Nissan has developed a new generation ultra-small electric vehicle (Hypermini) since 1997 for introduction into the domestic market beginning October of 1999. This is the first brand-new EV to retail in Japan available for two passengers. The Hypermini includes the same technologies as the Altra-EV which was released in the California market in January of 1998, as 1. Lithium - ion Battery system 2. Permanent magnet synchronous motor 3. Inductive charging system The new type lithium-ion battery uses Manganese instead of Cobalt to reduce material costs. The neodymium-iron boron magnet type motor is installed in the rear. This motor features a compact design by means of integrating the inverter and the control unit. It generates a maximum power of 24 kW and a maximum torque of 133 Nm. The new generation inductive charger system(GEN3) that will have been standardized in the United States and Japan is installed in the front hood. The platform and the body that have been developed are an all-new design. The body is made of Aluminum and features a space frame structure. The battery pack is mounted underneath the floorboard between the wheels. The Hypermini also has a remote controller that has two way data communication. This remote. controller includes a keyless entry system and provides a visual readout of the remaining capacity of the batteries from outside the vehicle. This report shows the specifications, performance, and characteristics of the various components. The Hypermini could propose a new automobile transportation system for the 21st century, with equivalent vehicle fuel consumption of 50 km/l and CO2 emission of about 40 g/km.
