What is the difference between a power battery and an energy storage battery? How to distinguish between a power battery and an energy storage battery If batteries are classified according to application scenarios, they can be divided into three categories: consumer-grade batteries, power batteries, and energy storage batteries. So what is the difference between power batteries and energy storage batteries? The specific content is as follows: 1. Different application scenarios Power batteries are mainly used in vehicles such as new energy vehicles, electric bicycles, and electric trains, while energy storage batteries are mostly used as batteries for renewable energy such as solar power, wind power, and hydropower.   2. The life cycle is different Among the current mainstream power batteries, the life of ternary lithium batteries is generally 1200 charge and discharge cycles, and that of lithium iron phosphate batteries is 2000 times. Energy storage batteries have higher requirements for cycle life due to more frequent charge and discharge. , the life of the general energy storage battery is required to be 3500-5000 charge and discharge cycles.   3. Different volume Power batteries are mostly used in new energy vehicles. The volume of a battery is equivalent to a dozen or twenty large carpets stacked together, while energy storage batteries are generally composed of multiple battery modules to form a large module, and then composed of many large modules. The volume is close to the energy storage battery of a container.   4. Different cost structures In the energy storage battery system, the cost of the battery accounts for 60%, the cost of the energy storage inverter accounts for 20%, the energy management system accounts for 10%, and the High Voltage BMS(battery management system) accounts for 5%. In the power battery, the cost of battery cells alone accounts for as high as 80%, and the remaining 20% ​​are BMS(battery management systems), structural parts, auxiliary materials, etc.   As for how to distinguish between power batteries and energy storage batteries, the easiest way is to look at the purpose of the batteries. At present, power batteries are mostly used as the power source of new energy vehicles, while energy storage batteries can basically only be used in solar power stations and wind power stations. , hydroelectric power stations and other places can be found.   High Voltage BMS/Solar BESS BMS/Lithium BMS/Battery BMS/Lifepo4 BMS/Overall Solution BMS/OEM UPS BMS/ESS Integrated BMS/768V UPS BMS/Home BESS BMS/Lifepo4&NMC    

What is the function of BMS? A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.   A battery pack built together with a battery management system with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a smart battery charger.   Protection A BMS may protect its battery by preventing it from operating outside its safe operating area, such as: Over-charging Over-discharging Over-current during charging Over-current during discharge Over-voltage during charging, especially important for lead–acid, Li-ion and LiFePO4 cells Under-voltage during discharging, especially important for Li-ion and LiFePO4 cells Over-temperature Charging while under low temperature Over-pressure (NiMH batteries) Ground fault or leakage current detection (system monitoring that the high voltage battery is electrically disconnected from any conductive object touchable to use like vehicle body) The BMS may prevent operation outside the battery's safe operating area by: Including an internal switch (such as a relay or mosfet) which is opened if the battery is operated outside its safe operating area Requesting the devices to which the battery is connected to reduce or even stop using or charging the battery. Actively controlling the environment, such as through heaters, fans, air conditioning or liquid cooling   Balancing In order to maximize the battery's capacity, and to prevent localized under-charging or over-charging, the BMS may actively ensure that all the cells that compose the battery are kept at the same voltage or State of Charge, through balancing. The BMS can balance the cells by: Wasting energy from the most charged cells by connecting them to a load (such as through passive regulators) Shuffling energy from the most charged cells to the least charged cells (balancers) Reducing the charging current to a sufficiently low level that will not damage fully charged cells, while less charged cells may continue to charge (does not apply to Lithium chemistry cells)   Battery connection to load circuit A BMS may also feature a precharge system allowing a safe way to connect the battery to different loads and eliminating the excessive inrush currents to load capacitors. The connection to loads is normally controlled through electromagnetic relays called contactors. The precharge circuit can be either power resistors connected in series with the loads until the capacitors are charged. Alternatively, a switched mode power supply connected in parallel to loads can be used to charge the voltage of the load circuit up to a level close enough to battery voltage in order to allow closing the contactors between battery and load circuit. A BMS may have a circuit that can check whether a relay is already closed before precharging (due to welding for example) to prevent inrush currents to occur.   