Battery Management System and Charging Training Platform

Product Overview:
This product utilizes a mainstream new energy lithium iron phosphate (LFP) battery pack. Each cell is 3.2V 20AH, with a square aluminum casing, arranged in 24 strings for a total capacity of 73.6V 50AH. It features an integrated BMS (Battery Management System) with a CAN bus and passive balancing capabilities.

This product realistically demonstrates the connection and control relationships, installation locations, and operating parameters of the core components of a lithium iron phosphate battery pack, as well as high-voltage system safety precautions. It also cultivates trainees' ability to analyze and handle faults in lithium iron phosphate battery packs (BMS).

Features:
1. A realistic and operable new energy power battery charging and discharging assembly, fully demonstrating the structural composition and logical control relationships of each major component. All major components are mounted on a training platform with electrical connections identical to those in a real vehicle, allowing for easy disassembly and reassembly. This enables trainees to master the key points of high-voltage system component disassembly and reassembly, as well as safety protection measures, during the connection and reassembly process.

2. The BMS (Battery Management System) features passive balancing and switch control protection (cell disconnection, short circuit, overvoltage, undervoltage, overcurrent, and overtemperature). It communicates with the on-board charger via CAN bus, controlling the charger's operation and estimating SOC (State of Charge).

3. It acquires cell voltage, total voltage, current, and temperature data. It has comprehensive fault alarm functions, including voltage, current, and temperature fault alarms.

4. It features SOC estimation, charge/discharge control, and passive balancing management. The system switches use passive mechanical contacts.

5. A 7-inch touchscreen display is mounted on the panel, allowing observation of various parameters during the charge/discharge process, and understanding of the control logic and parameter changes of key components. It comes with compatible BMS host computer calibration software.

6. The training platform is equipped with a discharge module to simulate the energy consumption process of a vehicle. The discharge current can be selected. The power battery pack is equipped with a mechanical maintenance switch for new energy vehicles.
