Many people are unfamiliar with the concept of battery rate, and many have also had the experience of being unfamiliar with it but not knowing where to start. Today, I'll guide you through learning about the concepts of battery rate and discharge rate, and also take a look at high-rate batteries, because generally when we talk about rate and discharge rate, we're referring to high-rate batteries, which is unavoidable.
Battery capacity
The charge/discharge rate is used to express the charge/discharge capacity of a battery, and the unit is C. 1C represents the current intensity when the battery is fully discharged in one hour. For example, an 18650 battery with a nominal capacity of 2200mA·h will be fully discharged in one hour at a 1C intensity, and the discharge current will be 2200mA.
Battery discharge rate
Discharge rate is related to the discharge rate. For example, 1C indicates the current intensity when the battery is fully discharged in one hour. What about a discharge rate of 0.5C? Or a discharge rate of 10C, 20C, etc.? This is called discharge rate. In fact, it's the other way around: the discharge rate is a certain multiple, and then multiplied by the original 1C to get the discharge rate.
High-rate batteries
High-rate batteries, as opposed to standard-rate batteries, represent the charging and discharging capabilities of lithium-ion polymer batteries. High-rate batteries are divided into discharge rate and charge rate, denoted by "C" to indicate the ratio of the battery's charging and discharging current. For example, for a 1200mAh battery, 0.2C represents 240mA (0.2 times the 1200mAh capacity), and 1C represents 1200mA (1 times the 1200mAh capacity).
With the development of various industries, higher discharge and faster charging requirements are being placed on batteries, which in turn has promoted the technological improvement and application of high-rate batteries. Currently, high-rate batteries are widely used in products that require high-rate discharge, such as aerial photography drones, agricultural plant protection drones, emergency jump starters, model airplanes, and power tools.
