اطلاعات بیشترThe faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
The discharge rate provides you with the starting point for determining the capacity of a battery necessary to run various electrical devices. The product It is the charge Q, in coulombs, given off by the battery. Engineers typically prefer to use amp-hours to measure the discharge rate using time t in hours and current I in amps.
This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.
If a battery is being charged at 5 amps and has an energy rating of 20 Ah, the C rate is calculated as: \ [ C\ Rate = \frac {5} {20} = 0.25\ C \] This means the battery is being charged at a rate that is one-quarter of its total capacity per hour.
The discharge rate is usually expressed in terms of amperes (A) or milliamperes (mA). For example, a common AA battery has a discharge rate of about 2.4 A. That means that it can provide 2.4 A of current for one hour, or 1.2 A for two hours before it needs to be recharged.
When it comes to lithium-ion batteries, one of the most important performance metrics is the discharge rate. This measures how fast a battery can be discharged and is usually expressed in terms of amps or milliamps. The higher the discharge rate, the faster a battery can power a device.
