One of Aptera's most interesting technologies is that of using the underside of the body shell as a radiator to dissipate excess heat by molding-in coolant channels. This video is the result of a partnership between Munro & Associates and Sabic (thermoplastics) that saw them collaborating to redesign the Volkswagen ID4 battery pack. As Founder Chris recently said, every 15 lbs. of excess weight equates to a 1% drop in efficiency/range: The Munro/Sabic team removed 150 lbs. from the VW pack while making it stronger, easier to produce AND fire-retardant! The ID4 models feature ranges from 240-260 miles: This weight savings alone could (following the "Anthony Rule") equate to a range increase to 264-286 miles. One of the techniques Munro/Sabic employed was to mold coolant channels directly into the FRP (fiber-reinforced plastic) case of the battery pack - explaining why I've shared this video!
