Description

Technical Field

[0002] Battery energy storage system is an important part of electric vehicle new energy power, smart grid and energy Internet. In particular, electrochemical battery energy storage system is a battery string composed of multiple battery cells connected to enter the inverter equipment for charging and discharging, and completes power regulation and charging and discharging in a controlled manner. Due to the differences in the physical and chemical properties of each battery cell, coupled with the differences in environmental dimensions during installation and operation, the batteries in the battery string produce inconsistencies in voltage and power, which affects the overall efficiency and utilization of the battery string and also brings safety hazards.

[0003] In this regard, real-time monitoring of the consistency of power parameters such as voltage and power of each battery cell or battery pack in a battery string and control to prevent overcharging, over-discharging, and excessive temperature rise are the key to the safe, healthy, and efficient operation of the energy storage system. Most of the existing technologies directly connect multiple battery cells in series or in parallel to form a battery pack, and then connect multiple battery packs in series to form a battery string unit module. Most battery management systems (BMS) use signal acquisition sensors connected to each battery cell and battery pack through a wiring harness to monitor the voltage, current, and temperature of the battery cell and battery pack in real time. Each battery cell and battery pack needs to be configured with at least three wires, which not only greatly increases the installation difficulty and accuracy of the monitoring and management system, but also the huge number of wiring harnesses distributed in the battery string module poses an immeasurable risk to the energy storage system.
