Description

Technical Field

[0001] This invention belongs to the field of vehicle engineering technology, and particularly relates to a braking heat recovery system, vehicle, control method, electronic equipment, and storage medium. Background Technology

[0002] In harsh winters, the performance of the power batteries in new energy vehicles degrades significantly due to low ambient temperatures, resulting in a substantial reduction in their effective driving range. Simultaneously, due to their high weight and heavy load, new energy vehicles generate significant heat in their braking systems (especially between the friction pads and brake drums / discs) during long downhill slopes or frequent braking. If this heat is not properly managed, it will cause a rapid increase in brake temperature, leading to brake fade and seriously threatening driving safety.

[0003] Currently, to address the issue of low-temperature batteries, the industry generally employs active thermal management systems, which use heating elements such as positive temperature coefficient (PTC) heaters to heat the battery. However, PTC heaters are themselves high-energy-consuming components in the vehicle, consuming a significant amount of the battery's electrical energy during operation, thus further exacerbating the reduction in driving range during winter. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a braking heat recovery system, vehicle, control method, electronic equipment, and storage medium, which can recover the frictional waste heat generated by the braking system and use it for heating the power battery. This not only effectively reduces the heating energy consumption of the battery in low-temperature environments and directly improves the vehicle's driving range, but also enhances the reliability and safety of the braking system through active cooling.

[0005] This invention is implemented by providing a braking heat recovery system, comprising: A brake, the brake including a brake disc with a heat exchange coil embedded in the brake disc for absorbing the heat generated by the friction pads; The power battery has a heat exchange plate installed inside its battery pack, and the heat exchange plate is connected to the heat exchange coil via a pipeline. The system includes a controller, a pump body, and a valve assembly installed on the pipeline. The pump body drives the coolant to circulate in the system, and the controller is used to respond to temperature signals and control the pump body and valve assembly according to preset logic.

[0006] Furthermore, the heat exchange plate has an S-shaped structure and is closely fitted to each battery cell.

[0007] Furthermore, the control unit also includes a brake temperature sensor for monitoring the temperature of the friction pads, a coolant temperature sensor for monitoring the temperature of the coolant entering and leaving the brake, and a power battery temperature sensor for monitoring the battery temperature. The brake temperature sensor, coolant temperature sensor, and power battery temperature sensor are all communicatively connected to the controller.

[0008] Furthermore, it also includes a backup cooling unit, which allows the valve assembly to direct coolant to the backup cooling unit when the power battery does not require heating.

[0009] Furthermore, an annular groove is formed on the brake disc, and the heat exchange coil is made of copper and is arranged in a spiral disc within the annular groove of the brake disc.

[0010] On the other hand, a vehicle is provided that includes any of the braking heat recovery systems described above.

[0011] Another aspect provides a control method for controlling the braking heat recovery system described in any one of the claims, the method comprising: Continuously monitor brake temperature and power battery temperature; Compare the real-time temperature data with a preset threshold. Once the startup conditions are met, the heat recovery system is started. The controller starts the pump and opens the valve group to allow the coolant after heat exchange through the heat exchange coil to flow to the heat exchange plate. At the same time, the pump flow rate is adjusted to match the heat transfer requirements. When the power battery temperature reaches the preset threshold, the valve assembly directs the coolant to the backup cooling unit.

[0012] Furthermore, when the brake temperature is below a preset threshold, the controller stops the pump from operating.

[0013] Another aspect provides an electronic device, comprising: At least one processor; A memory that is communicatively connected to the at least one processor; The memory stores a computer program that can be executed by the at least one processor, and the at least one processor implements the control method when executing the computer program.

[0014] Another aspect provides a non-volatile readable storage medium on which a computer program is stored, which, when executed, implements the control method described above.

[0015] The advantages and technical effects of this invention are as follows: By adopting the above technical solution, the frictional waste heat generated by the braking system is recovered and used for heating the power battery, which not only effectively reduces the heating energy consumption of the battery in low-temperature environments and directly improves the vehicle's driving range, but also enhances the reliability and safety of the braking system through active cooling. At the same time, this integrated design optimizes the energy utilization efficiency of the whole vehicle and improves the overall performance and adaptability of the vehicle in harsh conditions such as cold regions and mountainous areas.
