VREMT Engineers Connect with Users on EV Charging

2023-06-06 | VREMT

From the perspective of C-end users, empower users' lives with products. VREMT, deeply involved in the development of new energy vehicle pack, battery, e-drive and OBC for decades, has always had a close relationship with users. Recently, in order to get closer to users' life and further understand users' needs, Wang Cheng, the product director of charging facilities in the Automotive Electronics Business Division of VREMT, was invited to participate in ZEEKR special Z-talk in Shenzhen, which started an in-depth exchange about efficient EV charging between engineers and users.

C-end Users' Charging Needs and Pain Points on Electric Vehicles

Can the battery pack capacity and vehicle driving distance meet the daily needs? Are the supporting energy replenishment facilities perfect? Is the energy replenishment efficiency and experience efficient and convenient? At the beginning of the activity, Wang Cheng interacted with users on some considerations that users often face when purchasing battery electric vehicles, which helps him understand the current pain points of users about EV charging and also narrows the distance with users.

During the on-site communication, users spoke freely and shared their views on battery electric vehicles and actual car usage experience. Some users said that the current battery capacity and driving distance of battery electric vehicles can meet the travel needs in most cases. What really affects the travel distance and experience is actually the energy replenishment efficiency and experience. Because the product quality of most charging stations and chargers on the market is different, it is difficult to guarantee the energy replenishment efficiency.

VREMT Supercharger Solution

In view of the problem of energy replenishment efficiency that users care about, Wang Cheng also communicated with users by taking the supercharging station built by VREMT and ZEEKR as an example. At present, the charger used in the supercharging station is the world's first mass-produced 600 kW liquid-cooled supercharger from VREMT. At the same voltage platform, the maximum output current of VREMT supercharger can reach 650 A, and the charging efficiency is more than 2 times that of DC fast charger in the market. After listening to Wang Cheng's introduction, the users also understood his saying "Not all chargers are superchargers".

VREMT Supercharging 2.0 Era

Say goodbye to the charging anxiety and optimize the charging experience: VREMT continuously improves the liquid-cooled technology, increases the voltage and current of the supercharger, and increases the charging power, achieving the maximum charging power of 600 kW at the terminal, which can realize driving of 300 km just with 5 min charging.

Leading technology, faster step: VREMT is the only enterprise in China that realizes 600 kW supercharging technology. The charging speed is constantly refreshed, and it only takes one song’s time to complete energy replenishment.

Mass production in advance, even better: VREMT 600 kW ultra-high power high-speed charger has been officially mass-produced and can be put into market quickly. The large-scale layout has improved the popularizing rate of chargers, making charging as convenient and fast as refueling.

Intelligent scheduling, better scheme: it has intelligent power scheduling at the charging station level, and power sharing and capacity expansion technology, with a "power pool" at the charging station built, which can meet the maximum charging demand of vehicles in adjacent parking spaces at the same time.

Lightweight and Convenient: Liquid-cooled Cable of VREMT Superchargers

At the activity scene, the daily charging experience has also become a major concern for users. From the perspective of users, charging efficiency is the most critical but also the most basic attribute of chargers. In particular, female car owners at the scene said that many charging guns are cumbersome and heavy when they charging outside, which is inconvenient for them. However, the outer diameter of the liquid-cooled cable of VREMT supercharger is 24 mm, and the weight of the cable is only 1/2 that of the conventional cable, enabling female car owners to operate with one hand and charge more easily. In addition, the supercharger with liquid-cooled design can not only provide better safety protection, but also make the running noise as low as 55 dB, so that the owner can avoid noise pollution when charging and enjoy the journey with a better mood.

VREMT Supercharger: Plug and Charge, Hassle-free Charging

Many users participating in this activity also have a good knowledge reserve for battery electric vehicles and charging technology. Therefore, at the activity scene, they had a deep discussion with Wang Cheng on their most interested issue - the function of "plug and charge, hassle-free charging" of VREMT supercharger. The supercharger realizes "plug and charge, hassle-free charging", which means that users can directly handle the payment in the backstage without swiping card or scanning code at the beginning or the end. This greatly improves the usability and fluency of the whole charging experience and makes the charging process "delightful".

Wang Cheng explained to the user: "In addition to supercharger, VREMT is also an important partner of the ZEEKR core products for new energy vehicle pack, battery, e-drive and OBC. Therefore, thanks to the perfect independent R&D ability, we can better adapt to the needs of our whole vehicle at the beginning of product design, and finally skillfully realize the linkage of vehicle and pile, and realize plug and charge, hassle-free charging. This kind of independent R&D ability and suitability is also unavailable to most charging facility manufacturers, because we have been focusing on the whole vehicle from the beginning."

VREMT Future Electric Vehicle Charging Product Planning

At the end of the activity, Wang Cheng also looked forward to the future of charging and energy replenishment with users. After learning that users hope that the energy replenishment efficiency and convenient experience can be further improved in future, he and users simply thoroughly foretasted VREMT's future product planning. In VREMT's next generation of supercharging products, the energy replenishment efficiency and experience will be continuously upgraded to bring users a more efficient, convenient, and comfortable car charging experience. This also makes users look forward to the future of charging and energy replenishment, hoping to have in-depth exchanges with VREMT engineers again.

VREMT

This activity in Shenzhen not only enabled users to further understand the product advantages of VREMT supercharger, but also narrowed the distance between VREMT engineers and users, and let VREMT further understand the real needs of users about EV charging. In future, VREMT will continue strengthening the communication between engineers and users, take users' needs as the guide, and take technological innovation as the driving force to bring users a more scientific, intelligent and convenient product experience!
