TOKYO -- Chinese electric-vehicle maker BYD has taken an overwhelming lead in patent filings for EV technology, the arsenal of innovation fueling the company's emergence as a global player.

Nikkei, with the assistance of Tokyo-based analytics firm Intellectual Property Landscape, analyzed EV patent applications from China's four largest sellers of all-electric vehicles. BYD came out in front with 1,557 applications, nearly double the 870 filings of its closest rival, Zhejiang Geely Holding Group.

Chery Automobile was in third place with 640 patent filings, while SAIC Motor took fourth with 448.

When it comes to patent applications filed overseas, BYD far outpaces the other three contenders, indicating its strong ambitions for a global expansion.

BYD also possesses advanced technology on charging and discharging batteries. Of related patents held by the four Chinese players and Tesla, Intellectual Property Landscape ranked five from Tesla and five from BYD among the top 10 most important.

The top spot went to a patent BYD filed in 2013. That technology allows batteries to be charged under different power supply specifications without an expensive converter, and can be used to supply power between EVs or between an EV and an external power grid. It has been cited in at least 100 other related patents filed by Audi, Ford Motor, Hyundai Motor and other companies.

Batteries operate their best at specific temperatures. A patent BYD filed in 2017 involves technology that closely monitors batteries and adjusts their temperature.

Safety has been another priority for BYD. In 2017, it filed a patent for a vehicle design that protects batteries in an accident.

For decades the US has been making a big issue of intellectual property protections. At first, this was really promoted by Hollywood because the Chinese were pirating DVDs. However, it included all classes of IP as well, including patents.

Now China is producing more engineers and scientists than the US and is establishing a strong position in patents.
