Japan studies battery of electric vehicle as backup power -Lithium - Ion Battery Equipment
According to foreign media, as one of the five largest energy consumers in the world, Japan is vulnerable to natural disasters such as tsunamis, typhoons and earthquakes. Any destructive natural disaster may bring the national energy supply into crisis. But at present, the Japanese government may have explored a new way to solve this problem.
It is reported that the local government of Japan is currently studying whether the battery of electric vehicles can be used as a reliable backup power supply to meet the power demand in an emergency. Local governments and electric vehicle manufacturers are strengthening cooperation to explore that when traditional energy cannot provide electricity, the latter will provide electric vehicle batteries for free.
As a big country in the production and marketing of electric vehicles, Nissan has sold more than 360000 Leaf models by 2018. A few days ago, Nissan announced that it would hold a press conference in March to show how to get rid of difficulties by using electric vehicles in the event of natural disasters, including overnight stay in the vehicle and the use of electric vehicle batteries to store electricity. Nissan officials said that the fully charged Leaf car battery can provide up to four days of power consumption for standard Japanese families.
In fact, the use of on-board batteries as emergency power has been unprecedented. As early as March 2011, a 9.0 magnitude earthquake in northeastern Japan triggered a tsunami, leading to a massive power outage in Tokyo. At that time, electric vehicles were used as batteries to power rescue stations and shelters. In 2012, Nissan's competitor Mitsubishi signed an electric vehicle borrowing agreement with Kyoto Prefecture. In 2016, after a strong earthquake of magnitude 7.0 occurred in Kumamoto County, southern Japan, Mitsubishi provided electric vehicles for communities in need. In 2017, Nissan began to promote electric vehicles as backup power supplies. Nissan said that natural disasters are likely to cause the failure of traditional power supplies in a day or two. At that time, the power stored in the on-board battery can meet the living needs of heating, cooking and communication.(Lithium - Ion Battery Equipment)
In 2018, Nissan reached an agreement with Lianma District of Tokyo and Yokosuka City to provide electric vehicles for free so as to provide power in case of emergency. In addition, Lianma District has also developed an electric vehicle sharing system to facilitate mutual assistance among community members.
In Japan, although electric vehicles are getting more and more attention from the public and the government, and various car enterprises are also actively distributing various types of electric vehicle sales, there is still a long way to go to achieve large-scale commercial production of electric vehicles. According to statistics, electric vehicles accounted for only 0.2% of Japan's road vehicles in 2018, accounting for about 1% of new car sales. It will take time for electric vehicle batteries to become reliable national backup energy.
