Currently, the Japanese pure electric vehicle battery research mainly concentrated in the lithium battery, followed by sodium lead-acid battery, nickel metal hydride batteries and battery, etc.
From the perspective of the total amount of the world within the scope of the patent application, Japan has a pure electric vehicle battery and its management system is the most relevant patent applications.
From the point of view of domestic patent applications, in and pure electric vehicle battery and its management system about 6782 patent applications, more than 90% of the patent application from the applicant.
Both from the perspective of the ownership of an application for a patent for the world, and Japanese applicants from Japan patent application Angle, the share of the Japanese in the field of pure electric vehicle battery and its management system are the most strong power, control the most patent technology.
At present, the German pure electric vehicle battery research mainly concentrated in the lithium battery, followed by sodium lead-acid battery, nickel metal hydride batteries, batteries and air batteries etc.
From the perspective of the total amount of the world within the scope of the patent application, as of June 2010, Germany's pure electric vehicle battery and its management system related patent application number ranked sixth in the world, and the top of the difference in the number of patents in Japan, accounts for only 11% of Japan's filings.
From the point of view of domestic patent applications, Germany the applicant holds a patent accounted for about 43% of the total, Japan is higher than the second.
On a global scale, Germany in the pure electric vehicle battery and its management system in the field of technical strength is far less than Japan, but in its scope, Germany has the strong technical advantage, battery patent ownership is higher than Japan.
