Appliation of micro pumps in the new energy vehicle industry

In recent years, with high attention of countries around the world to new energy vehicles, many contries have taken measures: Italy, France, Sparin, the United States and other countyies have begun to clarify the ban on fuel cars. With the finalization of fuel vehicles for fuel vehicles in various countries, major car manufacturers in the world have also increased R & D investment from time to time, participationg in the competition of new energy vehicles, and formulated sales purposes, so as to seize the automobile market in this unprecedented opportunity.

Central components of new energy vehicles: battery three - in -one system. Power battery is the energy of electric vehicles. In the process of allowing me to allow me, the battery itself will generate a certain amount of heat, leading to increased temperature, which will affect many characteristic parameters of the battery, such as internal resisstance, voltage, SOC, available capacity, charging and discharge efficiency, and battery life. The problem of battery heat effects also affects the performance and cycle life of the vehicle. Therefore, good thermal management is very impotrant for battery performance and life.

Speaking of the battery thermal management system of new energy vehicles, it is necessary to mention the role of micro- pump(car electronic pump). At present, most of the new energy vehicles above the market use micro-pump(car electronic pump). At present, most of the new energy vehicles above the market use micro-pump(automobile electronic pump) cyclic coolant cooling battery pack to ensure the normal work of all electronic components.

Different applications of micro -pump(automotive electronic pump) are mainly divided into: car parking heater water pump, new energy vehicle cooling cycle pump,battery cooling and auxiliary heating cycle pump, liquid torque converter cooling cycle pump, new energy management system, explosion -proof electric vehicle pump, pure electric vehicle explosion -proof electric vehicle pump, pure electric vehicle explosion - proof command car pump, car turbochatger water -cooler cycle pump, parking heater circulation pump, preheating water pump, car cold device water circulation pump,car heating air conditioning cycle pump, The engine cooling circulation electron pump, pure electric bus and hybrid passenger car motor control the cooling circulation pump, the car battery refrigeration, motorcycle electric water pump, etc

As a source of power for cars, new energy vehicle power batteries are allowed to allow electrical heat to continue. The performance of power batteries is not closely related to returning temperature.

In order to extend the service life of the power battery as much as possible, the maximum power is botained, and the battery must be used within the specified temperature range. In the guidelines, the power battery unit is in the operating state within the range of -40 to 55 degress (actual temperature of the battery). Therefore, the new energy power battery crew is currently equipped with cooling equipment.

Power battery cooling system includes air -conditioning recyling cooling type and water -cooled breeze. The water -cooled poer battery cooling system uses a special coolant in the coolant pipe road outside the power battery, and transmits the heat generated by the power battery to the coolant. The heat generated by the coolant is taken away, and the coolant is pressed by the pump to complete the reciprocating cycle, thereby reducing the temperature of the power battery from time to time.
