Battery Wire Bonding Services

Offered from our demonstration facility in Cambridge, Accelonix’s prototype and small volume EV and heavy wire battery bonding services support customers in early stages of their battery pack prototyping project. The current momentum for vehicle electrification intensifies the ever-increasing need for rapid prototyping and small batch production to validate and give life to a proof of concept. With equipment delivery lead times becoming even longer due to strained supply chains, Accelonix is committed to support the electronics industry and allow our customers the ability to produce a battery pack within a short timescale.

Battery Wirebonding
Ultrasonic wire bonding battery pack production

Ultrasonic wire bonding can be used in battery pack production to create current-carrying connections between cells, cell to busbar, cell to PCB, cell to a battery management board (BMB) or battery management system (BMS) as well as contacts for cell voltage monitoring. A high level of automation of the wire bonding process ensures reliable and low resistance connections, whilst wire bonds act as fuses in the event of an overcurrent condition in a battery (fuses can be added to protect the wire bonds in the case of a larger overcurrent condition). 

Our team of factory-trained and highly skilled engineers uses Hesse GmbH’s market-leading BondJet BJ985 Fully Automatic Heavy Wire Bonder without burdening your own resources and without having to wait for your own production machine to be delivered. We can bond with various materials including wire and ribbon, and we can accommodate a wide range of battery pack sizes as well as provide training and application support.
