AIS certifies Britishvolt’s first 21700 cylindrical cell

Our efficient testing provided a quick and thorough turnaround for the battery pioneer.


Britishvolt selected AIS as the professional testing facility for UN38.3 certification of their 21700-cell due to our ability to complete the process in an efficient time.

This is a significant milestone for the battery cell developer. It means they can now ship the development cells to potential clients – including blue-chip OEMs (original equipment manufacturers).

The AIS battery abuse testing team often collected the cells for the scope of work in person. This was to ensure urgent deadlines were met and we are pleased to say that the testing provided a positive outcome for Britishvolt as the cells passed key safety measures.

Andrew Bennion, Managing Director, AIS:

“AIS is delighted to have been selected by Britishvolt and proud that our expertise in certification and homologation to various international standards has enabled us to support them in successfully achieving this major milestone. We have been developing our lithium-ion battery testing capabilities for some time and we will continue to expand and invest in this exciting area.  We are looking forward to supporting Britishvolt with their further testing requirements in the near future."

Allan Paterson, Chief Technical Officer, Britishvolt:

“At Britishvolt, we are incredibly pleased to be working with AIS, to utilise their expertise and to help support validation of our technology in terms of safety performance. Safety is a key metric in battery cell manufacturing. This is fantastic news, and highly encouraging that we have worked with AIS to qualify our first product samples for transportation safety testing, putting us on a path for our future development and enables us to ship test hardware to customers.”

Based in Blyth, Northumberland, Britishvolt is Britain’s foremost investor in battery technologies. Their confidence in our service is a testament to our efficient battery testing capability.
