摘要或動機

Reflex charging, or burp charge, is a prove method of effectively charging secondary\r
batteries under extremely high current. It is commonly used in military and aerospace\r
applications where short recharge time and long cell life are essential. Eric C. Darcy, a NASA\r
chemical engineer, in his 1998 PhD thesis, ‘Investigation of the response of Ni-MH cells to\r
burp charging’, outlined some of the most important theories behind this seemingly\r
miraculous technique. However, due to the technical limitations of his equipment, Darcy was\r
unable to determine the effects of varied reflex charging frequencies. This research overcame\r
this problem by using a purposed built multi-frequency programmable reflex charger\r
(PRESTO ALPHA I), and aimed to optimize chemical energy storage by searching for an\r
optimum charging frequency.
