The thermal management of new energy vehicles is not only related to the comfort and safety of driving, but also the key to ensure the safety of battery system, improve the low temperature performance of batteries, reduce the power consumption of the whole vehicle, and achieve the standard rate of vehicle life.
It is one of the key factors for the sustainable development of the new energy vehicle industry.
Compared with the traditional thermal management of fuel vehicles, the value of the core components of the thermal management system of new energy vehicles has been greatly increased (2-3 times).
In 2023, the sales of new energy vehicles in China reached 9.
495 million, an increase of 37.
9% over the same period last year.
The fast-growing new energy market provides a huge market space for thermal management of new energy vehicles.
Based on this background, Gaishi Automotive Research Institute studies and analyzes the new energy passenger vehicle thermal management industry from the industry overview, industry development status and development trend of new energy passenger vehicle thermal management.
The part of the report is as follows: the core components such as battery and motor electric control are highly sensitive to temperature and must be at an appropriate temperature in order to achieve efficient and stable output.
In recent years, the frequent thermal runaway incidents of new energy vehicles make consumers pay more and more attention to the safety of new energy vehicles.
How to do a good job of vehicle thermal management of new energy vehicles has become the focus of industry research.
Compared with the traditional thermal management of fuel vehicles, the thermal management system of new energy vehicles is more complex, with the addition of high-value components such as electric compressors, battery cold plates, Chiller and solenoid valves, and the overall cost of the system increases greatly, which brings a huge development space for the thermal management market of new energy vehicles.
With the cross-border entry of the traditional white goods giants represented by Midea, Gree and Hisense, the competition in the thermal management market of new energy vehicles is becoming increasingly fierce, and the market pattern is also changing.
At present, Denso, Mahler, Hanang and other international head suppliers, based on their relatively perfect product layout and market first-mover advantages, expand to integrated solution providers with a longer value chain.
Top, Sanhua, Silver Wheel and other enterprises have a certain competitive advantage in the field of some single parts, through mergers and acquisitions and technology research and development, continue to expand and improve their product line layout, and move forward to system integrators.
Midea, Hisense, Gree and other new players, on the other hand, rely on their own technology accumulation in the field of household air conditioning to enter the core parts market of thermal management.
As the automobile industry moves towards the direction of electrification and intelligence, the complexity of vehicle energy management is gradually increasing, and the requirements for automobile energy management system are also increasing.
In order to maximize the use of vehicle heat and reduce vehicle energy consumption, integrated thermal management has become the choice of more and more automobile enterprises.
Through the reasonable distribution of vehicle heat, the contradictory phenomenon of “heat dissipation from the outside and power consumption at the same time” can be avoided.
With the increasingly stringent environmental laws and regulations, the search for new clean and environment-friendly refrigerant alternatives has become the focus of industry research.
The natural refrigerant R744 (CO2), which takes into account safety, environmental protection and performance, is expected to become one of the alternative routes for the next generation of automotive refrigerants.
Through all kinds of sensors to sense the occupant information in the cockpit (including position, sex, age, clothing index, etc.
), with the blessing of the intelligent algorithm, through the temperature control devices arranged in the door panels, seats, headrests and other parts, to create a local comfortable micro-environment with occupants as the center, and provide passengers with a more energy-saving, comfortable and intelligent driving experience, which can not only improve the comfort of passengers.
At the same time, the energy consumption of cabin thermal management can be greatly reduced.
