In the fields of electric vehicles and hybrid vehicles, the design of 800V (high voltage range of about 600-900V) battery pack is very important. This article will discuss the complete design requirements list of 800V battery pack, and focus on the important points of electrical, thermal management, machinery, functional safety, testing/regulations, manufacturing and maintenance.

I. Electrical design requirements and key points

1. battery Module selection: select battery modules that meet the requirements of 800V high voltage to ensure the matching and stability between modules.
2. Battery Management System (BMS) design: a high-performance BMS system is designed to realize real-time monitoring and management of battery pack of voltage, temperature, current and other parameters.
3. Charge and discharge management: ensure that battery pack has appropriate charge and discharge control strategies to avoid safety problems such as overcharge or overdischarge.
4. Electrical connection design: Design reasonable electrical connection mode, reduce resistance, reduce heat loss, and ensure efficient transmission of electric energy.

II. Description of thermal management design requirements and key points

1. heat dissipation design: design an effective heat dissipation system to ensure that battery pack can maintain appropriate working temperature under high-pressure working conditions.
2. Temperature Monitoring and Control: set a temperature sensor to monitor the temperature of battery pack in real time and take measures to control the temperature within a safe range.

III. Mechanical design requirements and key points

1. structural design: designed solid and stable battery pack structure to ensure that no deformation or damage occurs while the vehicle is running.
2. Installation method: select an appropriate installation method to ensure the safety of battery pack is fixed on the vehicle to avoid vibration or displacement during driving.
3. Protective measures: design effective protective measures to prevent external objects from causing damage or short circuit to battery pack.

IV. Functional safety design requirements and key points

1. safety standards: ensure that the design of battery pack meets relevant functional safety standards, such as ISO 26262.
2. Fault Diagnosis: design a fault diagnosis system, find battery pack faults in time and take corresponding countermeasures.
3. Safety isolation: design a safety isolation system to ensure that the connection between battery pack and other systems can be cut off in time in case of failure.

V. Test/regulatory design requirements and key points

1. test standards: ensure that battery pack of the design meets relevant test standards, such as electromagnetic compatibility testing and safety testing.
2. Compliance with regulatory requirements: ensure that the design of battery pack complies with local regulations and standards, and ensure the legal operation of vehicles under regulatory requirements.

VI. Description of manufacturing and maintenance design requirements and key points

1. manufacturing Process Specification: formulate strict manufacturing process to ensure that battery pack of the production process meets the quality requirements.
2. Maintenance convenience: design a battery pack structure that is easy to disassemble and repair, reducing maintenance costs and maintenance time.

800V battery pack the list of design requirements covers electrical, thermal management, machinery, functional safety, testing/regulations, manufacturing and maintenance, etc. Only by comprehensively considering these key points and ensuring that the design of each link meets relevant requirements can Battery pack be guaranteed to work under high pressure.
