Lithium battery for low speed electric vehicle
Before purchasing a lithium battery, check whether the battery cells used are grade A. The quality of the battery cells determines the quality of the battery, for example as capacity and energy density. Wait, second, find a lithium battery produced by a major manufacturer with mature production technology and guaranteed after-sales service. The market reference price of lithium battery is 1,250 yuan/KW.H. If you have to travel a long distance, it is best to install a range extender. With it, you won't be afraid of running out of energy halfway and it can help you travel worry-free.
Since the cruising range of low-speed four-wheel electric vehicles is still relatively limited and cannot fully meet the daily travel needs of the public, if you wishIf you want to increase its cruising range, you can install an extended range. Increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and travel back and forth freely, without more difficulty due to lack of power midway.
You can buy the range extender directly from the manufacturer, and they will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a major manufacturer and a major brand to have all the guarantees in terms of quality, performance, manufacturing and after-sales service. Otherwise, if it is a small workshop type manufacturer, it will be easy to break and there will be no guarantee in all respects.
Recommendations for using the range extender:
It is not recommended to start the range extender when the battery is full. HeIt is generally recommended to start the range extender when the battery is only charged. 30%-40%. There is no particularly good effect when starting when the battery is full. For the sake of respect for the environment, it is recommended to start the range extender when necessary. Battery pollution is more serious than exhaust pollution. It is not recommended to use it when the battery is low on electricity. The range extender starts electrically. If the battery is low on electricity, it may not start.
Recently, according to foreign media reports, Europe's largest lithium-ion battery system manufacturer, BMZ Group (BMZ Group), will purchase 1 trillion won (about 6. 1 billion yuan) of lithium-ion batteries.
BMZ Group CEO and founder Sven Bauer and Samsung SDI Senior Vice President Michael Son had already startedheld relevant negotiations in South Korea in early December 2018.
A Samsung SDI executive said that the company has been cooperating with BMZ Group for a long time and the two sides are currently negotiating future battery supply cooperation, but the size of the transaction has not yet been determined.
Information shows that BMZ Group is a global lithium-ion battery solutions provider headquartered in Germany, with production bases in China, Poland and in the United States, as well as in Japan and offices in France. In addition, the BMZ Group also has R&D centers around the world.
Since 1994, BMZ Group has provided professional customized battery system solutions to more than 2,000 world-renowned enterprises, covering power batteries, storage systems energy, medical and industrial equipment, outthey electric. and other application areas. ProduceProducts include: electric vehicles, battery-powered bicycles (E-Bike), ESS energy storage systems, mobile medical equipment, power tools, cordless drills, electric screwdrivers, electric gardening tools , etc.
It is worth mentioning that BMZ Group plans to double the production of electric vehicle battery systems supplied to major European automobile manufacturers next year to further meet the market demand. Acquired German battery manufacturer TerraE plans to invest 300 million euros to build an 8 GWh battery production line. The production capacity of the first phase is expected to be 4 GWh and is expected to be put into production in 2020.
As the world's leading power battery industry giant , Samsung SDI achieved performancesoutstanding performance in terms of market cooperation performance, production capacity expansion and technological progress since this year.
Financial data shows that Samsung SDI's sales in the second quarter of this year were 2.25 trillion won and its operating profit was 152 .8 billion won, an increase of about 28 times over the same period. last year (the second quarter of 2017). In the first quarter, Samsung SDI's operating profit was only 5.5 billion won, when the company posted six consecutive quarters of losses due to fallout from the Galaxy battery explosion crisis Rating 7 in 2016). Among them, battery sector sales amounted to 1.73 trillion won, an increase of 21.9 percent from the previous quarter.
In terms of commercial cooperation, in October, mKorean media reported that South Korean Hyundai Motor Group plans to cooperate with Samsung SDI to develop electric vehicle batteries. In September, it was announced that Samsung SDI would supply cylindrical batteries to Jaguar Land Rover's electric vehicles. It is initially planned to supply batteries with an annual capacity of 5 GWh. In March, Webasto and Samsung SDI signed a letter of intent for cooperation at Webasto headquarters in Stockdorf, Munich, and plan to cooperate in the manufacturing of high-voltage batteries for commercial vehicles.
In terms of production capacity expansion, in November this year, Samsung SDI plans to open an automobile battery factory worth 62.7 million dollars near Detroit, Michigan. The plant will serve as Samsung SDI America's battery pack manufacturing facility, R&D center and headquarters for automobi battery operations.THE.
In December, the new second-phase factory project of Samsung Ring New Power Battery, a Chinese subsidiary of Samsung SDI, started in Xi'an, with full investment of 10.5 billion yuan and a construction zone. of 160,000 square meters, after the project is completed, five 60 Ah lithium-ion battery production lines will be formed.
In the same month, Samsung plans to invest another $2.4 billion (about RMB 16.5 billion) in the Tianjin factory to build the world's first power battery production line and an automotive MLCC. (multilayer ceramic capacitor) and other new projects.
In terms of technological progress, the current energy density of Samsung SDI third generation power battery is 550 Wh/L, and mass production has been achieved . According to Samsung SDI's plan, pre-The energy density of batteries3.5th generation, mass production of which is planned for 2019, can reach 630 Wh/L.
At the same time, Samsung SDI is also accelerating the research and development of fourth-generation batteries and fifth-generation batteries, with energy densities reaching 700 Wh/L ( equivalent to 270 -280Wh/kg) respectively and 800Wh/L (equivalent to 300wh/kg), which are expected to be mass-produced around 2021~2022 and after 2023 respectively.
It can be seen that Samsung SDI's meteoric expansion is the epitome of the accelerated global expansion of Korean power batteries. Currently, electric battery giants, including LG Chem and SKI, are also accelerating the distribution of their production capacities in the European, American and Chinese markets. Under the new globalization of energy and the timing of subsidy withdrawal in 2020, Chinese electric battery companies arent destined to face global competition. How to deal with the close combat of Japanese and Korean electric battery giants has become a problem for Chinese companies at present. we have to face it.
