The fixture applies a constant stack pressure to the face of the battery through the pneumatic actuator and is transferred through two carbon-inlaid 3D-printed plates. This material electrically isolates the battery to prevent the risk of short circuits and provides sufficient stiffness to improve pressure distribution.
After selecting a battery and performing required load testing ,the enclosure and mounting schemes are developed. Here are some of our tips and best practices for developing battery mounting schemes: Heat causes batteries to swell and therefore clearance is needed to absorb the swelling. Some clearance is necessary within limits.
Aluminum as sheet and extruded profiles is the preferred material for BEV body structure, closures and battery enclosures. Aluminum battery enclosures or other platform parts typically gives a weight saving of 40% compared to an equivalent steel design. Aluminum is infinitely recyclable with zero loss of properties.
Mechanical structures can be attached to strategic locations on a board to ensure meeting ruggedization requirements. These include ribs, stiffeners, hold-down clamps or brackets, spring retaining clips, adhesives, rubber pads, and encapsulation materials. Battery performance is subject to environmental factors such as air density and temperature.
Heat causes batteries to swell and therefore clearance is needed to absorb the swelling. Some clearance is necessary within limits. Too much clearance may cause your battery to rattle around in your enclosure. Loose parts give the impression of cheap design and can actually lead to damaged batteries.
Here is an example of a very compact design where the battery is nested in a compliant cavity for this hand held application: It is often necessary to perform thermal analysis to manage heat dissipation. Battery placement is critical. Typically, a small battery should be near an enclosure wall.
