For example, a 1C rate will fully charge or discharge a battery in 1 hour. At a discharge rate of 0.5C, a battery will be fully discharged in 2 hours. The use of high C-rates typically reduces available battery capacity and can cause damage to ...
WebDec 11, 2014 · A device’s time-current characteristics can be broken up into three different regions: Instantaneous – the initial period of an electrical fault, from zero up to several milliseconds. This portion of the device response is adjustable on more complex breakers. Short time – the period of time in the fault ranging from tenths of a second to ...
