If you were to ask new energy vehicle owners what they are most concerned about, it is likely that more than half of them would say it's the range and charging speed. Indeed, with a total of 13.1 million new energy vehicles in 2022 and only 5.21 million charging piles, the issues of "slow charging" and "limited charging availability" have become the main contradictions. To address this, Juwan Technologies has introduced the "Phoenix Battery," which can charge from 0% to 80% in just 6 minutes, while also improving safety. So, what are the new technologies behind it?
The Phoenix Battery belongs to the XFC (e-Xtreme Fast Charge) battery series, and Juwan Technologies has provided several impressive data points. For example, it can quickly warm up from -20℃ to 25℃ in 5 minutes, supports charging at a rate of 8C (compared to the typical 1-1.5C), and has a high system energy density of 260Wh/kg. It features integrated designs for heat conduction, heating, buffering, and flame isolation, along with a large heat dissipation area to ensure rapid charging.
One of the four major technological highlights is addressing lithium plating and improving charging efficiency. Under the conditions of high-rate charging (8C rate, compared to the typical 1-1.5C in the market), the battery can undergo over 2000 cycles of charge and discharge. Additionally, Juwan Technologies has developed high-power liquid-cooled charging equipment, with a maximum power of 480kW, forming an overall solution from fast-charging batteries to fast-charging facilities.
Another highlight is the thermal and electrical management technology. According to Juwan Technologies, the entire battery system can achieve rapid cooling and heating within a controllable range. Even in cold winter conditions, it can be quickly heated from -20℃ to 25℃ in 5 minutes for fast warm-up. However, Juwan Technologies did not mention the energy consumption difference between fast warm-up and traditional solutions.
The Phoenix Battery adopts a multi-in-one cartridge structure, which means the battery cells are placed in compact cartridges that provide advantages such as heat conduction, heating, buffering, and flame isolation. This layout also improves the system's space utilization rate to 75%.
Furthermore, Juwan Technologies has developed an integrated solid-state switch matrix and control system, allowing the battery voltage to be freely adjusted. The XFC fast charging can be achieved across a voltage range of 300-1000V.
Although the installation of electric vehicle batteries has been rapidly increasing, the development of power batteries still faces many technological bottlenecks. Issues such as "seasonal differences" and "slow charging, limited availability" continue to trouble consumers. Technologically speaking, the Phoenix Battery does alleviate these problems to some extent.
