With the gradual maturation of lithium battery technology, the lithium batteries on the market are mainly divided into 3 categories: consumer battery, power battery and energy storage battery according to the differences in battery application scenarios. So what are their definition? What are the differences in their application scenarios?
1. What is a consumer battery?
Consumer batteries are designed for consumer products. Consumer batteries are commonly used to power rechargeable consumer devices such as cell phones, camera, and laptops. These batteries tend to be easily accessible and on the more inexpensive side.
2. What is a power battery?
The power battery is used as the driving power battery for electric vehicles, electric bicycles, electric motorcycles, electric equipment, tools, drones, etc.
Power lithium batteries are also a kind of energy storage battery. It has higher performance requirements than conventional energy storage batteries because of the dimension and weight limitations and acceleration requirements at the startup of the electric vehicle, like higher energy density, faster charging, and discharging rate.
3. What is the energy storage battery?
Energy storage batteries mainly refer to batteries used for solar power generation equipment, wind power generation equipment and renewable energy storage energy.
With the popularization of solar power and wind power, many families and base stations are using the energy storage battery for electricity storage and use.
The Differences between Power Battery and Energy Storage Battery
1. Different application scenarios.
Power batteries are mainly used in new energy vehicles, electric robots, electric tools, etc., in pursuit of high energy density and power density; Energy storage batteries are used in power stations, communications base stations, etc., since most energy storage batteries do not need to be moved, energy storage lithium batteries do not have direct requirements for energy density.
2. The cycle life requirement is different.
The energy storage battery has higher requirements for cycle life than the power lithium battery; Taking electric vehicles as an example, the theoretical life of a ternary lithium battery pack is generally 1,200 times. According to the frequency of use, it is fully charged and discharged once every three days, and fully charged and discharged 120 times a year. The calendar life of a ternary lithium battery reaches ten years.
Energy storage batteries are charged and discharged more frequently. Under the premise of the same ten-year calendar life, there are higher requirements for cycle life. For example, energy storage power stations and household energy storage are charged and discharged once a day, the cycle life is generally required to be greater than 3500 times.
3. Different in cost structure.
In the energy storage battery system, the cost of the energy storage battery pack accounts for 60%, the cost of the battery inverter accounts for 20%, the energy management system (EMS) accounted for 10%, the battery management system (BMS) accounted for 5%, if it is a household, may require photovoltaic panels to build the off-grid system and so on. And power battery only battery cell costs accounted for up to 80%, the remaining 20% are battery management system, structural components, auxiliary materials, and so on.
