Winter temperature plummet: How about three lithium battery performance?

In 2015, with the strong impetus of the government, China's arms and sleeves drastically made China's new energy year. There are more and more new energy electric vehicles that shuttle around the society, private cars, taxis, express trains, special cars, black cars, and service cars…The new energy indicators that are easier to shake, state subsidies, tax exemptions, unlimited numbers, nominal orders to the property to assist in the installation of charging piles, non-electrified charging piles on highways, and other powerful policies, such as new energy vehicles stand in front of the people. Everyone cannot be ignored.

As a new energy owner of Beiqi 's ev200, the author has conducted a crude statistical summary of mileage in the summer. And because 2015 is, in my view, the real year of new energy in China, with the arrival of winter, the remaining half of the new energy car mystery will be torn down by the winter, completely in front of everyone.

The vehicle that the author drove was Beiqi EV200 light version, with a land price of 116,900. It uses a three-way lithium battery, which has better low-temperature performance and greater density. Therefore, for the same model, the EV200 of the three-part lithium battery can have a maximum endurance of 40 kilometers more than the EV 160 of lithium iron phosphate. The EV160/200, which was only fully sold in 2015 and has soared in sales, has basically not passed through a cruel winter. If its record is to hand over its first test paper, this is not only the test paper of Beiqi, but also the new energy. The test paper.

Here I do not intend to use obscure technical terms to explain, everything is easy to understand as a premise.

We all know that batteries are very afraid of cold temperatures. Let me tell you something true.

After a few days of unusually cold snow in Beijing, I happened to be out, leaving the office building before the iPhone6 plus the remaining 25 % of the electricity, and when you come outside, less than 3 minutes, 20 % of the electricity alert appeared, less than 20 seconds, 10 % of the low power warning also came…When I was ready to return to the office building, the electricity was only 1 %... After entering the building and arriving at the company by elevator, the temperature picked up and the power of the mobile phone was quietly recovered to 20 %.

This is all because of the characteristics of the battery, and this characteristic, no matter which new energy car company, the negative impact of its characteristics are common, and no car company is the same.

For our new energy electric vehicle, so large a battery hanging on the chassis, its response in winter what is the rule? With this curiosity, the author on the continued nearly 20 days of changes and summary, for everyone into the winter, the truest, the closest to the daily use of the owner of the renewal summary.
