According to statistics, the number of electric motorcycles in the market has reached about 350 million units, mainly two-wheeler and three-wheelers.
As a representative of green travel, electric two-wheeled vehicles have developed rapidly with the rapid development of the industry, and at the same time, they not only promote the concept of energy conservation and emission reduction, but also serve innovation and consumption upgrading.
1. Features of battery swapping service
Due to the large number of applications of lithium battery, the current battery swap mode has been widely used, and the major battery car sales points in the city have set up battery swap cabinets to facilitate take-out, and express personnel can replace the battery at any time.
The battery of the battery swapping cabinet needs to have various sensors such as power detection, smoke detection, temperature detection, etc., and has the functions of positioning and signal transmission cloud center.
Various sensing data are read in the battery swapping cabinet via the BMS protocol. In a variety of outdoor environments, overvoltage reliability design is particularly necessary, including 12v 100ah lithium ion batteries and BMS control boards.
2. Constraints of electric motorcycles
It is used to meet the surge protection of the DC power supply interface, and select the appropriate protection current device according to the environment in which the power supply is located.
The use of multi-channel integrated device protection can ensure signal integrity at the same time, can filter out noise, pass the electrostatic test. In order to earn more revenue, delivery riders must deliver more orders. The more orders, the longer the mileage and ride time.
According to public data, the average daily mileage of delivery riders is as high as 120km, and the average ride time is as long as 12.5h. In order for riders to achieve longer mileage, in addition to physical strength, the power of electric motorcycles must also keep up, but there are many pain points to this.
- Limited battery capacity
At present, the endurance of mainstream electric two-wheelers and three-wheelers has been greatly improved, and they generally run more than 50km on a full charge, but they still cannot meet the needs of riders for a day. When the temperature drops, especially in winter, the battery life of an electric vehicle will drop significantly.
It takes at least 3 to 3 hours to charge a 12 volt 200ah lithium battery and at least 3 to 5 hours to fully charge a battery, resulting in a situation where there is an order but it cannot be delivered.
3. Battery charging is limited by location
Although public charging stations can charge, the number of riders is too large to meet their daily charging needs. Neither the battery capacity nor the charging place is sufficient, and some riders can only be equipped with two or three batteries to charge alternately.
However, the purchase of batteries not only increases the cost, but also squeezes space on electric motorcycles, causing problems to work. Many riders are not willing to do this.
Overall, one of the biggest pain points for today's delivery riders is range anxiety caused by inconvenient charging. In this situation, the replacement of electric vehicle battery swapping cabinets has alleviated the anxiety of many riders.
Like the use of shared power banks, the operation of the two-wheeled vehicle battery swapping cabinet is also very convenient. The rider only needs to scan the code to open the cabinet, take out the battery and install it, and it only takes three or four minutes to complete the whole operation.
It can be said that the two-wheeler battery swap service can help riders improve work efficiency and increase delivery mileage through "replacement charging", and alleviate range anxiety.
4. The intelligent battery swap project solves the battery life
Get rid of the troubles of difficult charging, expensive charging and long charging times. The intelligent battery swap project focuses on the rider's battery swap and solves the rider's battery life problems.
Solid-state battery swapping uses solid-state batteries, and lays intelligent battery swapping cabinets to provide safer and more convenient one-stop battery swap services for the majority of riders.
Starting from the battery, the use of new solid state batteries is not easy to catch fire and explosion, and fundamentally ensures the safety of use. Improve security Introducing advanced solid state battery technology to improve the performance and safety of non-motor vehicle batteries and reduce the risk of traffic accidents caused by battery problems.
In the case of heating and puncture during charging, there is no internal ignition or detonation. In case of cutting during the power-on process, it can still work when the power is on.
5. The industry is constantly evolving
Electric two-wheelers have undergone years of adjustment, and major brands have completed the independent research and development from passive adaptation to standards to active development under the standardized framework system.
Among them, the iterative upgrading and evolution of energy technology has become the core of driving the upper limit of category performance and user experience.
The policy-driven trade-in outlet is gradually coming to an end, and the industry is about to usher in a critical moment, and behind the coexistence of opportunities and pressures, product evolution is expected to become the core of determining the upper limit of the industry.
Although two-wheeled electric vehicles provide great convenience for citizens to travel, their non-standard use has also brought a series of problems to people's daily lives. For example, grabbing lanes with motor vehicles, parking indiscriminately, blocking sidewalks, causing fires, etc.
The battery swapping cabinet is the main hardware of the whole system, and the interior is mainly composed of the control host, storage board and many monitoring and protection modules.
Due to the storage of a large number of batteries inside the battery swapping cabinet, charging will cause the temperature inside the box to rise, which is very prone to accidents.
In order to protect the safe and stable operation of the battery swapping cabinet, it is equipped with a lot of protective monitoring equipment. Such as the installation of water immersion, smoke sensors, temperature and humidity sensors, fans, lightning protection devices, fire protection devices, voltage detection modules, current detection modules, etc.
When there is leakage, short circuit and overload in the battery swapping cabinet, it will automatically cut off power protection, and notify the background administrator to protect the safety of charging and electricity from all aspects.
6. Conclusion
The popularity of the electric bicycle track is rising, and the battery swap market is also booming, but problems such as the layout density of the battery swap station, inconsistent battery specifications of the vehicle model, and the high cost still need to be solved.
