the battery as Ebike batteries have very limited space and high requirements for ingress protection.

SYSTEMATIC APPROACH TO
FUNCTIONAL SAFETY

Lithium batteries are dangerous, and as e-bike batteries are getting bigger in capacity, so goes their potency. Designing a safe and dependable battery requires a deep understanding of the end product and a systematic approach to functional safety design, as well as a strong SMT capability to faithfully carry out the design intentions.

In 2020 Kais was among the first China battery maker to make batteries that passed the TUV 13849 safety test, one of the toughest safety tests in the industry. By 2021, Kais has delivered more than 90k units of TUV certified E-Bike batteries worldwide.

IN-PRODUCTION
QUALITY ASSURANCE

An e-bike battery may look simple enough, but the process of assembling thousands of components into a functional battery is more complex than it seems. There are three important aspects that must be taken into consideration when evaluating a battery pack factory, they are environment control, in-production quality control, and incoming material quality control. All three have a significant impact on the battery’s quality.

Testing Lab

Testing is a crucial step in an e-bike battery development and production process. The same amount of care and effort should be invested in designing the tests as in the product. As each e-bike battery is different in the specification and operating environment, a customized testing scheme and comprehensive testing equipment are required to ensure the smooth running of the e-bike battery.

FRIENDLY AND COMPETENT
AFTER-SALE SERVICE

A battery maker’s responsibility shouldn’t end with just the product, the after-sale services are often overlooked, but they are equally important. After-sale service of a battery includes two essential parts: first, competent technical support throughout the battery's useful lifetime, and second, lithium battery second usage or recycling services.
