On June 6, Greater Bay Technology Research, as the leader of extreme-fast battery(XFC) technology, held the "2023 Phoenix Battery Technology Conference" and officially released the new self-developed Phoenix battery.

It is reported that Phoenix battery integrates the latest scientific and technological innovation achievements of Greater Bay Technology Research in the fields of materials, electrochemistry, structure and control, so that electric vehicles have the ability to operate normally under all-weather (high and low temperature) conditions and achieve the maximum 8C speed charging  on different voltage platforms of 300 ~ 1000 volts. At the same time, it also has leading comprehensive advantages in terms of safety, service life, specific energy, endurance and cost, and is not afraid to compete with fuel vehicles. The advent of Phoenix battery will raise the technical level of power batteries and systems to a new stage.

Three major innovations lead the development of power battery technology and break through the limitations of climate and voltage platforms

With the increase of the penetration rate of electric vehicles, power battery technology has also entered a stage of rapid iteration and continuous breakthrough.

Although the path of power battery technology innovation is diversified, safety and charging speed are always the key core and pain points.

The Phoenix battery released this time integrates three technical highlights of high-efficiency thermal management, multi-in-one bomb structure, and bus voltage rise and fall switch matrix, which can greatly improve the safety and charging speed of the power battery, so that the operation of new energy electric vehicles and XFC  are not limited by environmental climate and voltage platform.

1. high performance thermal management technology, can ensure the full climate environment operation and XFC fast charging.

Based on the original research and development of lightweight extreme-high thermal conductivity low-dimensional materials, Phoenix battery uses the core heat exchange area to build a three-dimensional thermal management system, so that the heat exchange area is increased by 18 times compared with the traditional solution, the temperature control rate, efficiency and quality are improved by many times, and the ultra-fast cooling and heating are completed in a safe and controllable range. Even in winter, the battery temperature can rise from -20 °C to +25 ° C in 5 minutes , greatly improving the vehicle performance and user experience.

2. multi-in-one bomb structure technology, comprehensively improve the formation rate and safety protection ability.

In terms of the innovative design of the battery structure, Jubay Phoenix battery's unique superconducting heat, heating, buffering and fire insulation materials are integrated into a bomb bunker structure, placing the battery cell in a compact "bomb bunker", not only the thermal management of the battery is greatly improved, but also the impact resistance and penetration resistance are significantly enhanced, and the system volume utilization rate can be as high as 75%.

3. bus voltage switch matrix technology, support a variety of voltage platform models to achieve XFC fast charging.

Juwan Phoenix battery is equipped with an innovative highly integrated solid state switch matrix and intelligent control system, which can realize the free rise and fall of battery voltage, and can realize XFC  within the range of 300-1000 volts vehicle voltage platform.

For example, for the common 400 volt electrical architecture,Phoenix battery can still automatically achieve 800 volt XFC charging and 400 volt daily operation without changing the original architecture of the vehicle, thus breaking the constraint of the vehicle voltage platform on the application of the fast charging technology and greatly improving the applicability.

Five performance advantages, breaking through the bottleneck of power battery, power battery and system technology level reached a new high

Although the loading of new energy vehicle power batteries is growing rapidly, it cannot be ignored that the development of power batteries is still facing many technical bottlenecks.

Greater Bay Technology Research from materials, electrochemistry, structure and control and other aspects to promote technology research and development, through the three major technological innovations,Phoenix battery to achieve all-weather conditions of fast charging, ultra-long life, ultra-high safety, ultra-long life and lower maintenance costs, will effectively solve the new energy electric vehicle performance of winter and summer differences, travel "charging is difficult, slow" and other problems.

Accelerate the full adoption of electric vehicles.

1. all-weather operation and XFC fast charge.

 Based on the innovative XFC cell mass production products, with the support of three-dimensional thermal management and electrical management technology, the Phoenix battery can achieve 0-80% maximum speed charging under full climate conditions in only 6 minutes (8C), and ensure that the vehicle's driving range is not compromised under full climate (especially low temperature) conditions.

2.active/passive safety.

In terms of active safety, extreme thermal management greatly reduces the probability of thermal runaway and has early warning function. Through high-precision monitoring, estimation and millisecond precision control of each cell state, it effectively prevents the battery from overcharging, overcurrent and other safety hazards.

In terms of passive safety,Phoenix battery is equipped with ultra-high thermal conductivity and low-dimensional material thermal management unit, and also provides a powerful "bomb bunker" safety protection function for the battery cell, even if the thermal runaway of the battery cell occurs, it is contained in the "bomb bunker" and does not spread, and the ultra-fast cooling technology effectively takes away the heat, and does not fire for 48 hours in the battery system triggered thermal runaway experiment.

3. extreme-long life under the extreme-fast charging cycle.

The battery cell ofPhoenix battery has the characteristics of ultra-long life, and the thermal management system with extreme temperature control ensures that the battery always works at the most comfortable temperature and a very small temperature difference range, and the cycle life can be greatly improved up to 10 years or 800,000 kilometers.

4. High energy density supports long endurance.

The system is highly integrated design, the energy density can reach 260 Wh/kg, and the battery life can reach 1000 km on a single charge.

5. low-cost module maintenance brings better economy.

Based on the advanced modular design concept,Phoenix battery has a better system structure design, which makes the system maintenance more convenient, conducive to the cascade utilization of battery cells, and brings the lightweight and cost reduction of the whole pack of batteries.

Greater Bay Technology research said that Phoenix battery will be mass-produced in Greater Bay Technology research (Nansha) energy storage device and system production base next year, and is expected to be installed at the end of next year.With continuous technological innovation and breakthrough,Phoenix battery strengthens the applicability of electric vehicles and promotes the development of electric vehicles in a more efficient, safer and more convenient direction by comprehensively improving the charging speed, endurance, service life and safety guarantee performance of power batteries under all-weather and full-voltage platforms. Accelerate the popularization of electric vehicles.
