Rooted in the industrial chain with power batteries as the core, we have to look at the industry in the ups and downs of policies; In the wind and cloud of capital, forecast the direction of the pattern; In the generous debate of the experts, condense their own viewsAnd this industry is still rapidly developing, in the face of the overwhelming media reports, the author also has some of his own opinions, in the form of comments with you to do a share, the right to throw a brick.

As early as 2006, Dell recalled 4 million laptops due to battery problems; At the end of 2015, the electric car made by the technology giant Tesla was ignited by the spontaneous combustion of lithium batteries In April, Toshiba faced a bottleneck in the development of mobile phones because of the flaws in its laptop lithium-ion batteries.

Recently, from January to April, the license number of pure electric vehicle traffic insurance in Beijing was released, and the total license number of saic roewe reached 1753, among which the roewe ERX5 and roewe Ei5 were the first and second place respectively Compared with before, Beijing pure electric vehicle traffic insurance number one position, often occupied by byd brand, roewe can in January to April this year on the number of Beijing pure electric vehicle traffic insurance number one, shaking byd's market position is really not easy.

Nickel metal hydride battery is a kind of battery with good performance Nickel-metal hydride batteries are divided into high voltage nickel-metal hydride batteries and low voltage nickel-metal hydride batteries.

Sandwiches, many of us have tasted, but today's technology visibility "sandwich" is amazing It can turn our traditional power storage battery into a small power plant, and the biggest difference from traditional batteries is that, It's also a clean energy source.

First, correctly grasp the charging timeAfter the new car is proposed, it must be recharged in time to keep the battery in full state In the process of use, according to the actual situation to accurately grasp the charging time, reference the usual use of frequency and mileage, self-control charging time.

Lithium-ion rechargeable batteries have been equipped with many portable products, but many problems have to be recycled and replaced due to battery fire accidents and failures Battery manufacturers and product manufacturers are trying to ensure reliability and quality, but the problem has not yet been completely resolved.

The purpose of developing electric vehicles is to save energy and reduce emissions The automotive power must rely on independent intellectual property rights to produce electric vehicles with the lowest energy consumption and the lowest emissions.

The lithium battery voltage platform is high: the average voltage of the single battery is 37 V or 3.

The second part is the shape letter code, "R" stands for the cylinder, "S" stands for the square, "F" stands for the square (chewing gum) shape; the third part represents the battery size; the fourth part is the battery operating characteristic code, "M" stands for medium rate discharge, "H" stands for high rate discharge, and "S" stands for high temperature (100-150 degrees Celsius) For example: ER14500MS, which means that it can accept medium-rate discharge under high temperature conditions, with a diameter of 14.
