What are the 9 major parameters of Solar Lithium Batteries?

The capacity of a battery indicates the total amount of energy it can store. It is measured in ampere-hours (Ah). Higher capacity batteries can store more energy and provide longer run time. Solar lithium batteries usually come in a range of capacities, from small ones of 50 Ah to larger ones of 300 Ah or more. The capacity required depends on the power requirements of the solar system and the devices to be powered. For instance, a 100 W solar panel will require at least a 50 Ah battery for efficient performance.

The working voltage of a battery is the voltage range at which it can operate. For solar lithium batteries, the standard working voltage is 12V or 24V. These batteries offer a consistent voltage output and are ideal for use in solar systems and other standalone applications. The voltage output must match that of the device being powered. For example, a 12V battery is suitable for powering devices that require 12V input.

The discharge current of a battery is the current that flows out of it. It is measured in amperes (A). The discharge current determines the rate at which the battery can deliver power to the load. Higher discharge currents enable the battery to power high-load devices for a shorter period, while lower discharge currents allow for a longer runtime of low-load devices. Some solar lithium batteries can deliver discharge currents of up to 100A or more, depending on their capacity and size.

The charging current of a battery is the current that flows into it during charging. It is measured in amperes (A). The charging current determines the rate at which the battery can be charged. Higher charging currents enable faster charging of the battery, while lower charging currents allow for a gradual charging process, which may be beneficial for the battery's longevity. Solar lithium batteries have a wide range of charging currents, from a few amperes to 50A or more.

Cycle life refers to the number of charge and discharge cycles a battery can undergo before its capacity starts to degrade. Solar lithium batteries offer a longer cycle life compared to traditional lead-acid batteries. They can undergo up to 2000 cycles or more, depending on their quality and usage. For instance, a 100Ah lithium battery can undergo up to 2000 cycles and still maintain at least 80% of its original capacity.

The self-discharge rate of a battery refers to the rate at which it loses its charge while in storage. It is measured in percentage points per month. Solar lithium batteries have a low self-discharge rate, typically between 1% to 3% per month. This means that they can remain in storage for longer periods without losing their charge, making them suitable for emergency backup power.

The size and weight of a battery are essential factors to consider when choosing a solar lithium battery. Smaller batteries are ideal for portable devices or small solar systems, while larger batteries are suitable for larger solar systems and industrial applications. The weight of a battery determines how easy it is to handle. Solar lithium batteries come in a range of sizes and weights, from small ones of about 5Kg to larger ones of 40Kg or more.

The operating temperature range of a battery refers to the temperature range at which it can operate efficiently. Solar lithium batteries can operate efficiently within a temperature range of -20℃ to 60℃. They can withstand extreme weather conditions, making them ideal for use in off-grid solar systems and outdoor applications.

Solar lithium batteries have various protection functions that ensure their safety and longevity. These functions include overcharge protection, over-discharge protection, short-circuit protection, and overheat protection. These protection functions prevent the battery from being damaged due to factors such as overcharging, overheating, or over-discharging.
