🔋What is the energy storage battery pack?
The energy storage battery PACK—often called a battery module—is created by connecting multiple individual cells in series and parallel. But the process doesn’t stop there. Manufacturers also integrate mechanical structures, thermal management systems, and a Battery Management System (BMS) to form a complete and functional power unit.
When it comes to core technologies, PACK design emphasizes several critical aspects. These include overall structural strength, precision welding and process control, housing protection class, and the use of an active thermal management system.
Put simply, if you arrange two or more cells in series or parallel and assemble them into a custom shape based on a customer’s needs, what you get is a finished PACK.
⚡Composition of battery PACK
The important components of the battery PACK include the four parts of the single battery module, electrical system, thermal management system, box, and BMS.
▷ Battery Module
Think of the battery pack as the human body; the battery module acts as its “heart,” actively storing and releasing electrical energy to power the entire system.
▷ Electrical System
The electrical system forms the circulatory and nervous networks of the pack. It consists of connecting copper bars, high-voltage wiring harnesses, low-voltage wiring harnesses, and electrical protection devices. The high-voltage harness functions like an “artery,” continuously delivering power from the battery to the end load. Meanwhile, the low-voltage harness serves as a “neural network,” transmitting detection and control signals in real time.
▷ Enclosure
The enclosure—comprising the lower case, upper cover, metal brackets, panels, and mounting screws—provides structural integrity as the “skeleton” of the battery pack. It firmly supports all internal components, protects them against mechanical shock and vibration, and ensures reliable performance in diverse environments.
▷ BMS
The abbreviation of “Battery management system”, that is, the battery management system, can be compared to the “brain” of the battery. It is mainly responsible for measuring parameters such as voltage, current and temperature of the battery, as well as balancing and other functions. Data can be transferred to MES.
