Sanoh Commences Supply of Ni-MH Batteries for Use in New Electric Motor-Assisted Bicycle

Sanoh Industrial Co., Ltd. has recently begun the supply of Ni-MH battery packs and chargers to be used as the power source for the foldable electric motor-assisted bicycle, the Intelligent Bike, as well as the electric motor assist attachment unit for bicycles, the Intelligent Bike Kit, manufactured by Sunstar Engineering Inc.

The Intelligent Bike was designed for the convenience of collapsibility to be compact as well as lightweight, and at the same time, to ensure an increased motor-assisted capability. Therefore, the battery to power such a design needed to be small, possess a high capacity, and demonstrate high performance output.

Sanoh refined the existing Ni-MH battery technology and improved its volume efficiency by minimizing the conventional C size battery by 10mm in height. Achieving both a higher capacity (20% improvement in energy density compared to Sanoh’s conventional batteries) and higher performance (30% improvement in output power density compared to Sanoh’s conventional batteries), Sanoh succeeded in the development of a Small-C size battery. The improved Ni-MH battery was able to meet the required performance levels, and the positive performance evaluation results led to the adoption of Sanoh’s Ni-MH batteries by Sunstar Engineering.

* Sunstar Engineering Inc. boasts the largest market share in the world for the supply of sprockets and brake disks for motorcycles.

Sanoh Ni-MH Battery Specifications:
– Size: Small-C
– Capacity: 3.4 Ah
– Voltage: 24.0 V (using 20 cells)
– Charger: Exclusive charger
