How To Protect Your Lithium Batteries?


Lithium battery (rechargeable) is required for protection, it is determined by its own characteristics. Because the lithium battery material itself determines that it cannot be overcharge, over discharge, short circuit and ultra high temperature, lithium battery charge and discharge, so the components always followed by a fine protection board and a current for the presence of insurance.

The protection function of lithium battery protection circuit board usually consists of PTC and current of the device work cooperatively, the protection board is composed of an electronic circuit, at -40 DEG to +85 DEG C under the environment of current monitoring time accurate electric core voltage and charge discharge circuit, to control the current loop off; prevent bad battery PTC the damage in high temperature environment.

Common lithium battery protection board usually includes control MOS, IC switches, resistors, capacitors and auxiliary devices FUSE, PTC, NTC, ID, memory, etc. The IC control, MOS control switch in all normal circumstances, the electric core and the outer circuit, and when the voltage or current loop exceeds the specified value, it immediately to control the MOS switch off protection, electric core security.


In order to better serve to our customers, we also provide you some high-quality protection board, and be evaluated as the most professional PCM supplier of electric tool batteries in 2014. 

Currently we always provide 1-26S PCM, the most current can reach 150A, and 80A is our popular type.

Guangzhou new energy vehicle production increase two times from January to July

August 30, the Guangzhou Municipal Bureau of Statistics official website released data that the city's smooth economic operation from January to July, the main economic indicators have fluctuated, the overall stability. Among them, industry, consumption growth was flat in the first half year, investment growth slowed slightly. Guangzhou to implement the structural reform of the supply side has gradually markedly, new energy, a new generation of information technology, new materials, product output to maintain growth doubled, driven by corporate profits were recovering faster growth. The new energy can be used in solar powered portable generator.

High value-added new products to increase the rapid growth of corporate profits

January to July, Guangzhou to achieve above-scale industrial output value of 1.087773 trillion yuan, above-scale industrial added value of 269.214 billion yuan, up 6.8% year on year growth rate was flat with the first half.

The gross output value of the three pillar industries increased by 8.9%, and the growth rate was 0.4 percentage point higher than that of the first half year. Among them, the automobile manufacturing industry grew by 11.6%, the electronic products manufacturing industry increased by 11.8% and the petrochemical industry increased by 1.7%. The latter two grew faster than the first half year.

Among them, the three pillar industries of new products momentum is good. The new products of automobiles maintained a rapid growth. The output of new energy vehicles and sport utility vehicles (SUVs) reached 2,352 units and 568,100 units respectively, up by 2 times and 79.2% respectively. In the new information technology products, Devices, fiber optic cable production increased by 2.2 times and 33.4%; new materials, lithium-ion battery products were doubling the growth trend, the output growth of 1.2 times.

High value-added new products to increase, as stimulating industrial enterprises profit recovery was one of the reasons for the rapid growth. The first half of this year, industrial enterprises above designated size realized total profit of 53.922 billion yuan, an increase of 16.4%, but the growth rate from January to May fell 4.1 percentage points. According to previous public figures show that in the first half, new energy vehicles, optoelectronic devices, lithium-ion battery production respectively achieved year-on-year growth of 3.9 times, 2.6 times, 1.3 times, it include LiFePo4 battery pack.

Fixed asset investment growth rate of 12.7%

Investment in fixed assets, the total investment amounted to 492.227 billion yuan, the overall growth rate of 12.7%. Since the first half of this year, industrial investment has been rising since the decline, its growth rate continues to accelerate, an increase of 15.4%, the growth rate of 2.7 percentage points higher than the city's investment. In investment in services, investment in industries related to producer services and cultural life increased rapidly. Investment in leasing and business services, education, culture, sports and entertainment increased by 2.0 times, 1.1 times and 18.8% respectively.

January to July, the city's total retail sales of social consumer goods 492.227 billion yuan, an increase of 8.4%, growth was flat. At the same time, consumer prices (CPI) rose 2.6% year on year, PPI fell 2.5%, and purchase prices fell 4.6% year-on-year.

The retail sales of daily necessities, cosmetics, Chinese and Western medicines and gold and silver jewelry increased by 25.0%, 24.7%, 15.3% and 12.2% respectively over the same period of last year, which was in line with the improvement in the quality of consumption and quality improvement of residents. Accounting for nearly 30% of the above-mentioned auto retail sales growth of 6.4% in the first half growth rate of 5.9%.

Specifically, the export growth rate down, imports fell to expand. However, Guangzhou's cargo throughput, airport cargo throughput, airport passenger throughput, port container throughput growth rate has expanded.

From January to July, the growth rate of revenue and expenditure and the growth rate of total tax revenue all have some callback. Among them, the "battalion change" the full implementation of the impact, which accounted for over 60% of the national tax revenue growth of 5.4%, the growth rate than the first half increased 2.2 percentage points; land tax revenue growth of 5.7% growth rate down 8.1 percentage points.
