Battery Pack Manufacturing Process

Below are images from the battery pack manufacturing process. All our custom battery packs go through intensive testing and quality control during each step of manufacturing.

State of the Art Battery Manufacturing in New Bedford, MA
Temperature and humidity control, ESD protection, and specialized fire control equipment are just a few of the few of the requirements of a company if they want to work with companies like Sanyo and Panasonic.
IPC Certified Soldering
All of our soldering technicians are IPC trained and certified so that we can assure the highest level of quality on our product.
Spot Welding Process
The most attractive feature of newest spot welding equipment is that the energy delivered to the spot can be controlled to produce reliable welds.
Heat Shrink Oven
The Heat Shrink Oven shrinks tubing in a fraction of the time required by a heat gun as it reaches the optimum operating temperature to quickly and uniformly shrink tubing.
Soldering Stations
Our dedicated and ESD protected soldering stations allow us to manage multiple assemblies during our 24/7 operation.
Wire Cutting and Stripping
To optimize production rate, repeatability and accuracy of the wire length, Epec has continued to invest in equipment to ensure quality.
Ultrasonic Welding Equipment
Each custom battery pack that requires a plastic enclosure can be sealed by adhesives, mechanical screws or the latest in ultrasonic technology.
Pull Test Equipment
Used to measure the strengths of the tab welds on the cells to ensure that the connections last while in use.
Final Assembly
At this step all of the pieces are put together in the final assembly. These can include printed circuit boards, thermistors, membrane switches and many other products depending upon the features of the battery pack.
Custom Testing Equipment and Procedures
Battery testing is done on battery packs at both the prototype and production levels. Our in-house capabilities allow us the ability for programming and testing that may be required at the customer level.
