What are the differences between power lithium batteries and energy storage lithium batteries?

Let's analyze the difference between power lithium battery and energy storage lithium battery?

1. Different battery capacity

For new batteries, use a discharger to test the battery capacity. Generally, the capacity of power lithium batteries is about 1000-1500mAh.

The capacity of energy storage lithium battery pack is above 2000mAh, and some can reach 3400mAh.

2. Application industry

Power lithium batteries are used to drive the power supply of electric vehicles, electric bicycles, electric motorcycles, electrical equipment and tools, and are used in power transmission and substations to provide closed current for power devices.

Energy storage lithium battery packs are mainly used in water, heat, wind, solar and other energy storage power stations, auxiliary services for peak regulation and frequency regulation, digital products, power products, medical security, UPS power supplies, etc.

3. Small lithium battery battery management system BMS has different locations.

In the energy storage system, the energy storage lithium battery interacts with the energy storage converter only at high voltage. The converter takes power from the AC grid to charge the battery pack or the battery pack supplies power to the converter and passes through the power converter. The converter converts to alternating current and feeds it into the alternating current grid.

The BMS of an electric vehicle has an energy exchange relationship with the motor and the charger under high voltage.

4. Different in nature

Power lithium batteries refer to batteries that power transportation, and are often associated with small batteries that power portable electronic devices.

The general energy storage lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte, which is different from lithium ion secondary batteries and lithium ion polymer batteries.
