Description

Technical Field

[0002] With the development of society, oceans and lakes occupy a very important position in human social development. With the rapid development of shipping and tourism, environmental and energy problems have become common problems worldwide. This is because fuel-powered ships used to cause a lot of pollution when sailing on water, resulting in serious water pollution problems, threatening the lives of many aquatic organisms and disrupting the ecological balance.

[0003] With the continuous development of new energy technologies, electric boats have emerged, effectively addressing environmental pollution issues. As a type of electric vehicle, they are propelled by electricity generated from batteries or marine generators. Solar-powered electric boats, in particular, use solar panels to directly convert sunlight into electricity, replacing fuel-powered propulsion, reducing environmental impact and energy consumption. Since electric boats are powered by electricity, they require battery systems to propel them. The need for movement places voltage requirements on the battery system, and the presence of human activity on board, which also requires electricity, places demands on the battery system's capacity.

[0019] The technical solution provided by this utility model has the following advantages:

[0020] 1. The battery system provided by this utility model includes a bracket, a transfer component, and an energy component. The bracket is suitable for installation on an electric boat. The transfer component is installed on the bracket. The energy component includes a plurality of energy components and a plurality of first connectors. All energy components are spaced apart on the bracket. At least one first connector is connected between any two adjacent energy components.

[0021] This battery system, through a relay component and energy components mounted on a support frame, allows the support frame to be installed on the electric boat under external force, thus synchronously installing the relay component and energy components on the electric boat. Furthermore, mounting the relay component and all energy components on the electric boat via the support frame reduces the space occupied by the electric boat. The energy components specifically include several energy elements and several first connecting components, with the relay component and all energy elements spaced apart on the support frame. Each pair of adjacent energy elements is connected by a first connecting component, and the relay component is connected to each of the two energy elements at its end by a first connecting component. In this way, the relay component and all energy elements are connected in series and electrically together through all the first connecting components, thereby ensuring that all energy elements have the required voltage. Combined with the battery capacity, the voltage and capacity of the battery system can meet the needs of the electric boat. In addition, when the electric boat has greater requirements for the battery system capacity, multiple battery systems provided in this embodiment can be installed on the electric boat. By connecting all the battery systems in parallel, the capacity of all the battery systems can be superimposed. In this way, the superimposed capacity of all the battery systems can meet the further capacity requirements of the electric boat. Of course, for different electric boats, since the voltage and capacity requirements of electric boats are different, we can also adjust the number of energy components in a single battery system or the number of battery systems on the electric boat so that the voltage and capacity of the battery system can meet the needs of different models of electric boats.

[0022] 2. The battery system provided by this utility model includes a first interface and a second interface on any energy component. The two ends of a first connector are respectively connected to the second interface on one energy component and the first interface on another energy component. A transfer component is provided with a third interface and a fourth interface. The third interface is adapted to connect to the first interface on an end energy component via the first connector, and the fourth interface is adapted to connect to the second interface on another end energy component via the first connector. The transfer component is provided with at least two fifth interfaces, any one of which is adapted to connect to an electric boat via the first connector to provide power to the electric boat.

[0023] This battery system, through a first and second interface on the energy components (both in this embodiment being power connection interfaces), allows for electrical connection between adjacent energy components. The first connector connects to the second interface on one energy component and the first interface on the other, respectively. Similarly, a third and fourth interface on the relay component (both in this embodiment being power connection interfaces) allows for electrical connection between the relay component and the two energy components at the end. The third interface on the relay component connects to the first interface on one of the end energy components via the first connector, and the fourth interface connects to the second interface on the other end energy component via the first connector. This also connects the relay component to the two end energy components in series with all energy components.

[0025] This battery system, through a sixth interface on the relay unit, a seventh interface on the energy unit, and a second connector between the relay unit and all the energy units, achieves communication interface connection between the relay unit and all the energy units. In this embodiment, the sixth and seventh interfaces are communication interfaces, and the second connector is a second cable. One end of the second connector is connected to the sixth interface on the relay unit, and the other end is connected to the seventh interface on each of the energy units in sequence. In this way, the relay unit can receive the operating data of all the energy units through the second connector and monitor all the energy units through this operating data. The system includes several eighth interfaces on the relay component, two ninth interfaces on the energy components, and a third connector within the battery system. In this embodiment, the eighth and ninth interfaces are heating interfaces, and the third connector is a third cable. Part of the third connector connects to the ninth interfaces on two adjacent energy components at both ends, while the other part connects to the eighth interfaces on the relay component and the ninth interfaces on the two energy components at the ends. This connects the heating interfaces between the relay component and all energy components, allowing the relay component to heat all energy components and increase their temperature, thereby improving the power output efficiency of all energy components. Two tenth interfaces on the relay component, which are power receiving interfaces in this embodiment, connect to the electric boat via the first connector, enabling the relay component to receive power from the electric boat and thus operate normally.

The transfer component 2 is connected to each of the two energy components 31 at its end by a first connecting member. Thus, the transfer component 2 and all the energy components 31 are connected in series and electrically together through all the first connecting members. By combining the voltage and capacity of all the energy components 31, the voltage and capacity of the battery system can meet the needs of the electric boat. In addition, when the electric boat has greater requirements for the capacity of the battery system, multiple battery systems provided in this embodiment can be installed on the electric boat.
