Ordinary car batteries use lead-acid batteries, the cycle life is basically 200-500 times, and the service life is about 2-4 years With automatic start-stop function of the car, with a special battery, cycle life will be a little higher, 400-800, the service life of the basic four years to six years.

With the increasing global pollution, energy conservation and environmental protection seems to have become a large part of our lives Everyone has the responsibility and obligation to care for the environment.

Lithium polymer battery (Li - polymer) is on the basis of the lithium ion battery with polymer electrolyte to replace the traditional organic liquid electrolyte The polymer electrolyte that can be used as the transmission medium of ions, and can be used as isolation membrane, and the reactivity of metallic lithium is extremely low, thus effectively avoid the lithium ion battery of easy combustion and leakage phenomenon.

First, industry status quo (1) Industrial overcapacity has emerged In 2017, China's new energy vehicles sold 777,000 units It is expected that China's new energy vehicle sales will exceed one million units in 2018.

1 Speeding, danger is hard to control After all, electric vehicles belong to the range of bicycles.

First, the introduction With the development of pure electric vehicles and hybrid vehicles, the series battery pack, which is an important energy storage device, is a key factor affecting the performance of the whole vehicle Extending battery life and improving battery efficiency is the key to commercialization and practical use of electric vehicles.

With the increasing energy density of lithium-ion batteries, traditional lithium cobalt oxide materials are gradually being replaced by higher-capacity ternary materials Although ternary materials have a layered structure similar to LCO, compared to LCO materials, ternary materials not only greatly improve the material capacity, but also have better thermal stability than LCO materials.

The maximum charge termination voltage of the 12V battery is 168V, and the rated online working voltage is 14-14.

People always find the ipad can't work normally If it is useless to hold the switch of "home" and "power" for a long time, or connect itunes, etc.

1, Use voltmeter and load it to test the battery capacityHow to judge electric vehicle battery capacity? Test battery capacity, voltage of only using a voltmeter or multi-meter block without load to check whether the battery capacity is enough, it is difficult to accurately Just measure the voltage, the current consumption is few, so will have big pressure drop inside the battery, so according to the voltage is not low, but with quite a load, such as open headlight (load current 10 ~ 15 a), the horn (load current 6 ~ 12 a), the battery will dim the lights, horn husky, which shows a lack of electricity.
