Electric Evolution

Electric Evolution

The general feeling seems to be that motorists want a revolution, but not yet. As you’ve heard often enough before, the principal gripe is the issue of range. Electric cars simply can’t go far enough and even if they did there’s not, as yet, anywhere to charge them away from home. Yet things have to change. Even the most hardened petrol head is beginning to understand that there is an unstoppable driving force behind the evolution of electric vehicles.

In a recent American report it is reckoned that the cost of lithium-ion batteries will fall by about a third in the next four to five years as battery production technology improves, lithium supplies increase and battery packs are sold in greater volume. The report states that “ the market for Li-ion batteries will be driven primarily by plug-in hybrids. Battery electric vehicles require much larger packs than hybrids.”

It is the cost of the fuel cells that governs the industry’s current anomaly. Lithium-ion batteries present a classic ‘what comes first’ scenario. Battery costs need to decrease in order to yield a lower price on the forecourt to encourage the punters. Conversely, the power packs need to be produced in high volumes in order to get costs to fall.

Regardless, the demand for electric drive cars, especially amongst city dwellers, is expected to rise over the coming years; especially as the cost of conventional fuels continues to rise and car makers offer a greater range. The report estimates that the global sales of  plug-ins will rise to a figure in excess of 5 million by 2017.

Lithium is a mineral, the 31st most abundant element on Earth and is the lightest metal. Most of it is found in South America which has more than half of the world’s deposits. It can also be obtained from sea water in same quantities. Herein lies the problem. No car can be considered green. Powering a vehicle on a daily basis is always going to use some sort of resource. We stop extracting oil and start extracting lithium instead. When we’ve got all the lithium, then what? The answer is perhaps not to rush at any one power source but take time to investigate everything that is available to us. Right now the best thing to do is compromise. That is what ‘greener’ should be about. The Toyota Hybrid Synergy Drive and other systems seem the best way forward right now. One million Toyota Prius owners can’t be wrong.
