Embodiment Construction

[0015] like figure 1 The overall structure diagram of the ship battery management system is shown, including ship AC power grid 1, isolation transformer 2, circuit breaker 3, converter 4, battery cluster 5, strong current control module 6, total battery management system BMS7, local display 8, monitoring Alarm system 9, electric propulsion load 10.

[0016] A ship battery management system that can realize the following three energy flow processes. a. The ship's AC power grid 1 isolated by the isolation transformer 2 directly supplies power to the electric propulsion load 10 . b. After the ship's AC power grid 1 is isolated by the isolation transformer 2 , it passes through the closed circuit breaker 3 and then the converter 4 to convert the AC power into DC power to charge each battery cluster 5 . c. The electric energy of each battery cluster 5 is converted into alternating current by the converter 4 and then supplies power to the electric propulsion load 10 through the ci...

Abstract

The invention relates to a ship battery management system. The ship battery management system comprises a plurality of battery clusters in parallel, wherein each battery cluster comprises a cluster battery management system CBMS and a plurality of series battery packs, each battery pack comprises a pack battery management BBMS and a battery box, the battery box is formed by connecting a pluralityof single batteries in series and then connecting the plurality of single batteries in parallel, the battery management system comprises a third battery management system, the pack battery managementsystem BBMS is used for directly managing the single batteries in the battery box in pack, the cluster battery management system CBMS is arranged between the pack battery management system BBMS and atotal battery management system BMS and is used for managing each series battery pack in the cluster, the total battery management system BMS is used for managing the integral state and the charge-discharge process of the batteries under matching of a strong power module, and each stage of battery management system communicates via a CAN bus. With the adoption of a multi-stage management method, the ship battery management system is flexible and convenient; and in the battery management system, the management demands of different ship battery power systems can be satisfied by configuring parameters.

Description

technical field [0001] The invention relates to a battery technology, in particular to a ship battery management system. Background technique [0002] With the development of new energy technology and the improvement of people's requirements for ship performance, pure electric ships and hybrid ships have been used more and more in recent years. However, the current battery management systems of pure electric ships and hybrid ships basically use conventional vehicle battery management systems. [0003] Since the working environment of ships is different from land-use products, the control and safety protection requirements for marine battery power systems are very different from those of vehicle battery management systems; ships do not have the characteristics of mass production of cars, and the power of different ship designs The voltage level, capacity, cooling method, layout type and heat dissipation conditions of the battery are different. The cost of custom-designing l...
