Racing group Team TAISAN and materials engineer Power Japan Plus have formed a partnership to develop an electric racing vehicle, which will be the first in the world to use the Ryden dual carbon battery.
Under this partnership, Power Japan Plus will provide Ryden cells and Team TAISAN will leverage its vast experience in international racing to optimize the battery and develop a battery pack and management circuit. A go-kart powered by the Ryden dual carbon battery will begin test driving August of this year.
“We have faced a number of issues with electric vehicle batteries up until now. The Ryden battery from Power Japan Plus is the solution we have been searching for,” said Yasutsune Chiba, owner of Team TAISAN. “We will first develop a battery capable of withstanding the rigorous demands of racing, before advancing the technology for use in commercial applications.”
Team TAISAN has faced many roadblocks with conventional battery technology, the danger of thermal runaway being the most prevalent. Intense heating prevented other electric vehicle (EV) racing cars used by TAISAN from running continuously. In searching for a solution to this problem, Team TAISAN discovered the Ryden dual carbon battery developed by Power Japan Plus.
The Ryden dual carbon battery wields an energy density comparable to lithium-ion batteries, with a much faster charge time. In addition, Ryden is resistant to heating during operation, mitigating the threat of thermal runway and yielding a simpler battery pack cooling system.
Development will start with a go-kart powered by the Ryden dual carbon battery, which will undergo endurance testing in harsh summer heat conditions this August. The team will then build a full scale EV racing car driven by a Ryden battery pack. Team TAISAN will conduct endurance and safety tests on the electric racing vehicle at its facilities in Chiba Prefecture, Japan, with a goal for the vehicle to debut in a Japanese EV racing competition.
Established in 1983, Team TAISAN is recognized as one of Japan’s most prestigious racing teams, with a total count of 72 victories. Among these victories, Team TAISAN has won 13 Japanese national racing championships – eight during the last 20 years – at the All Japan Grand Touring Car Championship (JGTC) / Super GT (SGT). The team has also won six overseas championships, including The 24 Hours of Le Mans in the GT class in its very first attempt, going on to complete the race a total of six times.
The team has also been actively involved in EV endurance racing in Japan. Team TAISAN was an early adopter of the Tesla Roadster, champion at the 2011 ALL JAPAN EV-GP SERIES, as well as the modified EV Porsche 916 model, which completed four, one-hour endurance races hosted by the EV Club, with third place honors in the lead-based battery class.
The partnership was announced publically prior to the start of the 24 Hours of Le Mans race this past Saturday in Le Mans, France.