Communication The central controller of a BMS communicates internally with its hardware operating at a cell level, or externally with high level hardware such as laptops or an HMI. High level external communication are simple and use several methods Different types of serial communications. CAN bus communications, commonly used in automotive environments. Different types of wireless communications. Low voltage centralized BMSes mostly do not have any internal communications. Distributed or modular BMSes must use some low level internal cell-controller (Modular architecture) or controller-controller (Distributed architecture) communication. These types of communications are difficult, especially for high voltage systems. The problem is voltage shift between cells. The first cell ground signal may be hundreds of volts higher than the other cell ground signal. Apart from software protocols, there are two known ways of hardware communication for voltage shifting systems, optical-isolator and wireless communication. Another restriction for internal communications is the maximum number of cells. For modular architecture most hardware is limited to maximum 255 nodes. For high voltage systems the seeking time of all cells is another restriction, limiting minimum bus speeds and losing some hardware options. Cost of modular systems is important, because it may be comparable to the cell price.Combination of hardware and software restrictions results in a few options for internal communication: Isolated serial communications wireless serial communications To bypass power limitations of existing USB cables due to heat from electrical current, communication protocols implemented in mobile phone chargers for negotiating an elevated voltage have been developed, the most widely used of which are Qualcomm Quick Charge and MediaTek Pump Express. "VOOC" by Oppo (also branded as "Dash Charge" with "OnePlus") increases the current instead of voltage with the aim to reduce heat produced in the device from internally converting an elevated voltage down to the battery's terminal charging voltage, which however makes it incompatible with existing USB cables and relies on special high-current USB cables with accordingly thicker copper wires. More recently, the USB Power Delivery standard aims for an universal negotiation protocol across devices of up to 240 watts.   Computation Additionally, a BMS may calculate values based on the below items, such as:[citation needed] Voltage: minimum and maximum cell voltage State of charge (SoC) or depth of discharge (DoD), to indicate the charge level of the battery State of health (SoH), a variously-defined measurement of the remaining capacity of the battery as % of the original capacity State of power (SoP), the amount of power available for a defined time interval given the current power usage, temperature and other conditions State of Safety (SOS) Maximum charge current as a charge current limit (CCL) Maximum discharge current as a discharge current limit (DCL) Energy [kWh] delivered since last charge or charge cycle Internal impedance of a cell (to determine open circuit voltage) Charge [Ah] delivered or stored (sometimes this feature is called Coulomb counter) Total energy delivered since first use Total operating time since first use Total number of cycles Temperature Monitoring Coolant flow for air or liquid cooled batteries   Monitor A BMS may monitor the state of the battery as represented by various items, such as: Voltage: total voltage, voltages of individual cells, or voltage of periodic taps Temperature: average temperature, coolant intake temperature, coolant output temperature, or temperatures of individual cells Coolant flow: for liquid cooled batteries Current: current in or out of the battery Health of individual cells State of balance of cells

