Batteries
In the Global Parts automotive store, you will find a wide selection of used car parts, compatible with brands such as Mercedes, BMW, Range Rover, and others.
Design and purpose of electric vehicle batteries
Electric vehicle batteries are energy storage assemblies, most commonly mounted in the vehicle floor or a dedicated section of the structural frame. Such a component consists of a housing, cell modules, high-voltage connections, sensors, and cooling and safety elements. The battery is used to power the electric motor and works in conjunction with the vehicle's electronics responsible for charging, temperature control, and monitoring operating parameters. This category includes components where it is important to compare the OEM number, replacement numbers, brand, condition, and compatibility with the vehicle version.
Comparison of electric vehicle battery variants
| Variant | Design | Application | What to check before selection |
|---|---|---|---|
| Complete traction battery | Housing, cell modules, connectors, mounting points, cooling system | Main energy storage in an electric vehicle | OEM number, connector layout, housing compatibility, vehicle version, and mounting location |
| Battery module | A pack of cells connected into a single working segment | Repair or rebuild of the set according to manufacturer specifications | Part number, module type, connection parameters, and compatibility with the main housing |
| Component with control equipment | Battery or its part with sensors and communication cables | Cooperation with vehicle operation monitoring and diagnostics | Connector type, presence of sensors, compatibility with installation and equipment |
Function of the traction battery and the importance of matching
The traction battery is used to store and release the energy required to drive an electric vehicle. Its correct matching affects not only the drive activation but also communication with the inverter, charging system, and cooling system. When selecting a part, it is worth considering the compatibility of the OEM number, body version, mounting points, and high-voltage connection type. A useful addition to the offer are also elements from the Traction batteries, BMS and cells category, when the repair involves more than one component.
BMS system and components working with the battery
The BMS system is an electronic circuit that monitors battery operation, reads module parameters, and controls charging and discharging safety. BMS stands for managing the pack status, communication with the vehicle, and reaction to voltage or temperature differences between sections. In practice, when selecting a part, the compatibility of not only the battery itself but also its cooperation with Battery Management Systems (BMS) and mounting accessories is important. For parts such as a traction battery, you should compare the OEM number, connector type, cooling method, and electronic equipment assigned to a given vehicle version.
Selection of electric vehicle batteries by vehicle version
The selection of such a component should take into account the mounting location, housing design, set completeness, and compatibility with the car's installation. When completing a repair for a specific model, e.g., BMW i3, it is worth checking the drive version, manufacturer designation, and connection method to the control system. When choosing an element such as a Mercedes EQC battery, the compatibility of mounting points, cooling system, and identification data assigned to the car also matters. For broader repairs, the Electric vehicle batteries and BMS category may be helpful, and as supplementary material, it is worth reading the article Steering play and leaks: is it worth buying a used steering rack from professional dismantling?.
FAQ
| Question | Answer |
|---|---|
| What is the design and purpose of electric vehicle batteries? | Electric vehicle batteries are energy storage assemblies for vehicle propulsion. A typical set consists of a housing, cell modules, electrical connections, sensors, and cooling and safety elements. Such a component is mounted in a specific place in the car's structure and must work with the high-voltage installation and vehicle control systems. |
| What are electric vehicle batteries used for? | Electric vehicle batteries are used to store and transfer the energy needed to drive the car. They are responsible for powering the traction system and cooperating with charging, recuperation, and control electronics. Without a correctly selected set, the vehicle may not operate properly, and communication with other components may be limited. |
| What is the design and function of the BMS system? | The BMS system is a circuit that monitors the operating parameters of the battery and its individual sections. It is responsible for reading voltages, temperatures, and communication with the vehicle, as well as controlling charging and discharging safety. In practice, it works with sensors, signal cables, and actuator electronics, which is why its compatibility with the battery is important when selecting parts. |
| How to choose a battery for an electric vehicle? | It is best to compare the OEM number, replacement numbers, vehicle brand, part condition, and equipment version. It is also worth checking the housing, connector type, cooling system, and mounting location. For parts from the secondary market, compatibility with the specific car configuration is also important. |
| What symptoms indicate a problem with the battery or its accessories? | Typical signals include communication errors, power limitation, charging problems, or incorrect operating parameter readings. The cause may be the battery itself, a module, cables, sensors, or a control element. Therefore, before purchasing, it is worth confirming which component requires replacement and which part number should be used. |
| What should be paid attention to during battery installation and compatibility? | Mounting points, housing completeness, compatibility with the installation, and the presence of accessories necessary for cooperation with the car are important. You should compare manufacturer designations, vehicle version, and equipment related to the high-voltage system. In the case of extensive repairs, you also need to check the cooperation with control modules and cooling elements. |
