At the first high-level forum of the China EV100, Xu Daquan, Executive Vice President of Bosch (China) Investment Co., Ltd. (hereinafter referred to as Bosch), said that the electrification of automobiles will still take time, and my country's power batteries urgently need to overcome technical bottlenecks and achieve standardized production of power batteries.
Xu Daquan stated that in the past few years, Bosch has invested 3 billion yuan annually in automotive research and development, primarily in battery research and development.
Currently, the energy density of batteries and electric motors combined is insufficient to replace engines. Taking an electric vehicle with a specific energy of 200 watt-hours per kilogram as an example, and considering all heat consumption, gasoline has a specific energy density of nearly 2000 watt-hours per kilogram—a tenfold difference. This demonstrates that electric vehicles still have a long way to go compared to traditional vehicles.
Speaking about the current state of power batteries in China, Xu Daquan said that my country's lithium battery technology still lags behind that of Japanese and Korean companies, and there are still many technical challenges to overcome. Bosch, as one of the battery suppliers, is also actively investing in related research and development.
Xu Daquan stated that the key to power batteries lies in the battery pack, namely battery group management. Currently, 54% of the batteries used by OEMs in my country come from their own subsidiaries or joint ventures with battery companies. However, the battery manufacturing processes of each manufacturer are different, which poses a challenge to suppliers.
Finally, Xu Daquan pointed out that how to achieve standardized and regulated production of power batteries in the future, and how to realize the electrification of automobiles, requires all companies in the industry chain to jointly explore solutions.
