Classification of battery packs   What is battery pack?  (Battery cell,Battery,Battery pack) First of all, we must understand the general distinction between lithium battery cells, lithium battery modules and lithium battery packs: Battery cell: The most basic element that makes up a battery pack and a battery pack, generally the voltage that can be provided is between 3v-4v;   Battery: A collection of multiple cells to form a single physical module that provides higher voltage and capacity;   Battery pack: It is generally composed of multiple battery packs, and at the same time, a battery management system (bms) is also added, which is the final product provided by the battery factory to users.   Composition classification of battery pack: As the core component of PACK, batteries are currently divided into three main categories based on the shape of batteries: square shell, cylinder and soft pack (polymer battery). The positive and negative electrodes are packaged into the corresponding shells in different ways   Battery module By assembling single cells, the cells can be connected in series and parallel through bus bars, which can be locked by screws, resistance welding, ultrasonic welding, ultrasonic aluminum wire welding and laser welding. Considering the production yield, efficiency and the internal resistance of the connection point, laser welding is currently the first choice of many battery manufacturers.   Composition of battery pack It mainly includes battery module, mechanism system, electrical system, thermal management system and BMS.    Battery Module If the battery PACK is compared to a human body, then the module is the "heart", which is responsible for storing and releasing energy to provide power for the car.   Institutional system It is mainly composed of battery PACK cover, tray, various metal brackets, end plates and bolts, which can be regarded as the "skeleton" of battery PACK, which plays the role of support, mechanical shock resistance, mechanical vibration and environmental protection (waterproof and dustproof) effect.   Electrical System It is mainly composed of high-voltage jumpers or high-voltage wire harnesses, low-voltage wire harnesses and relays. The high-voltage wiring harness can be regarded as the "large artery" of the battery pack, which continuously transmits the power of the heart of the power battery system to various required components, and the low-voltage wiring harness can be regarded as the "neural network" of the battery pack, transmitting detection signals and control in real time Signal.   Thermal management system There are four main types of thermal management systems: air cooling, water cooling, liquid cooling, and phase change materials. Taking the water cooling system as an example, the thermal management system is mainly composed of cooling plates, cooling water pipes, heat insulation pads and heat conduction pads. The thermal management system is equivalent to installing an air conditioner for the battery pack.   BMS Battery management system The battery management system can be regarded as the "brain" of the battery. It is mainly composed of CMU and BMU.   CMU: Cell monitor Unit is a single monitoring unit, which is responsible for measuring parameters such as voltage, current and temperature of the battery, and also has functions such as equalization. When the CMU measures these data, it transmits the data to the BMU through the aforementioned battery "neural network".   BMU: Battery management Unit . Responsible for evaluating the data transmitted by the CMU. If the data is abnormal, it will protect the battery, issue a request to reduce the current, or cut off the charging and discharging path to prevent the battery from exceeding the permitted use conditions. At the same time, it also manages the power and temperature of the battery. According to the previously designed control strategy, judge the parameters and states that need to be warned, and send the warning to the vehicle controller, and finally convey it to the driver.   Process flow Battery PACK is the core energy source of new energy vehicles, providing driving power for the entire vehicle. As the core component of new energy vehicles, its quality directly determines the performance of the vehicle. Lithium battery manufacturing equipment is generally divided into three types: front-end equipment, middle-end equipment, and back-end equipment. The accuracy and automation level of the equipment will directly affect the production efficiency and consistency of the product. Although the types of batteries and modules are different, the composition and process flow of PACK are roughly the same (not all manufacturers have the same process flow)   PACK assembly process Mainly divided into assembly process, air tightness testing process, software writing process, electrical performance testing process, etc.   Production line introduction There are many flexible lines and press-fitting and tightening in the PACK assembly process. It is more difficult to automate and the input-output ratio is not high. Therefore, the automation degree of the rear-end equipment will be lower than that of the front-end and middle-end equipment, but it is compatible with cylindrical and square shells. , and soft pack three kinds of PACK battery pack assembly.   Stations that may require automation: -The lower housing is automatically on the line -Module automatically goes online into the housing -Module is fixed and screwed -The upper cover is threaded and tightened - Automatically apply A/B thermal paste (depending on the process) - Automatic sealant application (depending on the process) - Finished product off the assembly line   With the gradual maturity of the development of the power battery industry, the battery PACK modular technology will become more and more mature. The development of battery PACK technology involves multi-disciplinary and multi-field knowledge, and requires interdisciplinary technology integration. All in all, if car companies want to finally produce PACK products on a large scale that fully meet the requirements of new energy vehicles in terms of life, stability, reliability, and safety, they still need a lot of engineering practice and test verification, as well as continuous optimization and upgrading of products process.

