In both digital and application in power market,Soft package battery is becoming a very important technical routeSoft pack batteries, it is to use the batteries of aluminum-plastic packaging film as packing material.

The lithium battery(rechargeable) are needed to protect, is determined by its own characteristicsDue to the lithium battery material itself determines its cannot be overcharge, discharge, over current, short circuit and charging and discharging, high accordingly lithium battery Li-ion battery components will always follow a delicate protection board and a piece of current fuse.

Power lithium battery with groups, each section lithium battery take charge over voltage, discharge under voltage, over current, short circuit protection, in order to realize the whole charging process battery equalizing charge, with one section introduces a lithium battery protection chip for any number of series group including equalization charging of lithium battery protection function of battery protection board designThe simulation results and industrial application prove that the protection plate protection function is perfect, stable work, high cost performance, equalizing charge error is less than 50 mv.

1, battery capacity The capacity of the battery is determined by the amount of active material in the battery, usually expressed in milliampere-hours MAH or Ah For example, 1000mAh can be converted to 1600 by the current discharge of 1A to a charge of about 3600C.

How to correctly view and read the current meter and voltmeter of the 12v battery charger is divided into the following steps: 1 Set parameters: 12V battery, 12V gear for charging, and 13% gear for battery capacity.

Recently, in April 2018, the list of new energy vehicle sales was released In April, the sales volume of new energy passenger vehicles reached 73,000 units, an increase of 31% from March and a year-on-year growth rate of 150%.

Electricity as a single power source of pure electric vehicles, unable to get rid of the dependence on charging pileElectric vehicle charging method has quick charge and slow filling two kinds, slow filling needs 6 hours or more, so fast charging pile can in a short period of time for electric charge, some people will feel very satisfied.

Now, the direction of the electric car is more and more tend to be more high-end intelligent developmentElectric car research and development of manufacturing technology in the unceasing progress, electric vehicle technology is mature.

The battery concentrate is dilute sulphuric acidWet type of battery is refers to the need to add battery Yuanye dry battery, if you don't twist open charging, sulfuric acid gas release is not good, easy to cause lead plate fall off, or explosion.

Lithium iron phosphate batteries than Tesla MODELS using the ternary lithium batteries in much higher energy density, weight is about 200 wh/kg, this means that the same weight of ternary lithium battery range is longer than the lithium iron phosphate batteriesBut its shortcomings are obvious, when its temperature is 250-350 ℃, internal chemicals began to decompose, thus puts forward high requirements on battery management system, the installation of insurance device need batteries separately for each section, in addition, due to the monomer volume is small, so the bike to battery monomer quantity is very large, MODELS, for example, more than 7000 day18650 the ternary lithium battery to meet the dosage of the assembly of a car, no doubt this again for the battery management system is further increased the difficulty of control.
