What is BMS overcharge protection?
BMS overcharge protection is a common battery management system (BMS) protection setting for lithium batteries. If the voltage of a lithium battery exceeds the maximum safe level, overcharge protection will activate and stop current from flowing into or out of the battery. This prevents further damage to the battery and helps ensure safety.
Why do lithium batteries need a BMS?
Overcharging or discharging a lithium-ion battery can shorten its life and even cause safety hazards. A BMS prevents this by automatically disconnecting the battery from the charger or load when it reaches unsafe levels, safeguarding the battery and preventing potential damage.
How does the battery management system (BMS) work?
If you’re using a lithium battery in your project, it’s important to understand the basics of how the Battery Management System (BMS) works. The BMS protection board for li-ion is responsible for monitoring and protecting the battery cells, and it has many settings that you need to be aware of.
What does BMS mean in a battery?
At its core, BMS stands for Battery Management System. It's an essential component for lithium-ion batteries, which are commonly used in electric vehicles (EVs), energy storage systems (ESS), and other devices that require rechargeable batteries.
How does a BMS protect a battery?
According to the purpose of protection, the battery is only allowed to discharge and the charging relay is disconnected. Generally, the BMS will set some warning voltages within the allowable voltage. When the battery reaches this voltage, the BMS will issue a request to reduce the charging current.
Does a battery balancing system need a BMS?
However, most lithium batteries do not have such built-in cell balancing capabilities and will require the BMS to perform this function. If the BMS is not able to properly balance the cells in a battery pack, it can cause cell damage and even failure.
Featured Solar Products

They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
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.
