Description

Technical Field

[0001] The utility model relates to the technical field of battery control for new energy electric ships, and in particular to a battery compartment constant temperature control system for new energy ships and the new energy ships. Background Art

[0002] Traditional ships use gasoline and diesel as fuel for ship power supply. The use of fossil fuels has caused certain pollution, including pollution to water and air. With the development of technology and the rise of new energy electric ships, the power of ships will gradually change from fossil fuel engines to power batteries. For example, an electric ship propulsion system and an electric ship with application number 201920269899.5 are disclosed. By adopting a yokeless segmented armature axial flux permanent magnet motor, the weight and volume of the propulsion system are reduced, the load and cargo space of the electric ship are increased, and the cargo efficiency of the electric ship is improved while the required motor power and torque remain unchanged. The electric ship realizes the use of power batteries for power supply.

[0003] Compared with traditional fossil energy ships, electric ships use power batteries for power supply. Due to the power requirements of ships, the power batteries have higher power and voltage, so generally multiple groups of batteries are arranged in series and parallel in the battery compartment. Due to the performance of the battery, the battery needs to be kept at a constant temperature. Traditional heat dissipation only considers heating and cooling the battery compartment through heating and cooling equipment. Although the constant temperature effect can be achieved, it consumes too much electricity and reduces the endurance. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a battery compartment constant temperature control system for a new energy ship and a new energy ship. During constant temperature control, heat is dissipated by ventilation to reduce the consumption of electric energy as much as possible while achieving cooling.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a battery compartment constant temperature control system for a new energy ship, comprising a heating and cooling device, a main control unit, and a temperature sensor arranged in the constant temperature compartment; the temperature sensor is used to collect temperature data of the battery in the battery compartment, and its output end is connected to the main control unit, and the output end of the main control unit is connected to the heating and cooling device, so as to control the cooling and heating working states of the heating and cooling device;

[0006] The control system also includes a ventilation system, which is connected to the main control unit and is used to achieve circulation between the air in the battery compartment and the air outside the ship according to the control signal of the main control unit.

[0007] The control system further includes an external humidity sensor, which is used to detect air humidity data outside the battery compartment, and an output end of the sensor is connected to the main control unit.

[0008] The control system also includes an in-compartment humidity sensor, which is used to collect the air humidity in the battery compartment. The output end of the in-compartment humidity sensor is connected to the main control unit. The output end of the main control unit is connected to a dehumidifier arranged in the battery compartment to control the operation of the dehumidifier.

[0011] The ventilation system includes a fan and a ventilation duct. The ventilation duct is used to connect the internal and external environments of the battery compartment. The fan is arranged in the ventilation duct to control the air flow. The control end of the fan is connected to the main control unit.

[0012] A valve for opening and closing the ventilation duct is provided in the ventilation duct, and the output end of the main control unit is connected to the valve for controlling the opening and closing of the valve.

[0014] The advantages of the present invention are as follows: when the battery compartment of a ship is temperature-controlled, heat is dissipated by ventilation when the temperature is high. This heat dissipation method meets the needs of ship navigation, because the ship will have a relatively high wind speed when it is driving, and the ambient wind and the battery compartment will interact to take away the heat, reduce the working time of the refrigeration equipment, and reduce the energy consumption of the electric ship, thereby improving the endurance to a certain extent; the humidity is detected, and the air humidity in the battery compartment is controlled and dehumidified to avoid excessive humidity in the ship's battery compartment; the humidity outside the battery compartment is detected, and when the humidity outside the battery compartment is too high, the ventilation system is prohibited or stopped. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is a brief description of the contents expressed in the drawings of the present invention and the symbols in the drawings:

[0016] Figure 1 It is a schematic diagram of the principle of the control system of the utility model. DETAILED DESCRIPTION

[0017] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0018] This application is mainly to achieve temperature control of the battery compartment of new energy electric ships. On the basis of existing refrigeration and heating equipment, a ventilation system is added to carry out heat interaction to avoid heat accumulation. At the same time, it can reduce the work of refrigeration equipment, reduce energy consumption, and indirectly improve the endurance of electric ships. The scheme is as follows:

[0019] like Figure 1 As shown, a battery compartment constant temperature control system for a new energy ship includes a heating and cooling device, a main control unit, and a temperature sensor arranged in the constant temperature compartment;

[0020] The temperature sensor is used to collect the temperature data of the battery in the battery compartment, and its output end is connected to the main control unit. The temperature sensor adopts a high-precision temperature sensor to detect the temperature data in the battery compartment with high precision;

[0021] The main control unit is the core controller, which is implemented using the STM32 series microprocessor. This series of processors has low cost, many IO port resources, simple and convenient development, and can realize functions such as data processing, transmission and control.

