Application of LTC6803 in battery 18650 genuine energy storage management system
At present, research on battery management systems at home and abroad is more concentrated in the field of electric vehicles. Energy storage battery management systems are a key part of battery energy storage power stations. Most battery companies in my country have just started to develop technology in this area. A lithium-ion battery management system suitable for large-capacity energy storage technology is proposed in the literature, and a systematic analysis is conducted from the structure, function and management perspective of the hierarchical management system. Other major countries (such as the United States, Europe and other developed countries) have carried out research and development in the key technology field of energy storage, and related technology research and development and demonstration activities are progressing rapidly.
From the perspective of environmental protection and economy, this work selected some batteries from the retired electric bus nickel-metal hydride power battery system as the energy storage battery, and designed an energy storage battery management system. The LTC6803 collects the voltage and temperature information of the entire energy storage system and controls the battery pack balancing function.
1. Energy storage system architecture
The battery management side architecture of the energy storage system designed in this work is shown in Figure 1, which can be functionally divided into three basic units: acquisition, control and processing, and peripherals. The microcontroller system uses Freescale 16-bit MC9S12XEG128 as the microcontroller. The acquisition unit includes battery pack voltage sampling and temperature sampling; the current control unit includes battery pack balance control and relay control; the processing and peripheral unit is mainly responsible for microcontroller signal processing and communication peripherals. and other control modules.
LTC6803 is widely used in electric vehicles, energy storage and other fields because of its advantages such as high sampling accuracy and simple wiring. Therefore, the power management dedicated chip LTC6803 is selected as the battery pack power, H≤ and temperature sampling front end. It integrates 12 voltage sampling channels It has 2 channels of temperature sampling and a controllable battery balancing switch to balance the battery when necessary to maintain battery consistency.
2. Hardware circuit design of power management chip LTC6803
2.1. Basic schematic diagram and introduction of LTC6803
In this design, C0 in Figure 2 is connected to the negative terminal of the battery pack, C1~C12 are voltage acquisition ports, S1~S12 are balancing switches; GpIO. and VTEMp. The pins are connected to the temperature acquisition module. It should be noted that the power supply of LTC6803 is completely provided by the battery pack, and there is no need to configure the power supply circuit on the control board. If it is connected to an isolated power supply, the LTC6803 can be turned off simply by disconnecting pin V.
2.2. Communication design
LTC6803 has an SpI bus-compatible serial port, and the microcontroller can exchange data with it through this bus. The microcontroller can collect the voltage and temperature information of the battery pack and control the battery balancing circuit in real time by configuring the corresponding internal registers of the LTC6803. In Figure 1, the SpI signal isolation circuit uses the isolation chip ADuM3150 with 4 high-speed channels to ensure stable transmission of the SpI signal.
