Description

SPECIFICATION
LU601 229
A thermal management system for new energy vessel batteries
Technical Field
The present invention relates to the technical field of new energy vessel power batteries, specifically to a thermal management system for new energy marine battery systems.
Background
New energy vessels for maritime and inland waterways are pivotal in advancing the marine industry toward high-end, intelligent, and eco-friendly development, serving as a critical component in achieving green, low-carbon, and high-quality growth. Lithium-ion batteries, known for their long cycle life, high specific energy, and absence of memory effects, have been widely adopted as power supply units in new energy vessels. However, due to the low capacity and voltage of individual battery cells, large-scale battery arrays are required to meet the endurance and power demands of vessels. Space constraints necessitate dense arrangement of numerous lithium batteries within the ship hull.
On one hand, when operating in high-temperature environments, the heat generated by lithium-ion batteries is difficult to dissipate, increasing the risk of thermal runaway. On the other hand, during operation in low-temperature environments, the charge-discharge voltage of the battery decreases, leading to a severe decline in performance.
During the charging and discharging process, marine power batteries produce a significant amount of waste heat. If not dissipated in time, this can result in temperature imbalance within the battery pack, shortened cycle life, or even thermal runaway. Traditional solutions often rely on forced air cooling or liquid cooling for passive heat dissipation, where the waste heat is directly discharged into the environment without being recycled, leading to energy waste.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the
SPECIFICATION aforementioned technical shortcomings and provide a thermal management system for 10001689 new energy ship batteries that facilitates energy recovery and utilization.
To address the above technical problem, the technical solution provided by the invention 1s as follows: À thermal management system for new energy ship batteries, comprising a temperature monitoring module, a cooling module, a control module, a heat storage module, a thermal phase-change power generation module, and a thermoelectric generation controller.
The temperature monitoring module is connected to and installed within the ship's battery for temperature monitoring, while the cooling module is partitionally arranged on the outer side of the ship's battery. The cooling module exchanges heat with the heat storage module, and the heat storage module provides a heat source to the thermal phase-change power generation module, with thermoelectric power generation controlled by the thermoelectric generation controller.
Preferably, the thermal phase-change power generation module includes TEG (thermoelectric generator) sheets connected in a series-parallel hybrid topology, with thermal conductive grease filled between the cold end and the liquid cooling plate.
Preferably, the temperature monitoring module comprises a fiber optic sensor array and an infrared thermal imaging unit to acquire real-time temperature field distribution on the battery surface and inside the battery.
Preferably, the cooling module is partitionally configured with a liquid cooling submodule and an air cooling submodule. The liquid cooling submodule employs an anti-corrosion microchannel structure for its cooling plates, while the air cooling submodule is equipped with hydrophobic airflow channels.
Preferably, the thermoelectric generation controller is connected to the ship's energy management system.
Preferably, the heat storage module features adjustable phase-change temperatures, including 45°C and 55°C, with insulation plates arranged between adjacent zones of the module.
Compared to existing technologies, the advantages of the present invention are as follows: In this invention, the coordinated operation of the cooling module and the 6
SPECIFICATION heat storage module facilitates efficient heat recovery. Meanwhile, the thermal 10001689 phase-change power generation module and the thermoelectric generation controller enable thermoelectric power generation based on thermal energy, thereby enhancing the vessel's endurance. Additionally, the thermal conductive grease filled between the cold end and the liquid cooling plate ensures stable temperature differentials.
Brief Description of the drawings
FIG. 1 1s a schematic structural diagram of the present invention.
Description of Embodiments
The present invention will now be described in further detail with reference to the accompanying drawings.
Combined with the attached Figure 1, a thermal management system for new energy ship batteries comprises a temperature monitoring module, a cooling module, a control module, a heat storage module, a thermal phase change power generation module, and a thermoelectric generation controller. The temperature monitoring module is connected to and arranged inside the ship battery for temperature monitoring, while the cooling module is partitionally disposed on the outer side of the ship battery. The cooling module performs heat exchange with the heat storage module, and the heat storage module provides a heat source to the thermal phase change power generation module, with thermoelectric generation being controlled by the thermoelectric generation controller.
During specific implementation of the present invention, the thermoelectric power generation module includes TEG sheets connected in a series-parallel hybrid topology, with thermal grease filled between the cold end and the liquid cooling plate.
The temperature monitoring module comprises an optical fiber sensor array and an infrared thermal imaging unit to acquire real-time temperature field distribution on the battery surface and inside the battery. The cooling module is divided into zones with liquid-cooling submodules and air-cooling submodules. The liquid-cooling submodules adopt anti-corrosion microchannel structures for the liquid cooling plates, while the air-cooling submodules are equipped with hydrophobic airflow guide 7
SPECIFICATION channels. 7601229
When in use, the thermoelectric generation controller is connected to the ship's energy management system, and the phase change temperature of the thermal storage module is adjustable, including 45°C and 55°C. Thermal insulation plates are arranged between adjacent areas of the thermal storage module.
The specific phase change temperatures are: 45°C for the lithium ternary battery region and 55°C for the lithium iron phosphate battery region.
The fiber optic sensor array is arranged along the gaps of the battery module with an accuracy of +0.5°C and a sampling frequency of 10 Hz. The infrared thermal imaging unit is installed on the top of the battery compartment, featuring a scanning resolution of 1°C/pixel, and is capable of identifying local hot spots (triggering an early warning when the temperature rise rate exceeds 2°C/s).
The liquid cooling plate is made of anodized aluminum 6063, with microchannels having a width of 0.8 mm. The coolant consists of an ethylene glycol/nano-alumina composite fluid, the flow of which is regulated by a PID controller based on real-time battery temperature feedback.
The air diversion duct has its inner walls coated with polytetrafluoroethylene (PTFE) to prevent condensation buildup.
Thermal Storage Module and Thermoelectric Power Generation Module:
PCM Encapsulation. A phase change material (PCM) comprising a paraffin/expanded graphite composite (mass ratio 8:2) is encapsulated within a honeycomb aluminum framework having a porosity of 85% and a thermal conductivity of =5 W/m * K.
TEG Arrangement: For every six battery cells, 16 thermoelectric generators (TEGs) (40X40 mm each) are arranged in a series-parallel hybrid configuration to minimize internal resistance, with a maximum output power of 80W per module.
Thermal grease is applied between the cold side of the TEGs and the liquid cooling plate to maintain a stable temperature gradient.
When the battery temperature is between 35-45°C, the TEG operates at full power, with electrical energy prioritized to supply the BMS. If a thermal runaway risk is 8
SPECIFICATION detected (temperature rise rate > 3°C/s), the TEG circuit is cut off and the liquid 10001689 cooling system is activated at maximum speed for heat dissipation. When the ambient temperature is below 5°C, the TEG is electrified in reverse (utilizing the Peltier effect), with the cold end heating the battery to 10°C. The system communicates with the ship's EMS via CAN bus and supports both islanded operation and grid-connected switching.
The PCM honeycomb support is inserted into the intercell gaps of the battery module to ensure intimate contact with the battery surfaces. The TEG (thermoelectric generator) sheets are affixed between the PCM layer and the liquid cooling plate via thermally conductive adhesive, wherein every six battery cells constitute one power generation unit.
