Beijing March, heroes talk | Sunwanda Power flash charging battery leads super charging advanced technology and has the right to speak

After more than ten years of development, China's new energy vehicle industry has gradually achieved considerable and steady development, driven by the global dual-carbon strategy and sustainable development goals. The momentum of industrial development is rapid. China's power battery industry has gradually gone from learning, catching up, and running with the world to leading the world.

As the industry enters a new stage of development, technological and business innovation becomes more active, and international competition becomes more intense. How to further consolidate and expand development advantages, enhance corporate and industrial competitiveness, and expand growth space and value boundaries? Promoting industrial ecology and global win-win cooperation is a topic of common concern and thinking for all new energy people.

On March 17, Sunwoda Power was invited to attend the China Electric Vehicles Conference of 100 People. Li Yangxing, Vice President of R&D of Sunwoda Power, was invited to attend the power battery sub-forum of the 100 People Conference and work with power battery industry leaders, experts and scholars. Share Sunwoda Power's world-leading flash charging battery technology and integrated optical storage, charging and inspection ecology, use innovative technologies to lead the industry direction, and empower the green economy, low-carbon and sustainable development.

The shift in market demand for “moderate battery life and super fast charging” will bring about a blowout development of supercharging

In 2023, global new energy vehicle sales will reach nearly 13 million, of which China’s new The proportion of energy vehicles is as high as 7.27 million; global lithium battery shipments in 2023 will be nearly 1,203Gwh, of which China's shipments will be 887Gwh, accounting for nearly 74%. China's new energy vehicle market continues to flourish, benefiting from all China's new energy people years of unremitting efforts.

At the forum, Li Yangxing said that under the new development pattern, the popularization of overcharging and the integrated application of optical, storage, charging, and inspection are the new development directions of the industry. While increasing charging speed and achieving efficient energy utilization, these innovative measures will push the new energy vehicle market towards a more intelligent, efficient and sustainable direction.

Currently, benefiting from the steady improvement of the domestic new energy market and product competitiveness, 2023 will become the first year for the launch of EV overcharging, and 2024 will also be regarded as the first year for the implementation of fast charging standards. Overcharging is expected The market share of automobiles will increase from 3% in 2023 to 52.5% in 2030.

In the booming market environment, the construction of high-power charging piles has been strongly promoted by policies and is expected to become the main construction subject of public charging piles in the future. National policies are continuously strengthening the layout of supercharging networks to meet the growing charging demand.

Li Yangxing believes that user demand for new energy vehicles is also changing. From the initial pursuit of "long battery life" to now more emphasis on "moderate battery life and super fast charging", this change undoubtedly provides a huge market space for the development of supercharging technology. 2024 is expected to be the first year of the explosion of 800V pure electric models, and BEVs priced at more than 200,000 will become the focus of market competition.

Sunwanda Power’s three major independent innovative designs for flash charging batteries lead the industry’s advanced technology discourse

Sunwanda Power, driven by the two wheels of market demand and technical engineering, is planning to lay out ultra-fast charging technology in 2022. , in 2023, focused on creating and releasing the world's first mass-produced product with long battery life, ultra-fast charging, extremely fast energy replenishment, safety and durability, and high value preservation - flash charging battery. Adopting 4C NCM super fast charging, it supports electric vehicles to easily last 1,000 kilometers and can be charged to 80% SOC in 10 minutes, making charging as fast as refueling.

Li Yangxing believes that technology facing the world requires continuous innovation from the source and bottom. Sunwoda’s flagship product, flash charging battery, has applied a lot of technological innovation. He introduced that the flash charging battery adopts key technologies such as independently designed flash charging high-conductivity network material technology, independently designed high-safety medium-nickel cathode, and independently developed new high-conductivity electrolyte, which solves the problem of short cruising range and slow charging speed of new energy vehicles. , safety performance and other difficult issues. In addition, the full life cycle adaptive overcharging strategy, high-precision coating and lamination technology make "flash charging batteries" safer and more reliable.

Based on the precise insight into the pain points of northern vehicle users using cars in winter, Sunwanda Power also launched the LFP 600A flash charging battery product in 2023. Through materials (high-energy and high-power chemical systems), electrodes (high-speed electrode technology) and structures (Low internal resistance technology) Three major technological innovations, thereby eliminating user anxiety about charging and low-temperature mileage in winter.

At present, the charging capacity and energy density of flash charging batteries continue to iterate, and they are at the leading level in the industry in terms of cell performance, cost, and mass production delivery. It is the leading brand of super-charging batteries in the world. In addition, Sunwoda Power continues to develop products with higher magnification rates. The development of 5C~6C flash charging batteries is smooth, and its technological progress is ahead of its peers. It has lower internal resistance and better heat dissipation performance, giving it a first-mover advantage in the industry!

Integrated upgrade of optical storage, charging and inspection, empowering the integrated development of new energy vehicles and energy storage

With the popularization of electric vehicles and the development of new energy power generation technology, people are more concerned about energy The needs and utilization methods have also changed. As a new industrial model, optical storage charging and inspection combines new energy vehicle batteries with energy storage batteries to form a new energy ecosystem.

Li Yangxing introduced that the empowerment model integrating photovoltaic, storage, charging and inspection achieves flexible dispatch and efficient utilization of energy. New energy vehicle batteries and energy storage batteries are connected through an intelligent management system to form a unified energy network. The battery can flexibly switch between charging, discharging and energy storage according to energy demand and supply conditions.

In addition, the integrated light storage, charging and inspection model promotes the development of new energy vehicles and renewable energy. Incorporating the power battery of electric vehicles into the energy system can realize the energy feedback and energy storage functions of electric vehicles, and improve the cruising range and usage flexibility of new energy vehicles. At the same time, energy storage batteries are used in renewable energy systems to solve the instability and intermittency of renewable energy and achieve stable supply and efficient utilization of energy.

Summary:

Looking to the future, Sunwanda Power will unswervingly delve into the field of supercharging technology, commit to continuous innovation and technological breakthroughs, and contribute to the prosperity and development of the global new energy automobile industry. Inject more power. At the same time, Sunwoda Power will actively work with upstream and downstream partners in the industry chain to jointly promote the high-quality development of China's new energy vehicle industry and contribute more to the realization of global green travel goals.
