Cells >>> Battery PACK
* To assemble a battery module, a certain number of cells are connected in series and parallel.
* A complete battery pack, also known as a battery PACK, consists of a battery module, a thermal management system, a battery management system (BMS), and some structural components.
Battery Module
The battery PACK is responsible for storing and releasing energy to provide power for the car.
Mechanism System
The mechanism system mainly consists of the battery PACK cover, tray, various metal brackets, end plates and bolts. It can be regarded as the skeleton of the battery PACK, which plays the roles of support, resistance to mechanical impact, mechanical vibration and environmental protection (waterproof and dustproof).
Electrical System
The electrical system mainly consists of high-voltage jumper or high-voltage wiring harness, low-voltage wiring harness and relays. The high-voltage harness can be regarded as the artery and blood vessel of the battery PACK and it can continuously deliver the power from the heart of the power battery system to each required component. The low-voltage harness can be regarded as the neural network of the battery PACK, which transmits detection and control signals in real time.
Thermal Management System
There are four main types of thermal management systems: air-cooled, water-cooled, liquid-cooled, and phase change materials. Taking the water-cooled system as an example, the thermal management system mainly consists of cooling plate, cooling water pipe, heat-insulating pad and heat-conducting pad. The thermal management system can be regarded as the air conditioner of the battery pack.
BMS Battery Management System
The battery management system, which can be regarded as the brain of the battery, is mainly composed of CMU and BMU.
Battery PACK-Thermal Conductive Material Solutions
The application of thermally conductive materials in the field of new energy vehicles is a crucial technological advancement that plays a key role in improving the performance, safety and efficiency of vehicles. With the increasing global awareness of sustainable energy and environmental protection, the demand for new energy vehicles is growing rapidly. Against this background, the application of thermally conductive materials has become an important aspect of enhancing the performance of new energy vehicles.
Thermally conductive materials are a class of materials that can effectively transfer heat energy, and they play a role in several key areas in new energy vehicles. In battery PACK, thermally conductive materials can regulate the temperature of the battery to ensure that battery operates at the optimal operating temperature and prevent overheating. It extends battery life and increases energy density and charge/discharge efficiency. Therefore, it is crucial for battery safety.
