Description

Technical Field

[0001] The present application relates to the technical field of ship batteries, and in particular to a ship battery insulation system. Background Art

[0002] In low temperature environments, the performance of batteries will be significantly affected. Specifically, low temperatures will reduce the activity of the battery, slowing down the chemical reaction rate inside the battery, resulting in a decrease in the battery's discharge capacity, a longer charging time, and difficulty in fully charging. In addition, the concentration of the electrolyte will increase and the diffusion coefficient will decrease at low temperatures, causing the charge transfer impedance inside the battery to increase significantly, affecting the normal operation of the battery. These problems are particularly prominent for ship batteries, as ships often need to operate in harsh marine environments, including cold winters.

[0003] In the existing technology, in order to solve these problems, engineers have developed battery preheating systems and thermal management systems. These systems use external heating and internal heating to quickly raise the battery temperature to the optimal operating temperature when the temperature is low. However, there are some problems with the existing battery preheating systems and thermal management systems. For example: although the electric heating system can effectively heat the battery, it will continue to consume electrical energy, resulting in energy waste; the heating system needs to be connected to the mains to heat and keep the battery warm, and the heating function cannot operate normally when the ship is at sea; the system cannot adaptively adjust the heater's on, off, and heating power according to the external environment, which will cause the battery to dissipate heat poorly when the ambient temperature is too high in summer. Summary of the invention

[0004] The present application provides a ship battery insulation system, which uses solar energy, wind energy or AC power supply to provide the energy required for heating and insulation of the battery, thereby avoiding damage to the battery cells caused by long-term low-temperature storage of the ship battery in winter and reducing energy waste.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In one embodiment of the present application, a ship battery insulation system is provided. Figure 1 As shown, including:

[0047] The heating module 100 includes a heater for generating heat and transferring the heat to the ship battery;

[0048] A power module 200, used to convert different forms of energy into input power of the heater through multiple circuits, wherein the energy includes solar energy, wind energy, city electricity and the energy of the ship's battery;

[0049] The temperature adjustment module 300 is used to adjust the heating temperature range of the battery according to external conditions, monitor the battery cell temperature and control the switch of the heater;

[0050] The control module 400 is used to identify external conditions, control the power module based on the external conditions, and switch the input power of the heater according to a preset threshold.

[0051] In specific implementation, the preconditions for using this system include: installing solar panels on the deck or appropriate location of the ship to collect solar energy and convert it into electrical energy. The solar panels convert direct current into alternating current through an inverter to provide energy for the heater; installing a small wind turbine on the ship to generate electricity using wind energy. The electrical energy generated by the wind turbine is also converted into alternating current through an inverter to supply the heater. There is a temperature sensor inside the ship's battery pack to monitor the temperature of the battery cell in real time and send it to the temperature regulation module.

[0052] The control module is specifically implemented in the following manner: by means of a computer or a device capable of signal processing, the current sunshine or wind value is collected, the relationship between the judgment value and the preset threshold is judged, and then the switch between the power module and the heater of the heating module is controlled based on the judgment result. The preset threshold is set based on the insulation requirements of the ship's battery. When external conditions such as sunshine or wind are suitable, solar energy or wind energy is used to power the heater, and the power of wind power generation or solar power generation can be adjusted in real time through the controller to avoid wasting battery energy or city electricity. When the wind or sunshine does not meet the heating power of the heater, the city electricity is used to supplement the power required for the heater to work. When the hull is not connected to the city power supply, or the wind and sunshine intensity does not meet the conditions, the battery energy is directly used to heat the battery cell.

[0053] The temperature regulating module collects data of external conditions, such as outdoor room temperature and light intensity, and collects data from temperature sensors inside the ship battery pack through a computer or a device capable of signal processing, to obtain the temperature of the battery cells, analyzes the temperature of the battery cells in combination with the data of external conditions, and controls the heater based on the analysis results.

[0054] The steps for using this system are:

[0055] S100: Initialize the system. When the ship is started or the battery insulation system is started, the system is initialized first. The temperature adjustment module reads the initial value of the temperature sensor, obtains the battery cell temperature of the ship battery, and presets the heating temperature range to determine the initial working state of the heater.

[0056] S200: Heating stage. When the battery temperature is lower than the preset heating temperature setting value, the temperature adjustment module controls the heater to start working. When the battery temperature reaches the preset heating temperature setting value, the temperature adjustment module stops the heater from working. At the same time, the control module intelligently adjusts the input power of the heater according to external conditions (such as sunshine intensity, wind force level, mains connection status) and the actual temperature of the battery.

[0057] S300: When the battery temperature reaches the preset heating temperature setting value, it enters the heat preservation stage. At this time, the temperature adjustment module intelligently adjusts the opening and closing of the heater according to the real-time feedback of the temperature sensor to keep the battery temperature within the preset heat preservation temperature range. During the heat preservation stage, the controller will regularly detect the battery temperature and adjust the heating power of the heater as needed.

[0058] In this embodiment, the beneficial effects include at least:

[0059] 1. The ship battery can be heated and insulated in a low temperature environment to maintain its normal operating temperature range, avoiding the loss of power grid and ship battery energy and extending the life of the ship battery.

[0060] 2. This application ensures the maximum utilization of energy through intelligent control strategies, by integrating multiple energy input methods, including city electricity, solar energy, and wind energy, and flexibly selecting input power sources according to different actual environments. For example, when there is sufficient sunshine or wind, the system can automatically switch to solar or wind power supply, reducing dependence on city electricity or battery energy.

[0061] Through data analysis and parameter adjustment of the control module, it adapts to the needs of various scenarios, achieves the optimal energy utilization effect, meets the heating needs of the battery under different working conditions, and improves energy utilization efficiency.

Existing battery heating systems often contain multiple complex components and connection points, which not only increases the complexity of the system, but also reduces the reliability and stability of the system.

[0073] In this embodiment, the connection mode of the components of the power module reduces the complexity of the system, facilitates the control by the control module, and is also easy to maintain.

[0074] In some embodiments, it also includes:

[0075] The human-computer interaction unit is used to provide an interactive screen for setting the heating temperature, viewing the battery temperature, or querying historical data.
