Can you still rent a shared charger after a power outage?

Many people use shared rechargeable batteries when they go out. Which is a relatively common electronic product that is easy to use and brings convenience to people. Shared rechargeable batteries generally need to scan the code to rent. So if the power goes out, can you continue to use it?

DuDu has a power supply inside the cabinet. So when the power goes out at the place where the rechargeable battery is placed. We can still support the rental and return of the rechargeable battery. This prevents the cabinet from closing the order and renting the charger after a power outage due to disconnection.

1、Return the direction of POGOPIN to the cabinet when you return it.

2, in the return can find itself sweep the code of that store and machine, or around other search electricity on the machine can be.

3, after sweeping the code, align the chip hole inserted, the machine will identify the phone is connected to the rechargeable battery use time.

4, after the return of the 4 chips below the rechargeable battery aligned with the machine of the rechargeable battery, inserted into it can be returned successfully, back to the phone to pay the charging fee.

While Caller ranks fourth with a market share of 15.6%. While other charging treasure companies account for only 3.7 market share. It can be seen that its industry market concentration is high.

The impact of sharing economy on social economy

The impact of sharing economy on social economy is mainly reflected in the following four dimensions: individual, enterprise, government and social
First, at the individual level
From the perspective of supply side, different from the employment relationship under the traditional economic relations of production, sharing economy brings the employment mode of production labor liberalization, increases the working opportunities of laborers and increases their income.
Different from the transfer of ownership of new products under the traditional economic transaction mode, the temporary transfer of the right to use idle resources under the sharing economy mode reduces the idle rate of resources, accelerates the depreciation speed of assets and shorens the service life
From the perspective of demand side, the sharing economy effectively reduces the transaction costs of each link through the information search mechanism, pricing mechanism and credit increase mechanism, as well as the online operation mode and the establishment of standardized electronic contracts.
It opens up the price gap between goods and services in traditional industries, thus reducing the price level, improving the purchasing power of consumers, and increasing consumer demand.
In order to improve their own competitiveness and seize the market, the traditional economy will be more and faster to the direction of digital, platform transformation
Third, at the government level
First of all, the flexible and inclusive features of the sharing economy and easy market access conditions have provided more flexible jobs for workers, and played a prominent role in stabilizing employment and ensuring people’s livelihood.
Secondly, a large number of shared products flood into the market, supplementing the shortage of government public service supply and making the form of public service supply more diversified

(1) Public parking lot: Parking lot is one of the best places for social charging station, with convenient traffic and access. You can rent a parking space with the parking lot, or even a convenient corner location. And you can leave 2 charging spaces (because it is short-time charging. You don’t even need a special charging space. You can pay a certain fee according to the number of charging cars).

(2) Large shopping centers: the charging station placed here will certainly be welcomed by the shopping center. Charging people will incidentally buy goods (where to buy is to buy, just use the charging 10-20 minutes shopping). So that can achieve a win-win situation with the shopping center.

(3) Parking on the roadside: Parking in the city is getting more and more difficult. And many non-main roads are allowed to be used for temporary parking. Since the place occupied by the box type electric vehicle fast charging station is very small (less than 20㎡). There are many locations for the box type electric vehicle fast charging station to be placed, and it can be moved at any time as needed.

(4)Highway service area:A few box type electric vehicle fast charging stations are set up in the highway service area, and it can connect the surrounding cities. The number is small, but the significance is great, and it will greatly increase the confidence of electric vehicle users.

Is the anti-theft function of the shared rechargeable good?

The emergence of shared charging treasure to help people alleviate the problem of fast consumption of cell phone power and not lasting. The market outlook is very broad, and at the same time welcomed by many businesses. Many people seize this wedge opportunity to earn a lot of money. But in the process of operation also encountered equipment stolen things. Like this kind of thing should be how to solve it?

Nowadays, many shared charging cabinets are designed with card slots. Which will not pop up if the code is not swept. If consumers need to use the shared charging power. Then they need to deliver a deposit after scanning the code in order to use it.

In this case, even if the device is stolen. It is equivalent to selling a charging power, and the merchant will not lose money.

If the user forcibly removes the shared rechargeable battery by illegal means. The charging power will be shut down and locked up, making it impossible to charge.

Power supply system principle

The multi-functional shared charging system with solar panel mainly uses solar energy for power supply. When the sunlight is sufficient during the day. This system converts solar energy into electrical energy and stores it in the battery. And connects to the charging interface to supply power to the cabinet.

When there is sunlight shining on the solar cell, the potential difference is formed at both ends of the solar cell to realize the conversion of the absorbed light energy into electrical energy. And the electrical energy generated in this process store in the battery bank for use at any time. The charge/discharge controller can avoid generating overcharge and overdischarge of the battery and prolong the service life of the battery. The inverter completes the function of converting DC power into AC power. And when a user returns a rechargeable battery with insufficient power to the card slot. The battery performs intelligent fast charging of the rechargeable battery and displays charging information.

Services provided by the solar-powered shared charging cabinet

The multi-functional shared rechargeable battery cabinet with solar panel converts solar energy into electricity to provide charging service for rechargeable batteries. I solves the problem that the existing shared rechargeable batteries are placed indoors. Resulting in limited return time, and also makes full use of clean energy.

The multi-functional shared rechargeable battery cabinet with solar panels can installed near leisure and entertainment places such as railway stations. Shopping malls, bus stops, scenic spots, and pedestrian streets with a high flow of people. Combining intelligent shared rechargeable battery charging stations with solar energy. Making it convenient for users to take the shared rechargeable battery by sweeping the code for payment. And after use, people can return the rechargeable battery to other nearby outlets.

This cabinet uses solar energy for power supply, which is clean and environmentally friendly. The cabinet can set up outdoors. It is convenient for customers to return it at night. Which is convenient for users’ travel needs and highly practical.
