How to Maintain a Power Bank

1.Don’t wait until the battery is completely dead to recharge

Try to keep the battery power near the half full state. The smaller the range of charging and discharging, the better. So, usually the best use habit should be the use of 50% of the power after charging. Although the number of charging increased but compared to the total amount of light on the battery cell damage is lower.

2.the charging bank will also be afraid of cold and heat, should pay attention to the use of temperature

The operating temperature of the carp electric is 0-55°. When the external temperature is too low, the battery will not work stably and discharge is not sufficient. High temperatures, in turn, shorten the life of electronics, damage batteries and age certain plastics. These problems are concentrated in the winter and summer, but the border areas are also noteworthy for their extreme weather. In daily life, the car is a relatively closed environment, because the convection is poor. If the charging bank outside the state of charge and discharge is placed inside. It is easy to cause local high temperature and cause explosion

3.Avoid discharging while charging

The problem of discharging while charging mainly lies in the high load of the circuit board and the high temperature in a short time. Which affects the performance and safety. In addition, when we see that the nominal input value of the mobile power supply is 5V/1A, and the output value is 5V/2.1A, it is easy to make ends meet, and the internal parts of the charging bank are great damage.

4.waterproof.

To be clear, the power bank is not waterproof, so it is easy to make the product unusable once it is flooded. In daily life, because of wet weather, accidentally fall into the water, or use a wet cloth for cleaning, it is easy to let the mobile power supply water, resulting in leakage, short circuit or other failures.

Is the pricing of shared rechargeables reasonable

A few days ago, the topic of price increase of shared rechargeable treasure rushed to the hot search. The former price of 1 yuan an hour is gone. According to a survey by reporters, the price of most rechargeable batteries in urban areas is 3 yuan per hour. And most rechargeable batteries in business districts of 4 yuan per hour. With one place reaching 6 yuan per hour. However some netizens even reported that in some areas. It costs 10 yuan for an hour of shared rechargeable battery. The high price makes people cry “I can’t afford to use it”.

The price of rechargeable batteries is set by the merchants themselves, and the platform basically does not interfere

The reporter observed that rechargeable batteries can be seen in most of the restaurants. Beauty stores and barber stores that provide seats. And shared rechargeable battery cabinets can also be seen in roadside convenience stores. But the owner of a convenience store told us the rechargeable battery cabinet machine was placed there only to charge some electricity and earn some money every month. However, a beauty salon clerk said that the charging machine is placed in the store “mainly for the convenience of customers, not much money”.

What is the shared power exchange cabinet

Shared battery exchange cabinets are mainly use for battery equipment storage. Each cabinet stores one battery. And there is usually a display or QR code on the cabinet to prompt subsequent operations.

Battery rental is accomplish of controlling the switch of the cabinet door. While each cabinet comes with a charging device that charges the empty battery and stops when it is full. From charging to changing the battery. It greatly reduces the time to wait and allows riders to immediately depart with a full charge.

With the rapid development of the electric bicycle industry. While promoting the concept of energy saving and emission reduction. It is also an innovative change in service and consumer upgrade. Therefore, shared power exchange was born. Its existence not only meets people’s demand for power exchange. But also enables better circulation of batteries. And therefore gets spread rapidly in the express and take-away industries. In the future, shared power exchange cabinets will be the trend of development in the new energy era.

The correct use of mobile power supply

How does an electric vehicles carry the battery of a replacement cabinet?

The batteries inside the change cabinet are all lithium batteries with BMS protection plates. It is the standard size of the national regulations, so it is suitable for most of the lithium battery electric vehicles on the market.

If you do not meet the relevant V number of lithium electric vehicles we can dock through the conversion head. Lead-acid EVs or EVs with inappropriate battery sizes can retrofit and then switched into service.

At present, the technology of the power exchange cabinet is already relatively mature. For example. The power exchange cabinet produced by DuDu can realize single cabinet multi-model multi-v adaptive power exchange. And can also perform gridless power exchange.

How does an electric vehicles carry the battery of a replacement cabinet?

With the implementation of government policies related to electric vehicles and support for the power exchange model. The DUDU power exchange cabinet will continue to improve to apply to market development and user needs.

Advantages and disadvantages of sharing power banks

Advantages of sharing power banks

For consumers, there is no need to carry their own charging bank, and there are many places to borrow for temporary charging.
For businesses, the advantages of sharing power banks are as follows:
1. guests can choose free chargers, but also can choose to pay to share the charge bank . The shared charge bank can be take away, more convenient. In addition, the first 30 minutes of rental is the most free, emergency charging is fully enough. Giving guests more choices, service quality has been improved.

2.It greatly reduces the cost of chargers for businesses. Take the catering industry as an example, losing 3-8 chargers every month is the market average. According to a charger 20 yuan, a year’s charger loss has been close to 1000 yuan.

