![]() ![]() After some testing, we found that a two-part polyurethane from Wevo-Chemie (a German company that specializes in casting, bonding, and sealing resin solutions) had the highest thermal performance, so it became a critical component in our system as an adhesive.” “Passive cooling means that the thermal conductivity of the materials that surround the cells is very important. We describe it as being passively air-cooled, and it helps keep the weight down significantly. I will say that the system allows us to very effectively cool the battery using passive (air-cooled) methods, with no need for liquid cooling. Alta builds its own electric motorcycle battery pack and thermal management system with help from two companies you have probably never heard of. Kevin Kim, Alta’s head mechanical engineer, explains: “Unfortunately we can’t disclose too many details about the interconnect system because it’s proprietary. But how you put them together makes a big difference. We believe the Model 3 will probably be on par with where we are today, although they haven’t announced numbers yet, so we can’t calculate it,” says Rob Sweney, Alta’s director of advanced powertrains.īattery cells are battery cells. “We’re right around 180 Wh/kg, which is about 20–30% higher than the current Tesla Model S. The result is an electric motorcycle battery with higher energy density than virtually any other battery in a production vehicle. Even though it begins with the same 18650 lithium ion battery cells as Tesla uses in its Model S and Model X cars, it packages them in a way that is unique to Alta. To do that, it needs a great battery that is both powerful and light in weight. The Alta Redshift MX electric motorcycle is designed to compete successfully against the best off-road bikes in the world. ![]()
