Embodiment 1

[0043] see figure 1 , is a lithium battery power supply control method, device and readable storage medium for marine ships. The lithium battery power supply system 100 includes: a lithium battery power supply device 110, a power consumption device 120 and a battery protection device 130. The lithium battery power supply system for marine ships 100 control methods include:

[0044] Step S100, when the lithium battery power supply device 110 supplies power to the power consumption device 120, the battery protection device 130 obtains the real-time voltage of the lithium battery power supply device 110;

[0045] Step S200, the battery protection device 130 determines whether the lithium battery power supply device 110 is low in power according to the real-time voltage;

[0046] In step S300, when it is determined that the power of the lithium battery power supply device 110 is insufficient, the battery protection device 130 controls the lithium battery power supply device 110 t...

Embodiment 2

[0051] In a specific example, see Figure 2-3 , the lithium battery power supply device 110 includes multiple strings of batteries; the battery protection device 130 obtains the real-time voltage of the lithium battery power supply device 110, specifically including:

[0052] Step S110, the battery protection device 130 obtains the real-time voltage of each string of cells in the multiple strings of cells;

[0053] The battery protection device 130 determines whether the lithium battery power supply device 110 has insufficient power according to the real-time voltage, specifically including:

[0054] In step S210 , the battery protection device 130 determines whether the lithium battery power supply device 110 has insufficient power according to the relationship between the real-time voltage of each string of cells in the multiple strings and the voltage threshold.

[0055] Furthermore, the lithium battery power supply device 110 contains multiple strings of battery cells, an...

Embodiment 3

[0057] In a specific example, see image 3 , the battery protection device 130 determines whether the lithium battery power supply device 110 is insufficient according to the relationship between the real-time voltage of each string of cells in the multiple strings of cells and the voltage threshold, specifically including:

[0058] Step S212, in the case that the real-time voltage of any at least one string of cells in the multiple strings of cells is lower than the voltage threshold, it is determined that the power of the lithium battery power supply device 110 is insufficient;

[0059] Step S211 , in the case that the real-time voltages of each string of cells in the plurality of strings are respectively greater than or equal to the voltage threshold, it is determined that the power of the lithium battery power supply device 110 is sufficient.

[0060] Further, the voltage threshold is the voltage range when the lithium battery power supply device 110 is normally powered. W...

Abstract

The invention provides a lithium battery power supply control method and device for ocean ships and a readable storage medium. A lithium battery power supply system comprises a lithium battery power supply device, a power consumption device and a battery protection device. The control method comprises the steps that under the condition that the lithium battery power supply device supplies power to the power consumption device, the battery protection device obtains the real-time voltage of the lithium battery power supply device; the battery protection device judges whether the power of the lithium battery power supply device is insufficient or not according to the real-time voltage; and under the condition that the power of the lithium battery power supply device is judged to be insufficient, the battery protection device controls the lithium battery power supply device to give an alarm for reminding. According to the invention, the technical problem that a lithium ion battery of an ocean ship cannot give a prompt indicating low power in the use process is solved, and after the voltage of the lithium ion battery is reduced to a certain degree, transient power failure is carried out to remind sailors that the power of the battery pack is low.

Description

technical field [0001] The present invention relates to the technical field of marine ships, in particular to a lithium battery power supply control method, device and readable storage medium for marine ships. Background technique [0002] As modern marine ships become more and more electrified and automated, they rely more and more on ship power stations and power systems, so the requirements for ships and power systems are also higher. More and more lithium-ion batteries are used in marine energy storage to replace the original lead-acid batteries. [0003] However, in the actual use of lithium-ion batteries, there is such a problem: compared with lead-acid batteries, the output power of lithium-ion batteries will not decrease with the reduction of power. Therefore, when the lighting system using lead-acid batteries is insufficient, due to the reduction of output power, the lighting level will gradually weaken, thereby playing a role in reminding the crew; while lithium-i...
