How to choose a BMS for lithium batteries?
To build safe-high performance battery packs, you need to know how to choose a BMS for lithium batteries. The primary job of a BMS is to prevent overloading the battery cells. To be effective, the maximum rating on the BMS should be greater than the maximum amperage rating of the battery.
What are the components of a lithium-ion battery pack?
In the lithium-ion battery pack, there are the main electronic modules: the batteries (cells) connected in groups in parallel and series, the cell contact system, and the BMS (battery management system). The BMS is the brain of the battery pack.
What does a BMS prevent in lithium-ion batteries?
A BMS prevents your battery cells from being drained or charged too much. Another important role of the BMS is to provide overcurrent protection to prevent fires. Lithium-ion batteries do not require a BMS to operate, but a lithium-ion battery pack should never be used without a BMS.
How does a battery management system (BMS) work?
A battery management system (BMS) monitors the cell voltage of each cell group. If any of them go lower than a certain threshold (usually around 2.6 volts), the BMS disconnects the cells to prevent damage. During charging, a high voltage is applied across many sets of lithium-ion cells in series.
What is a BMS in a battery pack?
A BMS is a PCBA (printed circuit board assembly) in the battery pack. The main components mounted on the BMS printed circuit board include: Microcontroller (MCU): It gathers and processes current signals from the CCS to monitor the voltages and temperatures of the cells.
Why do lithium batteries need a battery management system?
But the conditions of use are stricter. Therefore, nearly all lithium batteries on the market need to design a lithium battery management system. to ensure proper charging and discharging for long-term, reliable operation. A well-designed BMS, designed to be integrated into the battery pack design, enables monitoring of the entire battery pack.

High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