[0022] The heating and cooling equipment includes two parts, namely, a heating device and a cooling device, which can heat and cool the battery compartment respectively, thereby realizing temperature regulation in the battery compartment. For example, the heating and cooling equipment can be realized by using air conditioning equipment. The output end of the main control unit is connected to the heating and cooling equipment, which is used to control the cooling and heating working states of the heating and cooling equipment; the main control unit controls the heating and cooling equipment according to the collected temperature data in the battery compartment. In this embodiment, the constant temperature control system of the battery compartment also includes a ventilation system, which is connected to the main control unit. The ventilation system is used to realize the circulation between the air in the battery compartment and the air outside the ship according to the control signal of the main control unit. The ventilation system is used to realize the flow of air, thereby taking away the temperature in the battery compartment, avoiding heat accumulation, and reducing maintenance costs. Its working principle is: when the temperature sensor detects that the temperature in the battery compartment is higher than the set temperature threshold, it is judged that heat dissipation is needed at this time. The main control unit first controls the ventilation system to dissipate heat by ventilation. After the ventilation system works, it continuously monitors the temperature. If the temperature drops to meet the requirements, the ventilation system continues to work. If the battery compartment temperature still cannot be reduced to the set temperature after a certain period of time, the ventilation system is turned off, and the refrigeration equipment is turned on for refrigeration, thereby realizing the priority use of the ventilation system for heat dissipation during heat dissipation, saving energy. When the ventilation system cannot achieve the heat dissipation requirements or cannot dissipate heat to reduce the temperature to the set requirements, the refrigeration equipment is turned on, which can also save energy to a certain extent and avoid the purpose of directly turning on the refrigeration equipment to consume energy. Moreover, when the ship is sailing on the sea or river, there is no shelter and the wind will be relatively strong, so the ventilation system will better achieve heat dissipation. When turning on the ventilation system, it is also necessary to detect the temperature outside the warehouse. The ventilation system will only start when the temperature outside the warehouse is lower than the temperature inside the warehouse. Otherwise, it will not only fail to dissipate heat but may also increase the temperature inside the warehouse. Therefore, an outside warehouse temperature sensor is provided. The outside warehouse temperature sensor is connected to the main control unit. The temperature detected by the outside warehouse temperature sensor is sent to the main control unit. The main control unit compares the outside warehouse temperature with the inside warehouse temperature to determine whether to turn on the ventilation system.

[0023] In a preferred embodiment, the control system further includes an external humidity sensor, which is used to detect air humidity data outside the battery compartment, and its output end is connected to the main control unit. Due to the ship's driving environment, the humidity outside the compartment is sometimes relatively high. At this time, although the air with high humidity can also dissipate heat, it will affect the safety of the battery. Therefore, it is necessary to detect the air humidity outside the compartment, and the ventilation system is allowed to be turned on only when the air humidity meets the requirements, that is, the ventilation system is started to dissipate heat and cool down the temperature only when it is judged that the temperature inside and outside the compartment and the humidity outside the compartment meet the requirements.

[0024] Similarly, because humidity affects the battery, the present application provides an in-compartment humidity sensor in the battery compartment. The in-compartment humidity sensor is used to collect the air humidity in the battery compartment, and its output end is connected to the main control unit. The output end of the main control unit is connected to the dehumidifier provided in the battery compartment to control the operation of the dehumidifier. The in-compartment humidity sensor detects the air humidity in the compartment, and the main control unit controls the operation of the dehumidifier according to the in-compartment humidity data. When the air humidity is greater than the set value, the dehumidifier is started to dehumidify the air, otherwise the dehumidifier is turned off.

[0025] In another preferred embodiment, in order to monitor the constant temperature of the battery compartment, a cabin monitoring screen is provided, which is a large LED screen, arranged in the cabin monitoring room, and the main control unit is connected to the cabin monitoring screen, and the cabin monitoring screen is used to display the monitoring data in the battery compartment in real time. The main control unit drives and controls the monitoring screen to display data such as temperature, humidity, and working status of the ventilation system, so as to facilitate the ship monitoring operator to monitor the data.

[0026] When the temperature sensor in the warehouse detects a low temperature, heating is required. The heating is consistent with the traditional method, and the main control unit directly drives and controls the heating device to operate for heating.

[0027] In this embodiment, an alarm is provided in the monitoring room. The alarm is an audible and visual alarm. The main control unit is connected to the alarm. The alarm sends an alarm signal when the temperature is abnormal for a long time. The built-in timer of the main control unit or the external timing chip counts the temperature abnormality time. When the battery compartment temperature is greater than the set temperature or less than the set temperature and the duration is greater than the set time threshold, an alarm signal is sent through the alarm.

[0028] In a preferred embodiment of the present application, the ventilation system is mainly for ventilation and air flow inside and outside the warehouse. Therefore, when designing the ventilation system, the ventilation system of this embodiment includes a fan and a ventilation duct. The ventilation duct is used to connect the environment inside and outside the battery warehouse. The fan is arranged in the ventilation duct to control the air flow; the control end of the fan is connected to the main control unit. A valve for opening and closing the duct is arranged in the ventilation duct, and the output end of the main control unit is connected to the valve to control the opening and closing of the valve. Among them, the two ends of the office ventilation duct are connected to the warehouse and the other end is connected to the outside of the warehouse. The ventilation duct passes through the battery warehouse bulkhead. A fan is arranged in the duct to drive the air flow. At the same time, a valve is arranged inside the duct to realize the closing and opening of the duct, and realize the isolation and opening of the inside and outside of the warehouse. In order to realize the air flow and air pressure, at least two sets of ventilation ducts and corresponding fans can be arranged, so that one ventilation duct is exhausted from the outside to the inside, and the other is exhausted from the inside to the outside or does not have a fan, and is only composed of ventilation ducts and valves, so that the rapid circulation of gas can be realized.

[0029] The present application also provides a new energy ship, which includes the battery compartment constant temperature control system of the new energy ship in the above embodiment, thereby having the advantages of the constant temperature system in the above embodiment.

[0030] In this embodiment, the heating and cooling equipment uses efficient and energy-saving heating and cooling equipment, such as liquid cooling system or heat pipe technology, to provide stable heating and cooling effects while reducing energy consumption. A reasonable ventilation system is designed to ensure air circulation in the battery compartment to avoid heat accumulation and reduce maintenance costs. Considering the humid environment of the ship, a dehumidifier or heating equipment can be installed in the battery compartment to keep the battery at a constant temperature to extend the battery life.

[0031] The battery compartment is sensed, monitored and alarmed in real time, and the large screen in the cabin receives abnormal battery temperature in the first place and responds quickly.

[0032] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
