الوصف

EK-YT**1 system is mainly used in light vehicles, mini vehicles, track bikes, electric motorcycles and other small electric vehicles field. The system integrates the function of data collection, stem analysis and control in EK-YT-M***4 module. Data storage module and touch screen module can be added to the system; The system has a high-precision voltage detection, current detection, temperature detection, SOC estimation algorithm, lossy balance, CAN BUS communication, RS**5 communication, relay control, switch signal output and more functions. Product Features: The system adopts highly integrated automotive-level control chip which is compact size but with powerful functions; The system realizes collection, testing, communication and control functions with only four interfaces, which greatly reduces the complexity of the inter-connection; The system has high accuracy in voltage, current and temperature data collection; The system adopts a double isolation design; Each functional port is with protection, with high-security; The system goes through EMC, high and low temperature, vibration, salt spray and other environmental testing, with strong reliability; Efficient balance, one-way lossy balance maximum current can reach **0mA, and balance fail-safe function is designed to protect the battery; Real-time display of system information via the LCD screen or PC; Support 2 ~ 8G high-capacity data storage; The system has strong electrical control interface isolation design, which can improve effective immunity.
