Mobile Charging Power Banks for You

Range Anxiety in Electric Cars? Mobile Charging Power Banks for You.

☆Range anxiety is a persistent concern for most electric vehicle (EV) owners. Whether your EV has a range of 500km or 1300km, this worry remains difficult to alleviate. Ultimately, this mindset stems from concerns about the convenience of recharging.

☆Recently, a video was uploaded on Bilibili by a content creator who shared his experience of almost being stranded in a snow-covered mountain while driving a Tesla in the United States. Here’s the sequence of events: with the vehicle fully charged, he planned a trip to the mountains, expecting the electric car’s range to be more than enough for a round trip. However, on the return journey, the road was blocked by police due to extremely cold weather conditions, forcing him to turn on the heater and increase energy consumption. What was initially a 100-mile range was reduced to less than 30 miles when he was ready to head back. Despite rushing to a charging station 20 miles away, the car still broke down, leading to a call for roadside assistance.

☆Since then, a diesel generator has become his indispensable companion. “Although it only provides 5 miles of range per hour, it gives me enough peace of mind,” he said.

☆In the United States, inadequate infrastructure layout and sparse population density contribute to range anxiety for EV owners. Looking at the charging facilities for new energy vehicles (NEVs) in China, there is a well-established charging network, but in reality, users often encounter long queues for charging and find charging spots occupied by conventional vehicles. During holidays, reports about difficulties in charging NEVs often emerge. Especially during extremely cold weather, experiences similar to almost being stranded in snow-covered mountains are highly likely to occur.

☆With the increasing number and penetration rate of EVs, not to mention holidays, even ordinary rest days make it challenging to find available charging spots. Although the infrastructure for charging stations is continuously improving in China, the pace of development still lags behind the growth of EVs. Furthermore, there is always a probability of malfunctioning charging stations, despite previous infrastructure development efforts.

☆As of November 2023, the ratio of charging spots to vehicles has reached 1.78:1, but it is still far from the ideal ratio of 1:1. These statistics also include privately owned charging stations. However, since many users can only use public stations, the actual ratio is likely higher.

☆NIO’s battery swap model has partially alleviated the pressure of recharging. However, some users may still have concerns about the inconsistent quality of batteries, so this model still raises concerns for some users.

☆In addition, mobile EV charging power banks offer another appropriate solution. Recently, Jiaxing, China has introduced a service providing mobile EV charging power banks. These power banks can be scanned and automatically dispatched to the owner’s vehicle. With a power output close to 100kW, they can provide 15kWh in 10 minutes, adding 75km of range, which is faster than typical DC fast charging stations.

☆Actually, a British company released a similar product long ago, but it required the owner to carry a bulky power bank in the trunk. What’s more surprising is that this type of power bank still requires a charging station for recharging.

☆The core of current mobile EV charging power banks lies in their automatic navigation feature, eliminating the need for manual intervention as they move autonomously to the vehicle to provide recharging services. Some companies have applied experiences similar to hotel service robots to mobile EV charging power banks, allowing them to automatically avoid obstacles, and recognize parking spaces, and license plate numbers without human intervention.

☆Some mobile EV charging power banks can even automatically plug and unplug the charging cable, making them more intelligent. One interesting mobile charging power bank from a charging station company not only meets basic recharging needs but also automatically reserves parking spots for owners. After scanning a QR code for reservation, this mobile charging power bank can automatically reserve a parking spot for the owner and begin charging when the vehicle arrives. However, parking fees start accumulating as soon as the power bank secures a parking spot.

☆Despite the apparent potential and convenience of mobile EV charging power banks, they still face technological barriers, and not all manufacturers can develop them. For instance, can mobile EV charging power banks accurately avoid obstacles and find vehicles? Can they accurately identify the charging port on the vehicle? Most importantly, charging station companies need to coordinate charging protocols with automotive manufacturers.

☆Furthermore, the weight of EVs themselves can reach several hundred kilograms, requiring mobile EV charging power banks to have sufficient service capabilities. Consequently, they also consume a considerable amount of energy.

☆Finally, mobile EV charging power banks require battery storage for electricity. However, these batteries are liquid-state power batteries, and their safety remains to be assessed. If one day these power banks are distributed in the parking lots of major shopping malls and service areas, these safety concerns cannot be underestimated.

☆In conclusion, while mobile EV charging power banks seem to have unlimited potential and great convenience, their prospects are still unclear. Currently, Wenzhou Bluesky provides EV mobile charging stations that need to be connected to the power grid. In the future, they will continue to keep pace with the times and develop mobile EV charging power banks independently. Stay tuned!
