[News] BYD Amasses 13,000 EV Patents, 15 Times More Than Tesla
Source to Carfun, in the past two decades, Chinese electric vehicle (EV) manufacturer BYD has been relentlessly pursuing patents for EV technology, amassing a staggering 13,000 patent applications, a figure more than 15 times greater than Tesla’s modest 863 patents. The stark contrast primarily boils down to one critical component: batteries. BYD not only produces its own batteries but also conducts extensive research and development in this domain. This relentless patent activity is primarily aimed at safeguarding its battery technology.
Recently, a Japanese software company named Patent Result conducted a comprehensive study on EV patents and uncovered some intriguing findings. Between 2003 and 2022, BYD submitted over 13,000 patent applications, while Tesla, during the same period, only filed 863 patents. What’s even more striking is that more than half of BYD’s patent applications pertain to battery technology. This underscores BYD’s unique approach compared to other automakers since they internally develop their batteries. In contrast, most other manufacturers rely on third-party suppliers, making them more reliant on patents to protect their battery technology from imitation.
Batteries constitute a vital element of electric vehicles, and BYD’s approach differs significantly from its competitors. Developing in-house battery technology demands greater dedication and effort. However, other battery manufacturers might attempt to replicate their innovations by dissecting their battery packs. BYD’s blade battery, which uses lithium iron phosphate as the cathode material, has established itself as a leader in the development and production of this kind of battery. It offers superior safety and cost-effectiveness compared to nickel, cobalt, manganese (or aluminum) ternary lithium batteries. Nonetheless, filing patents comes with its own set of risks, as patent applications are made public, potentially enabling competitors to derive various technologies from them.
Take Tesla, for instance. Although Tesla has only submitted 863 patents over the past two decades, its research and development heavily rely on the utilization of publicly available information and software. Consequently, its patents largely relate to charging infrastructure and communication between electric vehicles and drivers. This highlights the divergent priorities in their EV development strategies. Tesla also employs advanced production techniques within its factories to reduce the risk of replication by other companies. The question that arises is whether BYD, with its extensive patent portfolio, can translate this into improved sales and challenge the dominant position of global EV leaders. The answer to this query may become apparent within the next 5 years, as the competition in the electric vehicle sector continues to intensify. (Image credit: BYD)
