Many government bodies are promoting the
use of electric vehicles (EVs). The environment-friendliness of these EVs
including electric cars has pushed major population to use them. However, people
face many issues while using these cars. Leakage, crack, and loss of storage
capacity of their electric cars batteries are some of them. Generally, while
charging these batteries, many fast-charging stations use high resistance and
high temperatures. This is one of the key reasons for damage to batteries. A
recent research offers a better way to improve the battery life of electric
Unique Technique That Allows Charging at Low Temperatures
Engineers from the University of
California, Riverside, stated that they have developed a new method to prevent
the battery damage of electric cars. Mihri Ozkan and Cengiz Ozkan led this study.
The latest charging method developed in this research is an adaptable system. Basically,
this system checks the internal resistance of the battery when it is in
charging mode. Moreover, it rests when internal resistance kicks in to avoid
loss of charge capacity. While explaining more about the research, Mihri Ozkan
stated, “Internal chemical and mechanical damage, capacity loss, and the high
heat for every battery are important safety issues. At present, there are around
4,416 lithium-ion batteries in a Tesla Model 3. In addition, this number goes
to around 7,104 in Tesla Model S.” This study is open for access in the journal
Besides, Cengiz Ozkan explained, “Our
unconventional adaptive fast charging algorithm decreased capacity fade. Moreover,
it eradicated fractures and alterations in the commercial battery cells’ composition.”
Thus, inner resistance charging resulted in no damage and considerably lower
temperatures. Bo Dong, co-author of this study, stated that the proposed
adaptive fast charging offers a new perspective for the design of fast charging
technology. As a result, the research will help in improving lifespan and
safety performance of batteries used for electric cars.”
The speed of sales of electric cars will be uncovered at the motor show in Geneva to be held this week. However, experts feel the switch to electric motors will undo the benefits that carmakers enjoy these days. This is because they poured billions of dollars into designing and enhancing internal combustion engines both to offer performance drivers and also to satisfy stringent regulations pertaining to pollution. So much so, it created a high barrier to entry of new players into the market.
An electric powertrain, on the other hand is much easy to produce. This is one area where relatively new players such as Tesla, which began mass production of cars just about ten years back, and Chinese carmakers are taking the lead. Around 30 companies have been identified in the electric car market.
Stringent Rules by Chinese Government to Reduce Air Pollution Promotes Market
In fact, a dekko at the major manufacturers of electric cars shows that manufacturers of electric cars are all set to topple traditional carmakers. For example, China’s BAIC holds the first place for having sold around 78,000 electric cars.
The Chinese electric car makers have all benefitted from the rules framed and implemented by the Chinese government to boost uptake of such less polluting vehicles. This is mainly to tackle the massive air pollution the nation is now faced with.
Chinese electric car makers have far surpassed their German counterparts, which are known to dominate the car market meant for the masses as well as luxury segments.
Electric vehicles (EVs) are foreseen to be the future of how humanity transports but this trend has emerged primarily on the increased environmental concerns. Fossil fuel reserves are limited and cause severe damage to the environment. Additionally, EVs offer quitter rides and instant acceleration. However, will electric vehicles be pocket-friendly or affordable to larger masses too? The jury is still out on that verdict.
As nearly every automotive players is developing their own brand of electric cars, the prices are falling consistently but they are still significantly costlier than the gas models, which is essentially due to the cost of batteries. A number of governments are offering tax rebates are well, which has helped erase the gap but there still is a large void to be filled.
Since eternity, price of the products has been of optimum valuation to the consumers. And consumers who are opting for electric cars are going for leased licenses rather than out rightly buying them for the sheer cost of the products. For instance, more than 57 percent of leaf electric cars from Nissan are on lease, as compared to only about 30 percent of all cars.
That being said, electric cars are cheaper to fuel and easy to maintain. For instance, a Leaf costs about US$600 per year to charge, according to the United States Government, which equates to nearly 15,000 miles per year. Consumers pay anything around US$1,050 on gas to fill up a Civic. Although, these figures are also dependent on the location of the vehicles.
