Power Batteries

Power batteries are designed for high-current applications. They are commonly used in electric vehicles, industrial machines, and emergency power supplies that require high energy in short periods. They have high C-values, meaning they can provide large amounts of energy in very short periods. For example, a power battery can have a C-value of 10C or higher, which means it can provide current equal to 10 times its capacity.

Starting Batteries

Starting batteries are used to start vehicle engines. These batteries provide high current for short periods to enable quick engine start. They are widely used in automobiles, trucks, and other motor vehicles. Starting batteries can have high C-values like power batteries as they are designed to provide high current for short durations.

Energy Storage Batteries

Energy storage batteries are designed for systems requiring continuous and long-term energy supply. These batteries typically have low C-values, meaning they have capacity for longer-term energy provision. Energy storage batteries are used in solar and wind energy systems, backup power sources, and applications requiring low current.

C Value and Applications: Theoretical and Practical Information

What is C Value and How is it Calculated?

C value is a measure that determines how quickly a battery can be charged or discharged relative to its capacity. The C value expresses the charge or discharge current based on the battery’s capacity. For example, a 1C value indicates that the battery can be completely charged or discharged in one hour.

Example C Capacity Calculation

• Battery Capacity: 54 Ah
• Maximum Continuous Discharge Current: 60A
• Maximum Instantaneous Discharge Current: 100A
