Although the battery may be used in relatively cold climate, they have a lot of limitations When the temperature reach to 20 ℃, the most battery performance can achieve the best level of only 50%, and when the temperature was minus 40 ℃,Lithium ion batteries performance can only be reached to about 12% of its capacity at room temperature.

Qichen Chenfeng electric vehicle battery 10 years later, really as official said still can maintain 80% of battery capacity? For consumers is most concerned about battery life, Qichen rather attractive repurchase program is given, which USES five years later, will be based on 30% of the purchase price as repurchase price, that is to say naked price now is about 170000 in the Chenfeng electric car after five years of the repurchase price in 50000 yuan But Qichen Chenfeng electric vehicle battery has a decisive influence for the repurchase price.

Battery bulge affect after use, put not into the mobile phone or digital camera, the other battery plate between the presences of gas can also affect the charge and discharge capacity of the battery Deflated can restore the original size, after normal use.

Since lithium-ion batteries available around it research and development work has been in constant Lithium ion batteries anode material has always been a debate topic, today let's talk just lithium iron phosphate (LiFePO4) as the cathode material lithium iron phosphate batteries。Lithium iron phosphate battery full name should be lithium iron phosphate lithium ion battery.

Learns from the state administration of market regulation's official website, a few days ago, Dell (China) co, LTD.

The solar energy battery board's role is to convert the sun's light energy into electrical energy, the output direct current in the battery Solar panel is one of the most important components of solar power generation system, the conversion rate and service life is to determine whether solar cell has the use value of important factor.

Wide use notebook computer, walkie-talkie, portable DVD, instruments and meters, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment18650 lithium ion batteries granddaddy of Japan's SONY company in order to save cost and set a standard of lithium ion battery model, including 18 said to 18 mm in diameter, 65 said length is 65 mm, 0 means for cylindrical batteriesCommon18650 battery divided into lithium ion battery, lithium iron phosphate batteries.

In the conditions stipulated in the design (such as temperature, discharge rate and termination voltage, etc), the battery should be able to release the lowest capacity, unit for ampere hour, expressed as a symbol of C.

The lithium battery charging ratio of C: used to say battery when charging and discharging current size ratio, namely the ratio As the 1200 mAh battery, 0.

The reason:A) Aging sealant lead to seal a crack;b) The battery serious charge, a mixture of different type batteries, battery gas recombination efficiency is poor;C) Pouring acid as acid spills, resulting in leakageThe solution:1) Wipe may be false leakage battery, late for observation;2) Change of discharge the battery.
