Hybrid’s Liquid System Allows Chevy to Offer Cool Warranty
The liquid heating and cooling system in the Chevrolet Volt battery not only enabled General Motors Co. to offer a long warranty of eight years or 100,000 miles, but it also gave engineers more room for battery cells since it’s more compact than air-cooled systems, but it also. Standard auto coolant circulates through 144 metal plates, called fins, between each of the Volt … [Read more...]
Mercedes Electric Supercar Features Two Cooling Systems
Mercedes has rolled out a prototype of its new SLS AMG E-CELL electric supercar, which looks set for small series production. The prototype features four electric motors positioned near each of the wheels, which produce 392 kW and 880 Nm of instantaneous torque and acceleration of zero to 100 km/h in 4 seconds — just 0.2 seconds under the performance of the 6.3-litre V8 SLS … [Read more...]
