Lithium battery residual value is still high development of electric vehicles

The popularity of electric vehicles (EVs) is expected to add another opportunity. Research data from the United States General Motors (GM) show that lithium batteries with an astounding price for electric vehicles will have a battery life of 50 to 70% after more than eight years of decommissioning. Therefore, when the demand for energy storage equipment is soaring, it will bring a high value of additional utilization, which can reduce the initial high purchase cost of electric vehicles and further promote consumers' desire to purchase.

Zhao Yujie, an industrial analyst at the Metal Industry Research and Development Center, said that the target market for the initial promotion of electric vehicles will be a fleet with fixed routes and enterprise operations, such as logistics, taxis, and public office vehicles.

Zhao Yujie, an industry analyst at the Metal Industry Research and Development Center, said that the astonishing price of lithium batteries is one of the main reasons why electric vehicles are not yet universally used. However, with the continuous expansion of the nuclear disaster in Fukushima, Japan, more secure energy storage is needed. Equipment has received global attention, so the industry has focused on energy-efficient lithium batteries. According to research data from the Metal Center, lithium-iron batteries commonly used in electric vehicles can have a capacity of 70 to 80% after exceeding the battery life of electric vehicles; however, this data still needs to be further measured. Verification, but there is no doubt that this residual value has attracted the attention of the energy storage equipment industry, leaving electric car makers with confidence in future development.

Zhao Yujie disclosed that the current possible applications of lithium batteries for electric vehicle decommissioning are used cars, home and office spare energy, etc., and Nissan in Japan has previously measured through its Leaf electric vehicle model. The results show that after 5 years Lithium batteries on the car still have more than 80% electricity storage capacity, and each time reserve power can provide power consumption for the average home user for about 2 days, with extremely high additional benefits. In view of this, Nisshina has entered into a joint venture with Sumitomo Corporation and is expected to use second-hand batteries as storage devices. In 2016, it will create a solar battery storage system for use in commercial and public facilities.

On the other hand, electric vehicles may also be expected to create a new business model for electric power management. Zhao Yujie analyzed that due to the international use of time-of-use (TOU), tip/off-peak tariffs, and pre-paid electricity rates, bills for electric vehicles are The commercial concept of charging at peak hours and selling the excess purchased electricity back to the power company at peak hours has been gradually discussed by the industry. For example, V2G (Vehicle-to-Grid) is a new business, and the United States has a name called Nuvve's company began to operate this type of service, bringing an entirely new perspective to the development of electric vehicles.

All in all, to accelerate the pace of electric vehicles on the road, the most important link is the price of lithium batteries and the value of reuse. Zhao Yujie emphasized that the choices faced by consumers between conventional gasoline vehicles and electric vehicles often lie in the comparison of overall costs. Such as the initial purchase price, maintenance and repair costs, oil/electricity prices, charging equipment costs, etc., if the future on the benefits of second-hand lithium batteries can be further established, I believe that electric vehicles will be more market power.
