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.

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.

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. 

What is Solar Energy?

Solar energy is an amazing and renewable power source that comes from the sun. This energy not only fuels life on Earth but also provides a clean and sustainable way to produce electricity. Did you know that in just one hour, the sun sends more energy to Earth than everyone on the planet uses in an entire year? We can capture and convert this energy into electricity using solar photovoltaic (PV) modules. "Photo" means light, and "voltaic" means electricity – so, PV modules turn light into electricity.

How Does Solar Energy Work and Why Should We Use It?

Solar PV modules work by absorbing sunlight and turning it into electrical current. This means that as long as the sun is shining, we can generate electricity almost anywhere. Plus, solar energy systems can include batteries to store energy, making them useful even in places far from the utility grid. Since solar panels have no moving parts, they require very little maintenance and can last over 25 years, providing reliable electricity for a long time. Unlike fossil fuels, solar energy doesn’t need to be mined, refined, or transported, making it a cleaner and more eco-friendly option.

The Growing Solar Industry

The solar industry is expanding rapidly, which means we are moving away from polluting and non-renewable energy sources. This growth also means a rising demand for skilled workers who can design and install PV systems.
