Problems solved by technology
The marine battery system is different from the vehicle battery system. The battery capacity is large, and multiple sets of batteries are often connected in series and parallel. For example, charging multiple sets with one charging gun like the vehicle charging method takes too long and cannot meet the requirements. A charging gun can charge multiple sets of batteries at the same time, which often cannot meet the operational needs

Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0017] like figure 1 Shown is a schematic diagram of the structure of the shipboard interface and protocol conversion device for lithium battery ship DC charging, including: a control device, a monitoring device, and a DC charging socket box. Among them, the DC charging socket box selects the required specification and quantity of charging guns according to the battery system power of the ship, the DC bus voltage level and the ship's demand for charging power, and completes the mechanism design, electrical principle design, and internal copper bar design of the charging socket...

The invention relates to a lithium battery ship direct-current charging shipborne interface and protocol conversion device which comprises a control device and a direct-current charging socket box, a vehicle standard socket on the direct-current charging socket box is connected with a direct-current shore power device, and the direct-current charging socket box converges currents of a plurality of accessed charging guns. The control device is in protocol communication with the direct-current shore power device through a charging communication interface of the direct-current charging socket box, the control device is simultaneously connected with a local management unit BMS of the lithium battery ship battery pack, and the control device outputs a control signal to control shore power converged by the direct-current charging socket box to charge the ship battery pack. The vehicle direct current charging device with mature technology on the market is suitable for the ship field, the period and the cost for developing a ship special charging device are saved, and the vehicle direct current charging device is suitable for rapidly developing ship charging requirements.
Description
technical field [0001] The invention relates to a power supply control technology, in particular to an onboard interface and a protocol conversion device for direct current charging of a lithium battery ship. Background technique [0002] In recent years, environmental protection has gradually become the focus of attention, and green environmental protection, energy conservation and emission reduction have become the consensus of most countries around the world. In such a big environment, with the development of the global shipping industry, the pollution caused by ships is also attracting more and more attention of the international community. At present, new energy propulsion has become an important development direction of the power system of small and medium-sized ships in inland rivers, and the transformation of new energy drive is an inevitable trend in the future. The marine power battery system is currently on the eve of an impending market explosion. For pure batt...
