I. The trend of the price index of China's mobile phone market The price index of mobile phone has increased by 2.74 points This week, the price index for mobile phones was 98.77 points, an increase of 2.74 points over the previous month. This is the second time in nearly eight weeks that the mobile price index has seen a substantial increase. In the four weeks of March, the mobile phone price index rose for four consecutive weeks and approached 100 points. In April, it fell for two weeks in a row, rebounded slightly in the third week of April, and rose again in the fourth week, but it was still 0.62 points lower than in the last week of March.
Judging from the average price, the average price of the mobile phone market this week was 2,233 yuan, up 62 yuan from last week. ZDC monitoring data showed that the number of vendors participating in the competition in the mobile phone market increased by one in this week, but it decreased by 33 in the sales model.
Second, China's smart phone market price index trend Smart phone price index rose 2.53 points ZDC monitoring data show that this week's smart phone price index was 91.89 points, up 2.53 points last week, which is the first time in four weeks the smart phone price index rose to 90 Above. In the four weeks of March, the smartphone price index rose continuously, rising from 89.97 points to 92.67 points. In April, there was a two-week slide. The average price of smart phones this week was 2251 yuan, which was 65 yuan higher than the lowest point in the second week of April.
Note: The ZDC price index is the most influential index reflecting the trend of price fluctuations in the Chinese IT market. The index was first publicly released on February 21, 2011, the base period was January 1, 2011, and the base period index was set at 100.

The main function of the Home Energy Storage System is to store the electricity generated by the solar panels in the home photovoltaic power generation system, so as to continue to supply electricity at night, cloudy days, or when the electricity demand exceeds the supply of the solar panels. It is an energy storage solution for improving the self-sufficiency and energy efficiency of home photovoltaic power generation systems.
Main effect:
Energy Storage: The Home Energy Storage System uses batteries to store excess electricity generated by the home's photovoltaic power generation system. When solar panels generate more power than the household needs, the excess power is stored in the battery to continue supplying power when needed.
Power supply backup: At night, on cloudy days or when the power generated by solar panels is insufficient, the Home Energy Storage System can use the stored power to continue to supply power to ensure the continuity and stability of household power consumption.
Energy balance: The Home Energy Storage System helps to balance the energy difference between the electricity generated by the home photovoltaic system and the electricity demanded, thereby optimizing energy management and maximizing self-sufficiency.
Differences from other energy storage systems:
Power source: The power source of the Home Energy Storage System is the Solar Panel of the home photovoltaic power generation system, which directly generates electricity by converting sunlight. While other energy storage systems may come from other renewable energy sources, such as wind energy, hydro energy, or non-renewable energy sources, such as grid electricity.
Renewable: The Home Energy Storage System uses solar energy as a power source and is a renewable energy system. Other energy storage systems may utilize different types of energy sources, with varying degrees of renewability.
Application Scenario: Home Energy Storage System is mainly used in home photovoltaic power generation systems, especially in conjunction with solar panels. Other energy storage systems can be used in different energy generation systems, selected according to specific energy sources and application requirements.
Overall, the main function of the Home Energy Storage System is to store the electricity generated by the solar panels for continued supply of electricity at night, on cloudy days, or when the home's electricity demand exceeds the supply of the solar panels. Compared with other energy storage systems, it uses solar energy as a power source, is a renewable energy system, and is mainly used in household photovoltaic power generation systems to improve energy utilization efficiency and self-sufficiency.
