Industrial and commercial energy storage is a major type of user-side energy storage system, which reduces the electricity bills of industrial and commercial owners by maximizing the self-consumption rate of photovoltaics. It mainly implements functions such as energy time shifting, peak-valley price difference arbitrage, capacity electricity fee reduction and demand response. This article will provide a detailed analysis of industrial and commercial energy storage, including its classification, main components and their functions, as well as key conditions that need to be understood.

Industrial and commercial energy storage systems are mainly divided into two categories: standard boxes and non-standard boxes. TEUs are generally designed based on 20-foot or 40-foot containers and have an energy storage capacity of 215KWh. Non-standard containers are customized according to specific working conditions, and the capacity is determined according to actual needs.

The main components of industrial and commercial energy storage systems include outer boxes, batteries, battery management systems (BMS), PCS (converters), EMS (energy management systems), junction cabinets, fire protection systems, cooling systems, electrical control systems, and various connections. devices and auxiliary equipment, etc.

The outer box plays a role in aesthetics and protecting internal components, ensuring the safety and reliability of the system. The battery is the part that stores electrical energy and consists of cells, battery packs and battery clusters. BMS is a battery management system that can protect the voltage, current and temperature of the battery system, while performing balanced charging to ensure that each battery is in optimal condition.

PCS is a converter that converts the DC power stored in the energy storage device into AC power, allowing the energy storage system to interact with the mains or load. EMS is an energy management system, responsible for functions such as data collection, network monitoring, energy scheduling, and network data analysis. The combining cabinet is used to collect the current of each battery cluster and perform centralized regulation.

Industrial and commercial energy storage systems also need to be equipped with fire protection systems, using heptafluoropropane fire extinguishing agent, which has the functions of temperature insulation, flame retardant and explosion-proof to ensure the safety of the system. The cooling system uses air cooling or liquid cooling to cool the battery pack and internal heating components to ensure the normal operating temperature of the system.

In addition, the energy storage system also requires an electronic control system for operation control, including buttons, APP online monitoring and communication functions. Various connectors are responsible for connecting wire harnesses, plug-ins, copper bars and other parts. Auxiliary equipment such as transformers, DCDC converters and auxiliary lighting play a supporting role.

There are also some key considerations to consider when understanding commercial and industrial energy storage systems. The first is the application usage scenario. It needs to be clear whether it is used in a microgrid or needs to be connected to the grid. The second is the power generation method. It is necessary to understand the photovoltaic input power, the total power of the PCS, the total battery power and the required voltage, as well as the voltage conditions required for grid connection. Finally, the heat dissipation method is also a factor that needs to be considered. Currently, the common heat dissipation methods are air cooling and liquid cooling.

As an effective energy management method, industrial and commercial energy storage systems can maximize the use of photovoltaic power generation and reduce electricity bills. By understanding the classification, main components and key conditions of industrial and commercial energy storage, we can better understand and apply this technology to provide more efficient and economical power solutions for industrial and commercial owners

All in all, commercial and industrial energy storage plays an important role in energy management and electricity bill reduction. By rationally selecting the classification of energy storage systems and understanding the functions and key conditions of each main component, industrial and commercial owners can maximize the self-use rate of photovoltaic, reduce electricity expenses, and achieve energy time shift, peak-valley price difference arbitrage, capacity electricity fee reduction and Demand response and other functions.

With today’s growing focus on environmental protection and sustainability, the rise of electric vehicles presents a major challenge before us. As the core technology of electric vehicles, power battery technology is responsible for driving and storing electric energy, and is leading the transformation of the automotive industry. This article will analyze the power battery technology in depth, and elaborate on its components, functions of each part and common application fields.

The components of power battery technology mainly include battery cells, battery management system (BMS), cooling system and electrical control unit (ECU). The first is the battery cell, which is the basic unit of power battery technology. It consists of multiple battery cells to form a battery pack, which is responsible for storing and releasing electric energy. Common battery cells include chemistries such as lithium-ion, nickel metal hydride, or lithium cobalt oxide.

The second is the battery management system (BMS), whose function is to monitor and control the state of the battery pack. BMS protects the battery from adverse conditions such as overcharge, overdischarge, and overheating by monitoring the parameters of the battery such as temperature, voltage, current, and status. In addition, the BMS can perform balanced charging to ensure that each battery cell is working at its best, improving the overall performance and life of the battery pack.

In order to control the temperature of the battery pack, power battery technology needs to be equipped with a cooling system. The cooling system can effectively control the temperature of the battery by circulating coolant or air to avoid battery performance degradation or damage caused by overheating. A good cooling system can improve the stability and reliability of the battery pack.

The electrical control unit (ECU) is the computer responsible for controlling and managing the entire electric vehicle powertrain. The ECU communicates with the battery pack, electric motor, and other sensors to enable efficient conversion and management of electrical energy. By controlling the output power of the battery, the ECU can ensure that electric energy can be supplied to the electric motor as needed to realize the power output of the vehicle.

Power battery technology is also expanding beyond traditional application fields, and has achieved remarkable success. The most common application field is electric vehicles (EV). Power battery technology is the core technology of electric vehicles. It drives electric vehicles by storing and releasing electric energy to achieve green travel. In addition, power battery technology is also used in hybrid electric vehicles (HEV). HEV uses power batteries to store and release energy, and drives the car together with the internal combustion engine, reducing fuel consumption and emissions while improving efficiency.

