The latest developments in battery technology, motor control and power electronics are driving up capacity and increasing efficiency to squeeze the last drop of energy out of battery packs. Machine learning techniques are being used for softswitching motor control for efficiency levels that are approaching 100%, while space-saving axial flux motors are coming of age, as detailed on page 64. The importance of range has been shown by the latest solar-powered recreation vehicle, detailed in Grid starting on page 6. The first version had a range of 100 miles, but the latest version, which uses GM’s Ultium 800 V battery pack and power architecture enhancements, boost the range to 250 miles. The latest technologies addressing the thermal challenges to boost the performance and range are detailed in our report from this year’s Battery Show North America, on page 44, alongside the latest advances in motor control (page 34) and power electronics (page 58). As ever, the debate of range anxiety lags the reality of the engineering advances across the industry. Higher density battery cells, pack design, motor control and power electronics all continue to advance the performance of e-mobility platforms, which will eventually mean the end of range anxiety.