3.Renting a power bank can bring exposure (online) and customer flow (offline) to businesses. No matter renting or borrowing a power bank, they must walk into the store, and there is a certain chance of consumption (especially in beverage stores).

Disadvantages of sharing the power bank

The time and place of return should be considered. If it is lost accidentally, a certain amount of compensation should be paid and a certain credit deduction should be made.

How to use the shared power bank

1. When using the shared power bank, make sure the balance in the phone is enough to pay the 99 yuan deposit
2. Pay the deposit by scanning the code on wechat or Alipay. After scanning the code again, the shared charge bank will pop up automatically
3. Connect the phone with the Android, Apple and other data cables that come with the shared charging bank.
4. It is completely free for the first time when you use the shared power bank, but it will be charge at the specified price when you use it later.

What kind of electric vehicles is suitable for the power change cabinet

Since the new regulation of electric vehicles in 2020. Lithium batteries are gradually replacing lead-acid batteries as the main force of electric two-wheelers power batteries. And the number of replacement cabinets on the market is also surging with the number of lithium battery two-wheelers. Many people have the need to change the electricity.

The battery exchange cabinet is similar to a large shared rechargeable battery that comes with a lithium battery for the user to use. In an average of ten seconds. The user can change out the used-up battery and replace it with a fully charged one.

• Changing cabinet and battery must be matched, mismatched battery can not be charged and changed

Each change cabinet equipped with a certain number of batteries. Each battery bound to the cabinet, so only the battery that the change cabinet identifies itself bound to swallow in for charging. Any one of the batteries of the electric vehicles is not available to use the change cabinet.

Advantages of Shared Power Exchange Cabinet

1, the market demand is large: electric car crowd. Used for take-away electric vehicles reached millions of units, the market is extremely large.

2. Standardized management：Batteries have a designated shared area. T they need to be placed. All of which are almost free of indiscriminate parking and will not maliciously occupy public transportation.

3.Prevent loss: With the battery charging/exchange cabinet format. Battery in the compartment， It can not lost.

4.Significant income:Users use the frequency especially, such as delivery personnel, courier personnel, etc., the rental income is very substantial.

5.Application scenarios: use of electric vehicles such as food delivery, logistics couriers, etc.

The main users are take-away food delivery and logistics couriers who use electric vehicles, which are just in demand. Because they are busy in business so they use them more frequently, the shared batteries do solve their daily charging troubles.

Operating mode of shared charging bank

1. Mobile sharing in mobile mode
   As the name suggests, the power bank can be taken away and returned at another location. This model is similar to bike-sharing.
   The main profit points of this model are the rent of the charging bank itself, the advertising on the stand-alone equipment and the sale of supporting data lines. The nice thing about this model is,
   The charge bank is lent by the owner, so the user will be charged a deposit, similar to the deposit policy of shared bikes. But unlike shared bikes, the deposit of shared power banks is basically OK
   Cover the cost of a single charge bank, so the risk is relatively small.
2. Mobile sharing in fixed scenarios
   After the user borrows the charge bank, they still do activities in the neighborhood and return the original after using it. Compared with the first mode, this mode has less capital investment, and the risk is relatively small
   It’s relatively low. The purpose is to save the allocation of inter-regional charge bank, and the operating cost is smaller. Correspondingly, the main sources of income in this model are rent and sale data
   Line, advertising revenue is much lower than the first mode.
3. Fixed sharing in fixed scenarios
   This mode is generally reflected in the installation of a brand on the table outside the restaurant, coffee shop and so on. The charging bank and data line are integrated into one, that is, charging and using, without borrowing or supporting
   Pay a deposit, easy and quick. The advantages of this mode lie in dry, low wood formation and fast laying speed. As there is no need to lend the charge bank, the product depreciation is small and the risk is small.Its defect is that the profit point is single, basically only rental income.

Do I need a special connector to change the battery in the electrical cabinet?

Can be universal, change the electricity cabinet are unified using lithium batteries, different from the traditional lead-acid batteries. More durable. Only one fourth of the weight of lead-acid batteries more lightweight. The stability of these constituent materials itself is not too high. If the leakage of liquid or fire and other accidents. It compared to lithium batteries harm cause will be much higher. So the unified use of lithium batteries, the safety factor is higher. In order to use the electric car with safety with a long time. It is recommended that we should use lithium batteries.

Power distribution cabinet is the collective name of motor control center. And distribution cabinet used in the case of the load that can make the relatively dispersed and the circuit small. Also motor control center used in the case of the load that can make the concentrate and the circuit large. They distribute electrical energy from a circuit of the upper level distribution equipment to the nearest load. The equipment at this level should provide protection, monitoring and control for the load.