  Portable Power Station (Portable energy storage outdoor power supply), core device lithium battery, first of all, fully consider the actual needs of indoor and outdoor in terms of volume, smaller size design, compared with traditional lead-acid batteries smaller and lighter, easy to use and carry. In terms of safety, energy saving and environmental protection, the traditional lead-acid battery is abandoned, no noise and no pollution, and has excellent safety performance. At the same time, many characteristics such as high storage energy density, large capacity, stable performance, and long cycle life have become the crystallization of wisdom under the development of modern manufacturing industry. And under the high-quality life, it can better meet the small household appliances used in home life to boil water and cook, and can also be used for power supply needs of daily consumer electronic products.   Points to choose outdoor power supply There are two main points to look at when purchasing an outdoor power supply: one is the capacity of the power supply (Wh watt-hour), and the other is the power supply (W watts). The capacity of the power supply determines the length of available power, the larger the capacity, the more power and the longer the use time. The power of the power supply determines the types of electrical appliances that can be used. For example, an outdoor power supply with a rated power of 1800W can drive electrical appliances below 1800W. At the same time, this formula (watt-hour ÷ power = available time of electrical appliances) can be used to calculate the available time of electrical appliances under different capacity power sources. Outdoor Power Usage Scenarios Now we have a certain understanding of the capacity and power of the power supply. Next, we can choose according to the number of users, electrical appliances, and usage scenarios. Scenarios for using outdoor power supplies can generally be divided into two types: leisure camping/self-driving travel, and their characteristics and requirements are summarized as follows: Leisure camping: 1-2 days of camping: the camping scene is to invite three or five friends to go camping on weekends. Estimated electrical equipment: mobile phones, speakers, projectors, cameras, Switches, electric fans, etc. Keywords: short distance, leisure, entertainment. Because the camping time is short (two days and one night), the demand for electricity is not strong, and it only needs to meet part of the entertainment, so it is recommended to choose a small-capacity power supply. Travel by car: If you choose to travel by car, you don’t have to be too strict about the weight of the power supply, but you are more concerned about the capacity/power of the power supply. Compared with leisure camping, self-driving travel has more time and more usage scenarios, including: car refrigerators, rice cookers, electric blankets, kettles, computers, projectors, drones, cameras and other high-power electrical appliances.  Charging method: At present, the mainstream charging methods include municipal electricity charging, car port charging and solar energy. In addition to the mains interface as a basic accessory, other charging methods may require the purchase of corresponding charging accessories. If you stay outdoors for a long time, it is still necessary to support the solar panel charging interface.ESUN also provide the optional solar panel for you to choose equip with the power station and charge anytime when you have a good solar condition.   Output Interface: Usually necessary are USB-A, Type-C, and AC output and DC interface. USB-A port, supports mobile devices. Type-C supports PD fast charging protocol devices such as mobile phones and notebooks to improve the charging efficiency of mobile devices. The AC interface provides AC 220V voltage and supports most electronic equipment such as sockets. The DC interface can provide car charger power supply or other devices that support 12V power supply.   Volume and weight:   Outdoor power supplies are generally made of lithium batteries. Outdoor power station require higher power and larger capacity, requiring more lithium batteries to be combined in series, thereby increasing the volume and weight of outdoor power supplies. When choosing an outdoor mobile power station, you can choose an outdoor power supply product with the same capacity and smaller weight and volume.   Capacity Zhceenergy have: 300W/650W/1000W/2000W/3000W/5000W  Please feel free to contact us for further question  

What is outdoor power supply (energy storage)?   Outdoor power supply is a kind of portable power station, which uses portable solar panels to charge the battery, and the stored electric energy can be used to charge or operate other devices. energy storage power supply. Outdoor power supplies are popular in outdoor camping, RV travel, outdoor live broadcast, outdoor construction, location shooting and emergency backup power supply. Equivalent to a small portable charging station, it has the characteristics of light weight, large capacity, high power, long life and strong stability. It can also output common power interfaces such as DC and AC, which can supply power for laptops, drones, photography lights, projectors, rice cookers, electric fans, kettles and other equipment.   What are the advantages compared with tradtional generators？ 1. Outdoor power supplies are less noisy. 2. Traditional generators run on fossil fuels, which contribute to air pollution and climate change. As an added bonus, you get solar power for free instead of expensive fossil fuels. 3. Easy to use as they require no oiling, refueling, starting and maintenance. Just turn it on, connect your device and draw power from it 4. Wear and tear on moving parts in emergency generators can lead to high maintenance costs. Solar generators have no moving parts and do not rely on natural gas to generate electricity. This design helps reduce the likelihood of paying for repairs. 5. Lighter than traditional gas generators, it's ideal for outdoor activities, camping, emergencies, and general mobility. Some of them even feature luggage-like pulls for enhanced portability.   We wanted to offer a variety of choices that will fit both your needs and your budget.     