In addition to its wide application in the automotive field, power battery technology can also be applied to energy storage systems, such as home and industrial energy storage systems. These energy storage systems can balance energy supply and demand, realize efficient energy utilization and peak-valley shaving, and promote the development of clean energy.

Power battery technology is the core technology of electric vehicles, and its components analyze the functions and functions of battery cells, battery management systems (BMS), cooling systems and electrical control units (ECUs) in detail. In addition, the article explores common application areas for traction battery technology, including electric vehicles (EV), hybrid electric vehicles (HEV), and energy storage systems. Through a deep understanding of the composition and function of power battery technology, we can better understand and realize the importance and advantages of this technology.

These advanced technologies have pushed electric vehicles to a new stage of development, making important contributions to sustainable transportation and clean energy. In the future, with the continuous innovation and progress of technology, power battery technology will continue to evolve, promote the development of electric vehicles, and create a more environmentally friendly and sustainable way of travel for us.

The cycle life of a Lithium iron phosphate (LiFePO4) battery is more than 4 to 5 times that of other lithium ion polymer batteries. The operating temperature range is wider and safer; however, the discharge platform is lower, the nominal voltage is only 3.2V, and the fully-charged voltage is 3.65V. Lithium iron phosphate is mostly used to replace traditional lead-acid batteries. We also often find that lithium iron phosphate batteries are used in household solar energy systems, fishing, golf carts, outdoor portable energy storages, and electric motorcycles.

What is a Lithium iron phosphate battery?

Lithium-ion polymer (LIPO) battery

A lithium ion polymer battery is a kind of rechargeable battery that mainly relies on the movement of lithium ions between positive electrode and negative electrode to work. Lithium ion batteries use an intercalated lithium compound as an electrode material. At present, the commonly used cathode materials for lithium ion batteries are: lithium cobalt oxide (LCO battery), lithium manganate (LMO battery), lithium-ion ternary (NCA, NMC battery), and lithium iron phosphate (LiFePO4 battery).

Lithium iron phosphate (LiFePO4, LFP) battery

A lithium iron phosphate battery is a type of lithium ion polymer battery that uses LiFePO4 as the cathode material and a graphitic carbon electrode with a metallic backing as the anode. The LiFePO4 battery, also called the LFP battery, is a type of rechargeable battery. It is the safest Lithium battery type currently available on the market today. It is made to be small in size and light in weight, and the cycle life can reach thousands of cycles.

The difference between LiFePO4 batteries and other li-ion batteries

Inherited some advantages from Lithium-ion batteries

Large current charging and discharging are one of the advantages of LiPo batteries, which allows a device to release more energy in a short period of time.  These batteries are used more in racing and power tools: almost all drones and RC model batteries use lithium ion batteries. Batteries for RC models normally reach 15C, 30C, 50C discharge. Lithium-ion polymer batteries with high discharge rate can reach a maximum of 50C (continuous) and 150C (pulse). They are light in weight, have a long life, and can be manufactured into various shapes. These are just some of the advantages of lithium ion batteries, and lithium iron phosphate batteries have these advantages.

Long cycle life

Because a LFP battery’s cycle life is 4 to 5 times that of other lithium ion batteries, it can reach 2000 to 3000 cycles or more. The LiFePO4 battery can also reach 100% depth of discharge (DOD). This means that, for energy storage products, there is no need to worry about over discharging a LFP battery, and it can even be used for a longer period of time. A good LiFePO4 battery can be used for 3 to 7 years, so the average cost is very affordable. For more content on depth of discharge (DOD), you can read this article: What is DOD for LiFePO4 batteries? However, a LiFePO4 battery is not suitable for wearable devices as its energy density is lower than that of other lithium-ion batteries.  Furthermore, the battery compartment has limited space, so the capacity is relatively lower. Thus, compared to another LiPo battery, a LFP battery does not have quite as good endurance and compatibility with the conditions and internal space of wearable devices.

Why are most lithium iron phosphate batteries 12V?

It is said that the lithium iron phosphate battery can perfectly replace the lead-acid battery. The nominal voltage of a lead-acid battery is 2V, and the six lead-acid batteries connected in series are 12V. However, the 12V LiFePO4 battery pack is generally composed of 4 battery cells connected in series. The nominal voltage of a single lithium iron phosphate pouch cell is 3.2V.  When adding the voltage of the series, we get 12.8V (3.2V * 4 = 12.8V). There are also the 24V (25.6V) and 48V (51.2V), which are commonly used. In addition, the voltage requirement of most industrial applications is 12V or above, which is also the minimum standard of the nominal voltage of general industrial batteries. There are also many applications that need to reach 220V, even 380V or above, such as an industrial forklift, winch, electric drill, etc. The sales of 24V and 48V electric forklifts are on the rise especially recently, so a primary concern is over how safe a battery is. Compared to the lithium cobalt oxide and lithium manganese oxide batteries, lithium iron phosphate batteries are a lot more safe. The advantage of high life can reduce the whole costs of maintaining and replacing the battery as well.

The shortcomings of cold temperature

Compared to other LiPo and lead-acid batteries, lithium iron phosphate batteries have poor resistance in low-temperature environments; generally, they can only discharge at -10℃ to -20℃. However, clients think positively of LFP batteries and their high safety functions.  They sacrifice some battery performance and specify that they discharge at -30℃ to -40℃.  These batteries are mostly used in the military or deep sea and space equipment.
