How long does it take to discharge a battery at 1C rate?
At 1C, the discharge current will discharge the entire battery in one hour. The C Rate is the unit by which charge and discharge times are scaled.
What is the charge and discharge rate of a battery?
Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.
What is a 1C charge rate?
A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
What happens if a battery reaches 1C?
Losses at fast discharges reduce the discharge time and these losses also affect charge times. A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. Some high-performance batteries can be charged and discharged above 1C with moderate stress.
What is a charge discharge rate (C-rate)?
Charge-Discharge Rate (C-Rate): Performance and Response Time C-rate measures how quickly a battery charges or discharges. It is defined as: For instance, if a 10Ah battery is discharged at 10A, the discharge rate is 1C, meaning the battery will fully discharge in one hour.
How long can a battery be discharged?
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
