Abstract
As the e-Bike market continues to grow without effective standardization, fatal battery fires (especially among cheaper alternative products) have become increasingly common. Dartmouth College (and many universities nationally) prohibit unsupervised indoor charging of e-Bikes without offering suitable alternative charging solutions. Enter the Fire-Safe e-Bike Charging Locker, which provides a safe charging location for e-Bike batteries. Targeting academic institutions and shared housing communities as buyers, the locker provides peace of mind and reduced insurance rates due to decreased safety risks. The locker prevents these fires through use of a thermal infrared camera, which detects abnormal increases in battery temperature before they reach dangerous levels, and initiates a battery shutoff. Currently, market solutions exist only to detect and extinguish fires, resulting in destruction of the battery. Our product allows for potential continued use of the battery, and a complete prevention of lithium-ion battery fires which can spread dangerously out of control.