Is the lithium battery mosfet and BMS battery management system the same thing?     1.What is lithium battery mosfet?         During the use of lithium batteries, under certain conditions, overcharging and overdischarging may change the internal battery, thus affecting the performance and life of the battery. Severe cases may even explode. The function of the lithium battery mosfet is to protect the battery. In most cases, the power lithium battery must be used together with the mosfet to ensure the safety and reliability of the whole system.   The main function of lithium battery mosfet   1. Overcharge protection function: It means to stop charging when a certain voltage is reached. 2. Over-discharge protection function: Over-discharge protection function is to stop discharging to the load when the battery voltage becomes low. 3. Over-current protection function: stop discharging the load when consuming high current. The purpose of this function is to protect the battery and MOS tube to ensure the safety of the battery in the working condition. 4. Short-circuit protection function: It is the core of the protection chip.   2.What is BMS battery management system?         BMS battery system, commonly known as battery nanny or battery housekeeper, is mainly used to intelligently manage and maintain each battery cell, prevent battery overcharge and overdischarge, extend battery life and monitor battery status.     Functions of BMS battery management system   1、Measurement of battery terminal voltage 2、Energy balance between single cells 3、Measurement of the total voltage of the battery pack 4、Measurement of total battery pack current 5、SOC calculation: estimating the remaining power of the power battery 6、Dynamic monitoring of the working status of the power battery pack: prevent the battery from overcharging or overdischarging. 7、Real-time data display 8、Data recording and analysis: maintain the reliability and efficiency of the whole battery operation 9、Communication network function.   3.The difference between Li-ion battery mosfet and BMS battery management system   BMS battery management system and Li-ion battery protection Mosfet are both the umbrella of Li-ion battery, but BMS management system is equivalent to the brain of Li-ion battery, more intelligent, editable and equipped with battery management software. The Mosfet is the original IC MOS plus some resistors and capacitors, which is hardware protection. Compared with the Mosfet, BMS battery management system is easier to operate and more convenient.BMS battery management system is important to ensure the safety of electric vehicles, charging station equipment and personnel.

  BMS — which stands for Battery Management System — is a vital part of any Lithium-ion Battery.   While lithium-ion batteries — especially LiFePO4 batteries — are a popular choice for energy storage systems, they can be dangerous if not handled properly. That’s why it’s crucial to use the correct BMS in your battery pack.   A LiFePO4 BMS controls the discharge and charge processes of LiFePO4 battery packs. So if anything goes wrong during these processes, the BMS protection immediately kicks in and adjusts the charging parameters or cuts off the power flowing to and from the battery pack entirely. Moreover, a BMS monitors the battery cells and makes sure they’re all working together correctly. It also measures parameters like voltage, current, and temperature to ensure that the battery is healthy and safe.   Additionally, a BMS optimizes your battery capacity and overall performance in every charge/discharge process. This way, you can get the most out of your LiFePO4 battery pack regarding performance and lifespan.   GCE is a well-known BMS company in China, with 10 years of experience in R&D and production of LifePO4 BMS.  

One important advantage over other lithium-ion chemistries is thermal and chemical stability, which improves battery safety.   https://www.maoyt.com/index.php?r=product/edit&pid=26472180 https://www.alibaba.com/product-detail/384V-63A-Lifepo4-BMS-lithium-battery_1600390378034.html?spm=a2747.product_upgrade.0.0.b52a71d2acMu1d   LiFePO4 is an intrinsically safer cathode material than LiCoO2 and manganese dioxide spinels through omission of the cobalt, with its negative temperature coefficient of resistance that can encourage thermal runaway. The P–O bond in the (PO4) ion is stronger than the Co–O bond in the (CoO2)− ion, so that when abused (short-circuited, overheated, etc.), the oxygen atoms are released more slowly. This stabilization of the redox energies also promotes faster ion migration.   As lithium migrates out of the cathode in a LiCoO2 cell, the CoO2 undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO4 are structurally similar which means that LiFePO4 cells are more structurally stable than LiCoO2 cells.   No lithium remains in the cathode of a fully charged LFP cell. (In a LiCoO2 cell, approximately 50% remains.) LiFePO4 is highly resilient during oxygen loss, typically resulting in an exothermic reaction in other lithium cells. As a result, LiFePO4 cells are harder to ignite in the event of mishandling (especially during charge). The LiFePO4 battery does not decompose at high temperatures.   Based on the principle of safety first, we do not recommend customers to use NMC batteries and do not bear the risk of batteries. The voltage parameters of our high-voltage BMS are designed according to the nominal voltage of Lifepo4 3.2V. Of course, after explaining the potential risks, we can also adjust the parameters of our BMS according to customer requirements to adapt to NMC (3.6V) LTO (2.3V) )system.
