On the second day of the Spring Festival this year, Ji Wei.com took the lead in reporting the news that “OPPO R9 squeezed Apple into the best-selling model in 2016”. Since then, this topic has become a hot topic in conjunction with Apple’s financial report data. However, the current glory of OPPO may not be a flash in the pan, but the general trend is coming!

According to media reports, although the first quarter was the traditional off-season of smart phones, OPPO's latest flagship smartphone R9s took the lead in additional orders after the Chinese Lunar New Year, and urgently requested goods from the mainland and Taiwan smartphone industry chains, and announced the first. The quarterly shipment target will be raised from the original 2,800 to 30 million units to 3,000 to 32 million units, an increase of about 10%.

According to the report, OPPO has successfully won the top spot in the Chinese smartphone market. The popularity of the first quarter also allowed OPPO's previous shipments to increase by more than 20% in 2017, challenging the target of 1.4 to 150 million units, which has already completed 20%. At present, Huawei and vivo explosive shipments are still in the warm-up phase.

At present, in terms of supply chain, OPPO is likely to become the number one smartphone shipment in China in 2017, which will also pave the way for OPPO to become China's smart phone leader in 2017 and promote the top three global smartphones. .

According to the analysis, OPPO has seized the domestic white-collar users and complied with the terminal consumption upgrade. The channel strategy has also begun to move from second- and third-tier cities to first-tier cities. In addition, the OPPO mobile phone has a high unit price and large sales volume, which makes it a big advantage both in the upstream of the supply chain and in the terminal distribution market. These will become the capital of the 2017 OPPO.

In addition to OPPO, it is expected that there will be big moves in vivo and Huawei in 2017. The expectation of vivo is 30% in 2017, reaching 1.3-140 million units. Huawei is in the 1.5 to 160 million units.

Battery Energy Storage System

Battery Energy Storage System (BESS) is a complex system that integrates multiple technologies and devices to store electrical energy in the form of chemical energy and release it for use when needed. The following is a detailed description of the purpose of the BESS class:

I. Basic definition
BESS is a system that uses lithium batteries, lead batteries, etc., as energy storage carriers to store electricity for a certain period of time and supply electricity when needed. The power provided by the system has functions such as smooth transition, peak cutting and valley filling, frequency regulating and voltage regulating, etc. It is of great significance to improve the stability, reliability and flexibility of the power grid.

Second, system composition
BESS mainly consists of the following parts:

Battery Array:
It is the core part of BESS and is used to store electrical energy. Common energy storage batteries include lithium-ion batteries, lead-acid batteries and so on.
The performance of the battery directly affects the efficiency and reliability of the entire energy storage system.
Battery Management System (BMS) :
Responsible for intelligent management and maintenance of each battery unit, prevent the battery from overcharging and overdischarging, and extend the service life of the battery.
Monitor the battery status, including voltage, current, temperature and other parameters, to ensure the safe operation of the battery pack.
Energy Storage converters (PCS) :
It is one of the key devices in BESS, responsible for converting direct current in the battery pack to alternating current, or alternating current to direct current, to meet the needs of different application scenarios.
PCS has the ability to control the flow of electric energy bidirectional, and can flexibly adjust the power and voltage of the grid.
Local controller:
Responsible for local control and management of BESS, including data collection, condition monitoring, fault diagnosis and other functions.
The local controller can also communicate with the external energy management system (EMS) to receive instructions and perform energy scheduling and power control.
Power distribution system:
Devices such as switches, circuit breakers, cables, etc. are included to connect BESS to the power grid or other loads.
Distribution systems need to ensure the safe transmission and distribution of electrical energy.
Auxiliary equipment:
Including temperature control system, fire protection system, lighting system, monitoring system and so on.
These devices are used to ensure the safe operation and routine maintenance of BESS.
3. Technical characteristics
High efficiency:
BESS has high energy conversion efficiency and charge and discharge efficiency, which can maximize the use of stored electrical energy.
Flexibility:
BESS can be flexibly configured and expanded according to actual requirements to adapt to different scales and scenarios.
Reliability:
With advanced BMS and PCS technology, BESS is able to ensure the safe operation and efficient utilization of battery packs and improve the reliability of the system.
Environmental protection:
BESS uses renewable energy for energy storage and power supply, reducing dependence on traditional energy sources and environmental pollution.
