BHPian evhead recently shared their thoughts on why hybrids will not win the race. Prado replied that it’s unfair to generalize the term “hybrid,” pointing out that there are different types of hybrids, including series hybrid, parallel hybrid, and series/parallel hybrid.
Series hybrids use an IC engine only as a generator, charging the battery while providing no direct power to the wheels. Parallel hybrids, on the other hand, allow for a wider range of operating points, but often require specialized transmission arrangements. Series/parallel hybrids switch between high-efficiency mode and parallel mode depending on power demand.
Prado suggests that well-designed series/parallel hybrids could run mostly in series mode before the IC engine powers the wheels, allowing for efficient operation at high speeds. However, he acknowledges that this comes with some trade-offs, such as increased maintenance costs compared to electric vehicles (EVs).
On the other hand, BHPian Matrix_Maya raises a crucial concern about rare earth materials used in EV technology. With only a few suppliers controlling these materials, their availability could be a significant factor limiting the future of EVs.
BHPian Earthroamer also shares a valid point that current EVs require extended charging times to recharge from 10% to 100%, making them less practical for replacing traditional vehicles. However, they suggest that city transport EV scooters have great potential and may serve as a stepping stone towards more efficient electric solutions.
While hybrids show promise, it seems that the limitations of EV technology, particularly rare earth materials and charging times, hold them back from gaining widespread acceptance in the short to mid-term future.