Home energy storage consists of a battery that allows you to store surplus electricity for later consumption, and when combined with solar power generated by your photovoltaic system, the batteries allow you to store energy generated during the day for use around the clock. Since battery energy storage systems are capable of optimizing the use of electricity, they ensure the most effective operation of your home solar power system. At the same time, they also guarantee continuity in case of temporary disruptions in the power supply, with extremely low response times. Home energy storage further supports energy self-consumption: the surplus energy produced during the daytime from a renewable source can be stored locally to use at a later time, thus reducing the degree of dependency on the electricity grid. An energy storage battery therefore makes self-consumption more effective. Home battery storage systems can be included with a solar power system at installation, or added to an already existing system. Since they make solar power more reliable, these storage systems are becoming increasingly widespread as the falling prices and environmental advantages of solar power make it become an increasingly common alternative to traditional power generation.   How does a home battery energy storage system work? Lithium-ion battery systems, the most commonly used type, are made up of several parts: Battery cells, manufactured by battery suppliers and assembled in battery modules (the smallest unit of an integrated battery system). Battery racks, made up of connected modules that generate a DC current. These can be arranged in multiple racks. An inverter that converts a battery’s DC output to an AC output. A Battery Management System (BMS) controls the battery, and is usually integrated with factory-made battery modules. In general, solar power battery storage works like this: the solar panel is connected to a controller, which in turn is connected to the battery racks or banks where it is stored. When needed, the current from the battery must be passed through a small inverter, which transforms it from alternating current (AC) to direct current (DC), or vice versa. Then the current passes through a meter and is supplied to your chosen wall sockets. How much energy can a home battery energy storage system store? Energy storage power is measured in kilowatt hours (kWh). Battery capacity can range from as little as 1 kWh over 10 kWh. Most households opt for a battery with 10 kilowatt hours of storage capacity, which is the battery’s output when it is fully changed (minus a minimum charge that the battery needs to stay on). Considering the question of how much power does a battery store, most homeowners typically chose only their most important appliances to be connected to the battery, such as a refrigerator, a few sockets to charge phones, lights, and the wifi system. In the event of a total  blackout, power stored by a typical 10 kWh battery will last from 10 to 12 hours, depending what the battery is being asked to power. A 10 kWh battery can run a refrigerator for 14 hours, a television for 130 hours, or a single LED light bulb for 1,000 hours.   What are the benefits of home battery storage? Thanks to the home energy storage battery, you can increase the amount of self-produced energy you consume instead of consuming it from the energy grid. This is called self-consumption, meaning the capability of homes or businesses to generate their own power, and is an important concept in today’s energy transition. One of the advantages of self-consumption is that customers use the power grid only when they are not using their own self-generated power, allowing them to save on costs and avoid the risk of power outages. Energy independence from self-consumption or going off the grid means you are not reliant on a utility for your energy needs, and are therefore protected from price spikes, supply fluctuations and blackouts. If one of your main reasons for installing solar panels is to reduce carbon emissions, adding a battery to your system helps you get the maximum performance in terms of reducing your greenhouse gas emissions and your home’s carbon footprint. Home energy storage systems are also cost-effective, since you will be storing  power from a source of clean, renewable energy that is completely free: the sun. Zhceenergy supply professional solar battery solution.
