Analyze best battery swap station system and existing problems

With the enhancement of environmental awareness and the transformation of energy structure, electric two-wheelers and three-wheelers have received extensive attention and promotion as a clean and sustainable mode of transportation.

However, the problem of limited cruising range has become an important factor limiting its popularity. To solve this problem, the best battery swap station system becomes a viable solution, providing the energy needed to keep driving by quickly replacing the battery.

1. The basic principle of the best battery swap station system

The best battery swap station system is a process of charging and swapping batteries by quickly replacing them. In the process of charging and swapping, it mainly involves the charging and discharging of the battery swapping station.

Charging refers to replenishing the stored energy in the 12v 100ah lithium ion batteries through an external power source, so that its energy storage capacity can be restored. During the charging process, it is necessary to pay attention to the control of parameters such as charging current, charging voltage and charging time to ensure the safety and efficiency of the charging process.

Discharge refers to the release of energy stored in the battery to power an electric vehicle. During the discharge process, the discharge current and discharge time need to be controlled to ensure that the battery can provide sufficient power supply.

2. Charging and swapping technology for best battery swap station system

At present, the charging and swapping technologies of the best battery swap station system mainly include the following:

• DC fast charging

Fast charging is achieved by feeding power directly into the EV battery via a DC charging device. This technology has the advantage of fast charging speed and is suitable for scenarios that require fast charging in a short period of time.

• Constant current and voltage charging

By controlling the size of the charging current and charging voltage, the 12 volt 200ah lithium battery can be charged with a stable current and voltage to improve the charging efficiency and protect the battery.

3. Four major components of best battery swap station system

The structure of the battery swap station can be divided into four parts: battery swap system, charging system, battery swap platform and control system.

• Battery swapping system

The function of the battery swapping system is to remove the battery loss from the electric two-wheeler and tricycle and transport it to the battery swapping station.

And get the fully charged battery from the battery swapping station and transport it to the battery swapping platform to complete the battery exchange work. The battery swapping platform is one of the most important equipment in the battery swapping system.

• Charging system

The main equipment of the charging system in the battery swapping station is the charging compartment, which charges the replaced battery in the form of centralized charging and AC slow charging.

In the charging system, the battery box design technology has high requirements for environmental control, safety protection, locking and fast unlocking technology.

• Battery swapping platform

The battery swapping platform includes a battery swapping app and a monitoring platform for locating and monitoring the battery condition. In the current solution, one of the NFC functions can also be used. Tycorun's self-developed platform has accumulated a lot of experience.

• Control system

The control system is responsible for communicating with the customer's equipment, as well as with the coordination equipment of the battery swap station.

In simple terms, the control system receives a request for a battery swap from a client device and selects one of several battery swapping platforms to perform the swap operation. The control system involves the identification of electric vehicles. 

4. Battery swap station system demand analysis

In order to meet the demand for charging and swapping, the battery swap station needs to have the following characteristics:

Rapid: The best battery swap station system needs to have fast and efficient charging and swapping capabilities to provide the convenience of battery replacement for electric motorcycles in a short time.

Safety: The charging and swapping process requires strict control of various parameters to ensure the safety of the charging and swapping process. Prevent problems such as thermal runaway, overcharging or overdischarging the battery.

5. Problems with the best battery swap station system

• High investment costs

Compared to the investment in charging piles, the construction cost of a single battery swap station plus the cost of backup batteries is higher. What is more difficult is that, in order to support the normal operation of battery swap vehicles, it is often necessary to establish multiple battery swap stations in a pilot area to form a battery swap network.

• Uniform standardization 

The 12v lithium ion battery pack of different brands and models have a low degree of standardization and large size differences, making it difficult to share battery swap stations.

Due to the objective reasons of different car companies and different models, there is no unified battery standard, which limits the development of battery swap mode to a certain extent.

• Low penetration rate of battery swapping vehicles  

First of all, there are few battery swap vehicles, and the utilization efficiency of battery swap stations is low, which increases the payback period. The second is that there are few battery swap models.

And if you want to promote battery swap mode on a large scale, you need to develop battery swap mode from the time of vehicle design, and you need to have a certain scale of vehicle ownership.

6. Challenges for battery swap station systems

The battery swapping station can support fast charging technology to improve charging efficiency and reduce user wait times. However, there are some challenges associated with fast charging technology.

Fast charging can cause battery overheating and wear and tear, requiring effective heat dissipation and temperature control measures. High-power charging places higher demands on best battery swap station systems and power distribution equipment, and factors such as power supply capacity and cable capacity need to be considered.

Therefore, when designing best battery swap station systems, these challenges need to be overcome to ensure the safety and reliability of fast charging technology.

• Power supply stability and capacity requirements

The best battery swap station system needs to have a stable power supply and sufficient capacity to meet the needs of charging and swapping equipment.

However, battery swapping stations usually have a large number of owners charging or replacing batteries at the same time during peak periods, which poses a challenge to stability and capacity.

When designing a power supply system, it is necessary to carry out load analysis and capacity calculation, and reasonably plan the power supply capacity and cable capacity to ensure that the power supply system can stably meet demand during peak periods.

• Charging and swapping equipment layout and space constraints

Battery swap stations are usually laid out in a limited space, so the reasonable layout and space utilization of charging and swapping equipment has become a challenge.

Factors such as the size, ventilation requirements, and safety spacing of charging and swapping equipment need to be taken into account to ensure the safe interval between the devices and ventilation and heat dissipation conditions.

In addition, there is also a need to leave enough space for operation and maintenance to ensure a smooth charging and swapping process.

7. Conclusion

In terms of the principle of charging and swapping, the use of fast charging technology can improve charging efficiency and user experience, but it needs to solve the problem of battery capacity loss and overheating.

The best battery swap station system needs to have a stable power supply and sufficient capacity, and at the same time consider the equipment layout and space constraints to ensure the stability of the power supply system and the safety of the charging and swapping equipment.
