Nissan LEAF Batteries, Motors Will Power Electric Bus
Nissan LEAF batteries, motors and inverters will be used in full-size electric bus called “Yoka ECO Bus” developed by the Kumamoto University.
A single LEAF powertrain doesn’t have enough grunt to propel the bus, so the Japanese team decided to use three sets of batteries and motors.
The only proprietary part needed is a dedicated gearbox.
Tests of the Yoka ECO Bus are expected to begin in February and who knows, maybe if its successful Nissan will become a bus manufacturer in the future.
“Led by Kumamoto University, the initiative brings together talent and expertise from the automotive industry, government and academia. It is part of the university’s ongoing involvement with a Japanese Ministry of Environment project that aims to reduce or eliminate CO2 and other emissions from larger vehicles such as buses and trucks. Real-world testing is scheduled to begin in February in Kumamoto City in western Japan.
A major obstacle in creating large electric vehicles has been the high cost of development and parts, including batteries and electric motors. By using technology already conceived and perfected by Nissan, the cost of manufacturing electric buses can be greatly reduced.
The bus, named “Yoka ECO Bus,” will feature three batteries, three electric motors and an inverter from the Nissan LEAF, the world’s best-selling electric vehicle. Nissan is also developing a dedicated gearbox for the bus and offering technical support. The company hopes the technology can help the project achieve its goal of creating environmentally friendly buses for public transportation systems in Japan.”
Toshiro Matsuda, an associate professor at Kumamoto University and the project’s leader, said:
“We hope to improve Japan’s environment by standardizing the manufacturing of EV buses with help from the know-how of automakers. Our goal is to develop EV buses that are well-balanced in terms of being friendly to the environment and having low development costs.”
