Frontline | Sunwoda Electric Vehicle Battery Made an Appearance at the Shanghai Auto Show and Unveiled Smart Battery Cell 2.0

On April 23rd, the 21st Shanghai International Automobile Industry Exhibition officially kicked off. Sunwoda Electric Vehicle Battery Co., Ltd. (Sunwoda EVB) showcased innovative solutions covering nine scenarios, including pure - electric, hybrid, commercial vehicles, and low - altitude flight.

In the hybrid market, thanks to the ultra - high power performance of 60C fast charging and 70C fast discharging and the ability to withstand extremely cold temperatures of - 30°C, the installed capacity of Sunwoda EVB's HEV batteries has exceeded 1.5 million units.

The core products for range - extended and plug - in hybrid models, the Xin Xingyao/Xin Xingchi series, can achieve cold start at - 35°C and maintain over 90% of the range at - 20°C while ensuring a charging capacity of 2C - 6C and a maximum pure - electric range of over 500 km. At the same time, these products have passed six extreme safety tests, such as high - temperature needle penetration of the battery cell and 12 - meter high - altitude drop, and support a long - term warranty of 10 years/over 300,000 km.

In the pure - electric market, Sunwoda EVB's 3.0 fast - charging battery made another appearance. With a peak charging rate of 6C, it can achieve an energy - replenishment efficiency of "1 km per second". The low - temperature superconducting electrolyte and 3D liquid - cooling thermal management technology have solved the problem of performance degradation in extremely cold environments, increasing the charging efficiency at - 20°C to 90% of that at room temperature.

On this basis, Sunwoda EVB's ultra - fast charging products with a charging rate of 8 - 10C and above will soon be launched, further reducing the energy - replenishment time from 10% to 80% SOC to 7 minutes, making "charging more convenient than refueling".

In addition, Sunwoda EVB also launched an intelligent lithium - plating boundary monitoring system to ensure that ultra - fast charging does not damage the battery throughout its life cycle. Combined with the high - energy - density lithium iron phosphate version of 450Wh/L and the 1000 - km range of the ternary version, it constructs a complete closed - loop from leading parameters to user value. Currently, this technology has been installed in high - end models of several leading automobile manufacturers.

Sunwoda EVB's layout strategy of "pure - electric on one hand and hybrid on the other" effectively realizes the coordinated development of technologies. It not only shortens the R & D cycle but also promotes the hybrid models to enter a new stage of "ultra - fast charging + long range".

In the commercial vehicle market, Sunwoda EVB has developed a commercial vehicle battery with a super - high power charging capacity of 1.4MW, which can achieve rapid energy replenishment in 15 minutes, increasing the transportation efficiency by 400%. Through a long - life material system and intelligent strategies, the battery's cycle life has exceeded 5000 times, precisely matching the 8 - year/2 - million - km operation cycle.

Its modular CTP platform supports the adaptation of 85% of commercial vehicle models. The three - dimensional directional pressure - relief technology realizes cell - level thermal runaway protection. Combined with a smart operation and maintenance network covering 32 cities and battery passport carbon footprint tracking, it constructs a full - life - cycle closed - loop of "ultra - fast charging + battery swapping + cascade utilization".

In addition, Sunwoda EVB has reached in - depth cooperation with leading enterprises in the flight industry and demonstrated its aviation power battery technology matrix: the energy density of the semi - solid battery has exceeded 400Wh/kg, passing the 200°C hot - box and puncture tests; the large - cylindrical battery supports 4C rapid energy replenishment and high - altitude compression resistance, and is equipped with a three - dimensional thermal spread blocking system.

At the exhibition stand, a vertical take - off and landing composite wing drone system equipped with Sunwoda's low - altitude aircraft battery was unveiled. In the future, Sunwoda EVB will also cooperate with customers to layout a "ultra - fast charging + energy storage" composite energy network and an airspace intelligent management platform, promoting the transition of eVTOL and logistics drones from single - point breakthroughs to large - scale commercial use and empowering the trillion - level low - altitude economy.

It is worth noting that Sunwoda EVB also exhibited its 2.0 intelligent battery cell products at this auto show. In the 2024 Beijing Auto Show, it released the first - generation "Dianjing" intelligent battery cell sensor, which achieved technological advantages such as independent management of single battery cells, multi - dimensional data collection, and wireless communication.

The newly launched 2.0 intelligent battery cell this year is an upgrade based on the "Dianjing" intelligent battery cell sensor. By integrating multi - dimensional intelligent sensors on a single battery cell, in addition to the traditional BMS current, voltage, and temperature detection, it can obtain new parameters such as the internal air pressure of the battery cell, shell deformation, and electrochemical impedance. In practical scenarios, it has four major highlights: better safety early warning, longer service life, higher SOX accuracy, and a battery - cell - level battery passport.

The 2.0 intelligent battery cell realizes the "transparent operation" of the battery cell. By analyzing the multi - dimensional parameters affecting the safety of the battery cell throughout its life cycle and combining with Sunwoda EVB's self - developed BMS algorithm, it ensures the safety, performance, and life of the battery cell during its entire life cycle from the user's perspective, and ensures the controllability of data throughout the life cycle through the battery - cell - level battery passport.
