In the post-epidemic era, how should car companies choose reliable battery suppliers?

Under the outbreak, the test of electric vehicles on the upstream and downstream industrial chain is much greater than that of fuel vehicles. Many individuals or businesses are thinking about what posture to take to get through this crisis. Currently, China-EU policy has shown incentives for electric vehicles to support markets that have been held back by the epidemic. How should the car companies in the center of the whirlpool deal with the crisis, and what kind of help they urgently need? The growth space of electric vehicles is compressed by the epidemic? Under the influence of the epidemic, the economic downturn and the decline of consumption power are certain events. The International Monetary Fund (IMF) released the World Economic Outlook report, which shows that the new coronary pneumonia epidemic is expected to cause the global economy to shrink this year 3

Hidden dangers behind the three giants of Korean batteries

Despite the acceleration of the power business of the South Korea's three major battery manufacturers in 2019, it is still difficult to hide the anxiety of its eagerness to achieve profitability in the battery sector and the challenges it faces in the future. Affected by the acceleration of the global automotive electrification process, Samsung SDI, LG Chemical and SKI three South Korea battery giants have significantly accelerated the pace of construction of their global power battery capacity. At the same time, the above three battery companies also received huge battery orders in 2019, and the revenue of the battery business increased significantly, thus improving the profitability of the department and even turning losses into profits. According to the capacity layout location of the three enterprises and the time period of investment and expansion of production.

Annual analysis of lithium carbonate price trends in 2019: overall downward trend

Introduction mybattery lithium carbonate prices in 2019 can be described as falling into a trough, as the downstream market is shrouded in pessimistic expectations, lithium carbonate supply and demand is relatively unbalanced, lithium carbonate prices are still low volatility, the in stock market supply and demand pattern is still depressed. According to business agency data monitoring, lithium carbonate prices as a whole showed a downward trend in 2019. Although prices declined in the first half of the year, the decline was slightly more moderate. In the second half of the year, the market price of lithium carbonate began to fall sharply, until the end of the year, the price of lithium carbonate still did not see a positive phenomenon. On December 27, the average price of industrial lithium carbonate in East China was 44400 yuan

Lithium battery charging process, does long-term trickle charging affect lithium batteries?

锂电池充电过程，长时间涓流充电对锂电池有影响吗？锂电池使用日益广泛，使得锂电池充电方法备受关注。对于不同的锂电池，通常具备不同的锂电池充电方法，这也是大家无法短时间内全面掌握锂电池充电方法的原因。那么锂电池是怎么充电的呢？长时间涓流充电对锂电池有影响吗？下面小编带大家了解一下。 涓流充电是镍氢电池的说法，对锂电池同样适用，锂电池的充电过程可以分为四个阶段：涓流充电、恒流充电、恒压充电以及充电终止。恒压阶段就是所谓的涓流充电了，电量一般在80%左右，即可进入恒压模式，此时充电速度会开始变慢，直到将电池充满。 锂电池充电过程阶段1：涓流充电—涓流充电用来先对完全放电的电池单元进行预充，在电池电压低于3V左右时采用涓流充电，涓流充电电流是恒流充电电流的十分之一即0.1c。 阶段2：恒流充电—即充电电流恒定，就是我们常说的CC模式，恒流充电我们电流需要恒定，一般取充电电流在0.2C-1C之间，注意不要超过1.5C，否则对电池会有较大的损伤；这个过程中，锂电池的电压会不断上升，直达电池电压达到4.2V后进入恒压充电阶段。 阶段3：恒压充电—当电池电压上升到4.2V时，恒流充电结束开始恒压充电阶段，为使性能达到最佳，稳压容差应当优于+1%。 阶段4：充电终止—有两种典型的充电终止方法：采用最小充电电流判断或采用定时器，最小电流法监视恒压充电阶段的充电电流，并在充电电流减小到0.02C至0.07C范围时终止充电；第二种方法从恒压充电阶段开始时计时，持续充电两个小时后终止充电过程。 长时间涓流充电对锂电池有影响吗？锂电池经过快速充电和连续式充电两个阶段之后还需要进行涓流充电将剩余容量充满，涓流充电通常需要持续一段时间，三个阶段全部完成才能真正达到电量饱和的良好状态。目前充电器不能对锂电池的涓流充电过程进行控制，涓流充电的时间太长会有爆炸的危险，涓流充电的时间太短，锂电池容量没有充满而缩短锂电池的使用时间。 涓流充电是用来弥补电池在充满电后由于自放电而造成的容量损失，一般锂电池刚买进时要充电12小时，在充电器灯灭后的涓流充电时间不能断电。涓流充电能够把电池充得很足，而不伤害电池寿命，但用涓流充电所花的时间实在太长，因此很少单独使用，而是和其它充电方式结合使用。 许多电池制造商建议不要长期使用涓流充电。使用涓流充电，充电速率就会非常低并且有时断断续续。当给电池充电时，最好的智能充电器只能进行临时的充电速率变化，但没有连续的低速率充电功能，如果长期进行涓流充电只有十分之一的电池能量不会受到伤害。 以上就是锂电池充电过程介绍和长时间涓流充电对锂电池的影响。涓流充电最大的好处就是在充满手机前将充电速度降下来，有效的减少手机过充的发生，但是平时充电时，并非必须将手机充得越慢越好，而是以少吃多餐为宜，有时间就充，充好就接着用就行。文章来源：锂电池UPS
