Description

Battery Constant Temperature Control Structure for Electric Vehicles Technical Field

[0001] This creation relates to a battery constant temperature control structure for electric vehicles that can manage the temperature of the batteries of electric bicycles. Prior Art

[0002] Electric bicycles have environmental protection characteristics such as low pollution, low carbon emissions, and low noise. They can use the most easily obtainable electricity to replace limited petroleum, reduce the impact of carbon dioxide on the earth, and mitigate the climate change brought by greenhouse gases. In addition, the electric bicycle industry can also drive the supply of related spare parts and the input of related human resources to increase the overall employment market. Therefore, governments of all countries are happy to see the booming development of this industry and hope to use electric bicycles to suppress the use of cars and motorcycles.

[0003] However, in a low-temperature environment, it will cause an increase in the viscosity of the electrolyte of the battery of an electric bicycle and a slowdown in the ion migration speed, resulting in significant decreases in the cruising range (about 20%-40%) and charging speed. This is because a cold environment will increase the internal resistance of the battery and reduce the discharge efficiency. Therefore, how to make the battery of an electric bicycle reach a constant temperature state to greatly extend the cruising range of the electric bicycle is the problem that the creator wants to improve.

[0004] Therefore, in view of this, the creator had the idea of creation, and then designed it with many years of experience, explored and made sample tests in many ways, and after many corrections and improvements, this creation was launched. Summary of the Invention Problems to be Solved by the Invention

[0005] Means for Solving the Problems

[0006]

[0007] The present creation provides a battery constant temperature control structure for an electric vehicle, which includes: an electric bicycle and a battery unit. Among them, the electric bicycle has a vehicle frame, two wheel bodies, an assist motor and two pedals. Fork parts are formed at the front and rear of the vehicle frame. A wheel axle is provided in the center of the wheel body, and the fork parts are used to pivotally connect the wheel axle, so that the wheel body can be positioned on the vehicle frame in a rotatable manner. The assist motor is provided on one of the wheel bodies and is electrically connected to the battery unit installed on the vehicle frame. By providing the power required for the operation of the assist motor by the battery unit, the electric bicycle can use the assist motor to provide auxiliary output during the riding process of pedaling, and at the same time, it can also recharge the battery unit through the power generation of the assist motor. The battery unit has a battery seat, a battery pack and a battery box. The battery seat is fixed on the vehicle frame of the electric bicycle. The battery pack is accommodated inside the battery box. A charging hole is reserved on the battery box. The battery box is detachably arranged on the battery seat, so that the battery box together with the battery pack can be removed from the battery seat, and the battery pack can be charged by connecting a power source through the charging hole. Each side surface of the battery pack is provided with a constant temperature ceramic sheet. The power consumption of the constant temperature ceramic sheet is taken from the battery pack. By using the constant temperature ceramic sheet for temperature management, when the temperature of the battery pack drops to a certain temperature, the battery pack can be maintained at an ideal working temperature through the heat generated by the constant temperature ceramic sheet. Thus, a battery constant temperature control structure for an electric vehicle can be obtained. Effect of the Invention

The wheel (12) has an axle (121) in the center. The fork (111) provides a pivot for the axle (121), allowing the wheel (12) to be rotatably positioned. The frame (11) and the power assist motor (13) are mounted on a wheel (12) and electrically connected to the battery unit (20) mounted on the frame (11). The battery unit (20) provides the power required for the power assist motor (13) to operate, allowing the electric bicycle (10) to use the power assist motor (13) to provide auxiliary power during the pedaling process (14). At the same time, the power generated by the power assist motor (13) can also recharge the battery unit (20). The battery unit (20) has a battery holder (21), a battery pack (22), and a battery box (23). The battery holder (21) is fixed to the frame (11) of the electric bicycle (10). The battery pack (22) is housed inside the battery box (23). The battery box (23) has a pre-drilled charging port (231). By detachably mounting the battery box (23) on the battery holder (21), the battery box (23) together with the battery pack (22) can be removed from the battery holder. (21) Remove the battery pack (22) from the top so that it can be connected to the power source (mains power) through the charging port (231) to charge the battery pack (22). Each side surface (outer surface) of the battery pack (22) is provided with a thermostatic ceramic plate (24). The power of the thermostatic ceramic plate (24) is taken from the battery pack (22).
