It sounds like a reasonable idea if there is a surplus of production capacity of those type of modules in Japan.
Envision AESC's battery modules, produced in Zama, Japan, first will be supplied to Tocad Energy Co. which is responsible for producing the 8.2 kWh, 73 V packs, specially-developed for Yamaha.
"These 8.2kWh 73V specially-developed Yamaha golf cart battery packs contains battery modules and a battery management system (BMS) that governs charge and discharge. Envision AESC has supplied TOCAD ENERGY with lithium-ion battery modules it manufactures for electric vehicles and also similar modules, while TOCAD ENERGY has assembled the battery packs using its BMS, housings, and other components. Yamaha sells golf carts that using the battery packs from August 2019."
It's not clearly said that those are the same batteries as in case of Nissan LEAF, but we assume those are the same type and chemistry.
Taking into consideration that golf cars are a less demanding application than passenger cars, those type of modules might cope quite well.
Envision AESC Marketing and Sales Executive Vice President Nobuaki Yoshioka said:
“Lithium-ion batteries made by our company have been installed in over 470,000 electric vehicles and there has never been an instance of critical malfunction such as catching fire. The laminated cells are volumetric efficiency and have excellent heat dissipation properties, making them ideal for golf carts. We hope to use them in many other applications going forwards.”
TOCAD ENERGY CEO. & President Takeshi Fujikawa said:
“Our company has around 30 years’ experience developing and manufacturing rechargeable battery packs. Although so far, we have mainly developed and manufactured small battery packs for use in consumer and industrial machinery, we now intend to expand our business activities into high voltage and high capacity battery packs, starting with the development and manufacture of these large battery packs for Yamaha golf carts.”
