The electronic water pump is a new type of water pump that uses piezoelectric materials as the power device, completely realizes electronicization from control to drive, and completely controls the liquid transmission with the electronic integrated system, so as to realize the adjustability and accuracy of the liquid transmission.
The electronic water pump is divided by power, the higher the power, the greater the technical difficulty, 18W belongs to the low power, which is used for the cooling of superchargers, etc., mainly used for fuel vehicles; 30-100W is mostly used for cooling air conditioners, motors, batteries, etc. of new energy vehicles; More than 200W is mostly used for fuel vehicle owners, water pumps, fuel cells, etc.
At present, the technical difficulty and high barriers are 200W-1500W level electronic water pumps, and high-power electronic water pumps are used in domestic fuel cell cooling pumps and fuel vehicle main pumps, which have higher profit margins. In 2021, China produced 21.408 million passenger cars, including 3.545 million new energy vehicles and 17.863 million gasoline vehicles. Domestic automobiles mainly use Germany's turbocharging technology, 50% of automobile engines use turbocharging technology, in order to achieve fuel consumption reduction, 70% of cars using turbocharging technology adopt electronic water pump production technology. In 2021, the demand for electronic water pumps for traditional fuel vehicles in China will be about 6 million units.
In the new energy vehicle market, new energy vehicles need to carry out accurate temperature control of the three-electric system, in the case of water cooling, each vehicle needs 2-5 electronic water pumps (about 3 on average), and it is expected that by 2025, the market size of new energy vehicle electronic water pumps will reach 3.50 billion yuan.
