What does 1C mean on a car battery?
1C means 1 hour discharge time. 2C means 1/2 hour discharge time. 0.5C means 2 hour discharge time. In many applications, the battery rate is very important. For example, we want the car to be fully charged within half an hour, instead of waiting for 2 hours, or even 8 hours. What is cause influence to the battery C rating?
What is the charge and discharge current of a battery?
The charge and discharge current of a battery is measured in C-rate. Most of portable batteries are rated at 1C. This means that a 1000mAh battery would provide 1000mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C would provide 500mA for two hours.
What does a 1C charge rate mean?
If the result is 1C, the battery discharges at a rate equal to its full capacity in one hour. A 2C rate indicates the battery discharges at double its capacity per hour, meaning it would discharge fully in 30 minutes. Charging C-Rate
What is the discharge rate of a lithium ion battery?
Smaller batteries are rated at a 1C discharge rate. Due to sluggish behavior, lead acid is rated at 0.2C (5h) and 0.05C (20h). While lead- and nickel-based batteries can be discharged at a high rate, the protection circuit prevents the Li-ion Energy Cell from discharging above 1C.
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.
How many amps does a 1C battery provide?
If the same battery is discharged at a 1C rate, it will provide 100 amps for one hour, and at a 0.5C rate, it will provide 50 amps for two hours. Knowing the C rating is crucial because the available stored energy in a battery depends on the speed of the charge and discharge currents.
