Description
Technical Field
The invention belongs to the technical field of electric automobile application, and particularly relates to an electric automobile cold start system based on eddy current heating.
Background
With the rapid development of the field of electric automobiles, the technology of the electric automobiles is mature day by day at present, and the electric automobiles relying on traditional energy sources are gradually replaced, so that the electric automobiles need to normally run in more extreme application scenes, and when the electric automobiles are subjected to cold start at the environmental temperature of-20 ℃ to-30 ℃, the electrolyte viscosity is increased due to low temperature, the ionic activity is reduced, the internal resistance is increased, the endurance mileage of the electric automobiles is rapidly reduced, the batteries are easily over-discharged, and the irreversible damage of the power batteries is further caused. Therefore, the selection of a high-efficiency and reliable battery cold start system is crucial to the improvement of the reliability of the electric automobile under extreme conditions and the guarantee of the efficient operation of the electric automobile.
The heating mode that electric automobile cold start system mainly adopted at present does: electric heating, heat pump heating, alternating current charging and discharging preheating and other heating modes. For example, in the patent of "a low temperature resistant lithium battery pack for electric vehicle" (patent number: 202020421061.6), zhui group heats air by using an electric heating pipe when the temperature of the battery pack is low, the heated air preheats the battery pack, the influence of too high or too low working temperature of the battery pack on the battery pack is effectively avoided by designing the battery pack, and the working efficiency of the battery pack is improved.
For example, in the "integrated indirect heat pump vehicle heating management system for electric vehicle" patent (patent No. 201922014228.7) of dow et al, the temperature of the battery pack is raised to a temperature suitable for operation by heating the low-temperature battery pack with a heat pump for dehumidification and heating of the passenger compartment of the electric vehicle. Through utilizing passenger cabin heat pump to heat the group battery, the inside subassembly of electric automobile has been utilized to the efficient, has simplified the inside cold start system structure of electric automobile greatly, promotes the work efficiency of electric automobile group battery.
For example, in the patent of "a power battery charger using ac charging and discharging to preheat quickly" (patent No. 201410010053.1), weichi et al, the dc of a battery pack is converted into high-frequency alternating current by using an electric control system, and the battery is charged and discharged by using the alternating current, so that heat is generated from the inside of the battery, the uniformity of the temperature of the battery pack is improved, the structure of a cold start system is greatly simplified, and the efficiency of the battery pack is improved.
However, the conventional cold start system of the electric vehicle has some defects, the battery can be heated only by electric heating in a heat conduction mode, and the internal temperature of the battery is not uniform, so that the internal thermal stress of the battery is caused. The heat pump heats the battery pack through heating air, and a heat pump system is too large, so that the structure simplification and the weight reduction of the electric automobile are not facilitated. Alternating current charging and discharging preheats and utilizes alternating current to charge and discharge the battery, and such a heating mode needs complicated electric control equipment, and because monomer difference exists between batteries, the system design is more complicated, and the reliability is lower.
In view of the defects of the cold start systems of the electric automobiles, the invention provides the cold start system of the electric automobile based on eddy current heating. The temperature fields of all parts of the square battery monomer are uniform, the heating speed is high, the heating efficiency is high, and the system structure is simple and reliable.
