The invention discloses a high-power system integration method, which comprises the following steps of: 1, analyzing the power of a power supply system; 2, analyzing the capacity of the power supply system; 3, constructing a power supply system; 4, constructing a thermal management system; 5, integrating the system; 6, carrying out simulation optimization. Compared with an existing high-power lithium ion battery system, the high-power lithium ion battery system has the advantages that the power and the capacity of a required battery are analyzed, functional modules of the battery system are integrated into a power management system and a power protection system, the integration degree of the system is improved and functional redundancy is reduced. A temperature control function is realized by integrating a thermal management system, so that the environment temperature of the battery can be automatically adjusted to the optimum temperature; the performance of the battery is prevented from being influenced by temperature change, the stability of the integrated system can be tested by carrying out analog simulation on the designed system, the system is optimized according to the stability, and the later maintenance is reduced.

Description

technical field [0001] The invention relates to the technical field of high-power system integration, in particular to a high-power system integration method. Background technique [0002] A high-power lithium-ion battery system is a system used for lithium-ion battery management. It generally has self-test functions, battery parameter detection functions, insulation detection functions, early warning functions, charge and discharge management functions, etc. There are strong functions among these functions. However, the integration level of the functional modules of the existing lithium-ion battery system is low, which leads to unreasonable system architecture design, resulting in redundant functions and inconvenient maintenance in the later period. The existing battery protection system can only detect the battery temperature through the temperature detection module, and then give an early warning. The system lacks a temperature control function and cannot automatically ad...

[0002] A high-power lithium-ion battery system is a system used for lithium-ion battery management. It generally has self-test functions, battery parameter detection functions, insulation detection functions, early warning functions, charge and discharge management functions, etc. There are strong functions among these functions. However, the integration level of the functional modules of the existing lithium-ion battery system is low, which leads to unreasonable system architecture design, resulting in redundant functions and inconvenient maintenance in the later period.

The existing battery protection system can only detect the battery temperature through the temperature detection module, and then give an early warning. The system lacks a temperature control function and cannot automatically adjust the battery ambient temperature to the optimum temperature, which is not conducive to battery protection and is likely to cause safety hazards due to high temperature , or affect battery performance due to low temperature
