Embodiment Construction

[0021] Example of battery pack monitoring system

[0022] This embodiment provides a battery pack monitoring system, which includes two major parts, namely the battery pack and the monitoring unit, wherein the monitoring unit implements the monitoring of the battery pack, such as a BMS. Since the monitoring unit belongs to conventional equipment, this embodiment does not monitor The structural composition of the unit is described in detail. The battery pack includes at least two single battery units, and the specific number is set according to actual needs, for example, the number of single battery units is specifically set according to the power of the electrical equipment.

[0023] For any single battery unit, including a single battery body and an information collection unit, wherein the single battery body is an energy storage and energy supply part, and the information collection unit is used to collect relevant data information of the corresponding single battery body, a...

Abstract

The invention relates to a storage battery pack monitoring system, a storage battery pack and a single battery unit thereof. The storage battery pack monitoring system comprises a storage battery packand a monitoring unit; the storage battery pack comprises at least two single battery units; each single battery unit comprises a single battery body and an information collection unit integrated with the corresponding single battery body; the information collection unit is used for collecting related data information of the corresponding single battery body; the information collection units in the respective single battery units are all connected to a collection bus; and the monitoring unit is connected with the collection bus through a communication line so as to be in communication with each information collection unit. Therefore, the data collection circuits between the storage battery pack and the monitoring unit are greatly reduced, and a condition that each single battery unit outputs the collection circuit is not needed; the problem of influence to wring attractive appearance caused by relatively more connecting lines between the storage battery pack and the monitoring unit can be solved; and in addition, the problem of insufficient electrode post height cased by more electrode post collection lines can be avoided.

Description

technical field [0001] The invention relates to a battery pack monitoring system, a battery pack and a single battery unit thereof. Background technique [0002] At present, the valve-regulated lead-acid battery pack can provide reliable control power for relay protection, self-safety devices and accident lighting, etc., and provide reliable operating power for circuit breakers in the case of station AC power loss. Therefore, Valve-regulated lead-acid batteries play a pivotal role in substations. At the same time, valve-regulated lead-acid batteries are called "maintenance-free batteries". Charging voltage, current, etc., cannot accurately measure the real capacity of the battery pack and predict the usable time of the battery pack, which makes the operation of the valve-regulated sealed lead-acid battery pack have many potential safety hazards, seriously affecting the safe operation of the DC system . If the outdated single batteries that have problems cannot be found an...
