Pure electric ship power battery automatic monitoring system and method

Abstract

The invention provides a pure electric ship power battery automatic monitoring system which comprises a remote monitoring platform, a ship-mounted terminal, a BMS and a power battery pack. The remotemonitoring platform is in wireless connection and communication with the ship-mounted terminal. The ship-mounted terminal is in connection and communication with the BMS through a CAN bus. The BMS isused for monitoring the state information of the power battery pack and sending the state information to the ship-mounted terminal. The ship-mounted terminal is used for awakening the BMS to run and sending the state information to the remote monitoring platform. The remote monitoring platform is used for processing the state information and judging whether abnormity exists or not. The remote monitoring platform is further used for remotely setting the dormancy time of the ship-mounted terminal and the running time of the BMS after the ship-mounted terminal is started. The invention further provides a pure electric ship power battery automatic monitoring method. According to the method, when a pure electric ship is shut down and settled, the BMS is awakened by the ship-mounted terminal tostart running, information monitoring is conducted on the power battery pack and the monitoring information is uploaded to the remote monitoring platform to be processed, therefore, potential safety dangers are timely eliminated, and the cost is low.

Description

【Technical field】 [0001] The invention belongs to the technical field of battery monitoring, and in particular relates to an automatic monitoring system and method for a pure electric ship power battery. 【Background technique】 [0002] At present, pure electric ships usually dynamically monitor the state changes of the power batteries of their energy storage systems through the BMS (Battery Management System) to ensure that the power battery systems are in normal use. In the prior art, the pure electric ship only monitors the state of the power battery when it is running or charging, and forwards the state information of the power battery to the remote monitoring platform through the shipboard terminal. After the investigation and data analysis, when the power battery of the pure electric ship is turned off and placed, the power battery loses power, a single unit fails, or a short circuit catches fire, etc., due to the lack of information on the power battery when the fire i...

Problems solved by technology

After the investigation and data analysis, when the power battery of the pure electric ship is turned off and placed, the power battery loses power, a single unit fails, or a short circuit catches fire, etc., due to the lack of information on the power battery when the fire is turned off in the big data of the remote monitoring platform, it is impossible to detect or take measures in time It will often cause serious safety accidents or serious damage to the power battery.
