Boston-Power Inc. has been manufacturing lithium-ion batteries for nearly a decade. The company has developed batteries for the electronics, transportation, utility energy storage and portable power industries, as well as NASA and several other government organizations. Based in Westborough, MA, the company also operates a technology center in Beijing and manufacturing plants in Taiwan and other parts of Asia.

Boston-Power’s battery technology is based on a combination of chemistry formulations, mechanical engineering and electrical designs at the cell and system levels. The cells have a flat, oval-shaped prismatic design that increases dependability.

Because battery manufacturing is a complex process, Boston-Power emphasizes quality control. It also performs extensive electrical and mechanical testing to ensure product safety.
A short circuit in a lithium-ion battery can cause it to ignite or explode,” says Declan Shalvey, chief operating officer of Boston-Power. “There are more than 40 features within the electrical assembly of each battery that need to be checked in order to ensure its absolute safety. And these checks have to be done in real time.”

Although simple electrical tests can find major faults inside the battery, latent faults, such as misaligned elements, can be harder to detect. However, these faults can prove just as dangerous should they develop into actual failures by real-world use. Aware of this, Boston-Power recently began using a customized X-Line HRS inline X-ray system to inspect batteries the company makes in Taiwan. 3DX-RAY Ltd. designed, built and delivered the system in eight weeks.
