Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicles, and in particular relates to an oil-electric integrated modular storage battery heating device for heavy-duty wheeled vehicles.
[0002] The battery heating device provides heat by burning diesel. The heat generated by the combustion enters the battery installation box through the internal circulation air duct and heats the battery. The combustion exhaust gas is discharged to the outside of the vehicle through the exhaust pipe on the heating box. In order to avoid burns to people, the exhaust pipe is wrapped with an insulating sleeve.
[0003] By heating the battery, the temperature of the electrolyte inside the battery can be significantly increased, thereby restoring the battery's capacity and discharge capacity, ensuring the smooth start of the engine in a low temperature (extremely cold) environment. It can also significantly improve the battery's charging acceptance capacity, reserve sufficient energy for the next engine start, and keep the battery in the best working condition. Background Art
[0004] When heavy-duty wheeled vehicles encounter sudden drops in temperature in winter or long-distance cross-region maneuvers into cold areas, the battery capacity and charging and discharging capabilities are prone to decreases, causing the engine to fail to start normally.
[0005] Through the above analysis, the problems and defects of the prior art are as follows:
[0006] As an auxiliary power supply device, the battery of heavy-duty wheeled vehicles cooperates with the generator to supply power to the power-consuming device when the engine is not working or the output voltage is lower than the battery voltage, or when the output power of the generator cannot meet the needs of the power-consuming device. The battery must meet the engine's low-temperature starting performance requirements, and the low-temperature continuous discharge time must be no less than 1 minute. Tests have shown that for every 1 degree drop in ambient temperature, the battery power will drop by 0.8%, and the battery capacity and charge and discharge efficiency will also be greatly reduced, making it difficult to meet the engine's low-temperature starting requirements.
[0007] The existing battery heating solutions mainly include gas heating, liquid heating, solid heating, electric heating, etc. Gas heating is easy to arrange, consumes less energy, has a relatively simple structure, is highly versatile, and has low cost, and has better application prospects. Compared with liquid heating, gas heating has a simpler structure and is easy to arrange in the car; compared with solid phase change material heating, gas heating has higher thermal conductivity and shorter heating time; compared with electric heating, gas heating has lower power requirements and shorter preheating time. Therefore, gas heating devices are more conducive to quickly heating batteries in existing equipment. Utility Model Content
[0008] In view of the problems existing in the prior art, the utility model provides a modular oil-electric integrated battery heating device for heavy-duty wheeled vehicles to solve the problems mentioned in the background technology.
[0009] The utility model is realized in this way: a heavy-duty wheeled vehicle oil-electric integrated battery heating device comprises: a battery heating device, a battery installation box, and a heating control box.
[0010] The battery installation box places the battery inside, the battery heating device is connected to the battery installation box through an internal circulation air duct, the battery heating device is electrically connected to the heating control box, and the battery heating device and the heating control box are both connected to a power source.
[0011] Furthermore, the battery heating device includes a fuel tank, a battery heating box, and an exhaust pipe; the fuel tank is connected to the battery heating box; the battery heating box is connected to a heating control box and a battery installation box; the exhaust pipe is connected to the battery installation box and can be lengthened by a hose.
[0012] Furthermore, the battery installation box is provided with a circulating air duct and a battery temperature sensor inside, and the circulating air duct of the battery installation box is connected to the air supply pipe of the battery heating device.
[0013] Furthermore, the heating control box can automatically control the temperature in the heating box.
[0014] Furthermore, the smoke exhaust pipe is wrapped by a heat insulation sleeve.
[0015] First, the heavy-duty wheeled vehicle oil-electric integrated battery heating device provided by the utility model adopts diesel combustion to provide heat, heats the air to form a circulating heat flow, so as to quickly restore the capacity and discharge capacity of the battery, ensure the smooth start of the engine in a low temperature (extreme cold) environment, improve the battery charging and discharging capacity, and keep the battery in a good working condition.
[0016] Existing heavy-duty wheeled vehicles are prone to battery capacity and charge-discharge capacity decline when the temperature drops suddenly in winter, causing the engine to fail to start normally. Battery heating devices are usually divided into three types: water heating, electric heating, and gas heating. Water heating takes up a lot of space and has a complex structure, while electric heating consumes a lot of energy and is difficult to control the temperature. Gas heating is widely used because it consumes less energy and takes up less space.
[0017] The battery heating device, battery installation box, and heating control box are integrated into a design, and can be modularly embedded into the batteries of existing equipment, with the advantages of compact structure and easy installation and disassembly. The utility model provides a heavy-duty wheeled vehicle oil-electric integrated battery heating device. The heat generated by the combustion of diesel in the fuel tank enters the battery through the internal circulation air duct and heats the battery. The combustion exhaust gas is discharged to the outside of the vehicle through the exhaust pipe on the heating box, and the temperature can be increased by 1 degree per minute. In addition, to avoid burns to personnel, an insulating sleeve is installed on the exhaust pipe. It can effectively solve the problem of poor charging and discharging capacity of batteries under low-temperature conditions in low-temperature environments, and improve the low-temperature starting speed and success rate of the engine.
[0018] Second, the modular oil-electric integrated battery heating device has the advantages of small space occupation, controllable heating time, switchable heating and insulation, and low cost, which solves the contradiction between the small space of existing equipment and the complex structure of the heating device. The main protection of the structural scheme of the overall heating device, that is, the integrated design scheme of the battery heating device, the battery installation box, and the heating control box, as well as the integrated scheme of the fuel tank, the battery heating box, and the exhaust pipe included in the battery heating device. This scheme has the following advantages: it can achieve effective switching between rapid heating and insulation mode: ① The heating device quickly starts the heating mode, and the battery heating box has a high power design, so that the electrolyte temperature inside the battery rises rapidly, thereby quickly restoring the battery capacity and discharge capacity, ensuring the smooth start of the engine in a low temperature environment, and the heating time is designed to be within 25 minutes. ② In the insulation mode, the heating box runs at low power, the air outlet temperature is low, and it can continue to heat, so that the internal temperature of the battery gradually recovers from a low temperature state to a normal temperature state, and restores the original rated capacity of the battery. In this way, in the high-altitude and cold environment, you can first use the quick start heating mode to start the engine, and then switch to the insulation heating mode while the vehicle is driving to maintain the battery temperature, improve the battery's charging acceptance capacity, and reserve sufficient power for the battery's next use.
[0019] Third, as auxiliary evidence of the inventiveness of the claims of the utility model, it is also reflected in the following important aspects:
[0020] The expected benefits and commercial value after the technical solution of this utility model is transformed are:
[0021] The system can be used for rapid and low-cost transformation of existing heavy-duty wheeled vehicles. It has been applied to WZ551 and WZ523 wheeled armored vehicles, and has been trial-installed on heavy-duty trucks and tractors, effectively improving the starting performance of vehicles in extremely cold regions. It is of great significance to the performance improvement of heavy-duty special vehicles, and has obvious economic benefits.
[0022] (2) The technical solution of this utility model fills the technical gap in the industry at home and abroad:
[0023] Currently, there are few practical design solutions in this field at home and abroad, especially the installation solutions for wheeled special vehicles. The modular and small-volume heating device adopted in this solution fills the gap in practical solutions in this field.
[0024] (3) Whether the technical solution of the utility model solves the technical problem that people have been eager to solve but have never been able to solve successfully:
[0025] It effectively solves the problems of reduced discharge power and short duration of vehicle-mounted batteries in low-temperature environments, solves the problem of effective adaptation to existing batteries in a small space, and solves the problem of integrated control of battery starting and insulation.
