【Disaster Prevention】How to Utilize the Battery of an Electrically Assisted Bicycle! Can be used for boiling water and heating as an emergency power source
There has been an increasing number of people using electric assist bicycles for commuting, going to school, and everyday shopping. What if we could utilize the battery of these familiar electric bicycles as disaster prevention goods...?
Bicycle batteries are useful for outdoor activities and disaster prevention!
The battery for electric assist bicycles has a large capacity of about 202Wh, providing a stable power source. However, generally, it cannot be utilized for purposes other than bicycles. Despite boasting an energy level comparable to mobile batteries, it was a challenging item to utilize for other applications.
This is where the "Chari Power PRO" inverter comes in, which transforms an electric assist bicycle's battery into a portable power supply. The battery you usually use can be employed directly for power outage measures. In addition to an enhanced maximum output of 520W, it comes with multi-cables and a spare fuse.
Designed to automatically recognize batteries from Panasonic, Yamaha, and Bridgestone available in Japan, it is reassuring during emergencies when there’s no room for complicated operations. Anyone can use it immediately just by setting the battery. There will be no more failures like the large capacity portable battery that naturally discharged over time without regular use...
The dedicated design supports batteries equipped with an electronic control system, constantly monitoring the charge and discharge temperature with a temperature sensor. When an anomaly is detected, the protection circuit activates.
With a multi-port design featuring pure sine wave AC output (1 outlet), USB-C (1 outlet), and USB-A (2 outlets), it can be used not only in emergencies but also for boiling water, running fans, or keeping warm with an electric blanket. Since it does not use fuel, it can be used in poorly ventilated areas or places where open flames are strictly prohibited, making it valuable for camping or car stays.
