What components does our stackable lithium batteries include?
Battery Cells: The lithium battery consists of multiple individual battery cells connected in series. Each cell typically has a nominal voltage of around 3.6-3.7 volts, depending on the specific lithium-ion chemistry used.
Battery Management System (BMS): The BMS is a critical component that monitors and manages the battery's operation. It ensures the proper charging, discharging, and balancing of the individual cells to maximize performance, longevity, and safety.
Enclosure: The battery cells and BMS are housed within an enclosure, which provides mechanical protection and electrical insulation.
Connectors and Terminals: The battery includes connectors or terminals that allow for external electrical connections. These connectors are used to link the battery to the equipment or system that will be powered by the battery.
Cooling System (Optional): In some cases, larger-scale 48V lithium batteries used in applications such as electric vehicles or data centers may incorporate a cooling system to manage the battery's temperature. This can include methods such as liquid cooling or air cooling to ensure optimal operating conditions and prevent overheating.
What is the main features that makes SunArk lithium battery suitable?
The 48V lithium battery has several key features that make it suitable for a range of applications:
Voltage Level: The 48V voltage level is often chosen for its balance between higher power capabilities and lower safety concerns compared to higher voltage systems.
Power Density: Lithium batteries have a higher power density compared to other battery chemistries, meaning they can deliver more power in a compact size.
Energy Density: Lithium batteries also exhibit high energy density, enabling them to store a significant amount of energy for their size and weight.
Longer Cycle Life: Lithium batteries generally have a longer cycle life compared to traditional lead-acid batteries.
Fast Charging: Lithium batteries can be charged at a faster rate compared to other battery types, allowing for quicker recharge times.
Lightweight and Compact: Lithium batteries are known for their lightweight and compact design, which makes them easier to integrate into various applications.
High Efficiency: Lithium batteries have high charge and discharge efficiencies, which means they can effectively convert and store energy with minimal losses.
Safety Features: Advanced 48V lithium batteries typically incorporate multiple safety features such as overcharge protection, over-discharge protection, short circuit protection, and thermal management systems. These safety measures help prevent potential hazards and ensure the safe operation of the battery.
What are main components of LiFEPO4 cells?
1. Positive Electrode (Cathode): The positive electrode is typically made of a lithium-based compound such as lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), lithium iron phosphate (LiFePO4), or lithium nickel cobalt aluminum oxide (NCA).
2. Negative Electrode (Anode): The negative electrode is commonly made of graphite or other carbon-based materials that can intercalate lithium ions.
3. Separator: The separator is a thin, porous material that keeps the positive and negative electrodes physically separated while facilitating the exchange of lithium ions.
4. Electrolyte: The electrolyte is a conductive solution or gel that contains lithium salts dissolved in an organic solvent. It serves as the medium for lithium ion transport between the electrodes.
5. Current Collectors: Current collectors are usually metal foils, such as aluminum for the cathode and copper for the anode.
What are the main process to produce a lithium battery pack?
1. Determine the battery bank requirements: Calculate the desired capacity and voltage for your battery bank based on your application needs.
2. Select suitable lithium batteries: Choose lithium batteries that meet your requirements and are designed for use in a rack configuration.
3. Choose a racking system: Select a racking system that is designed for the specific lithium batteries you are using.
4. Prepare the rack: Install the racking system and ensure it is securely mounted and stable.
5. Connect the batteries: Install the lithium batteries in the rack, following any guidelines provided by the battery manufacturer.
6. Configure the battery management system (BMS): If your lithium batteries require a BMS, install and configure it according to the manufacturer's instructions.
7. Test and verify: Once the batteries are properly racked and connected, perform thorough testing to ensure proper functioning and performance.
