摘要： A communication circuit facilitating communication between a first equipment and a second equipment including a conversion circuit, an input port, an output port, and a communication port is disclosed. The conversion circuit converts an input signal to a first intermediate signal, and converts a second intermediate signal to an output signal. The input port inputs the input signal to the first conversion circuit. The output port outputs the output signal to the control unit. The communication port inputs the second intermediate signal to the conversion circuit, and outputs the first intermediate signal to the second equipment. A voltage of the first intermediate signal is determined based on a voltage of a power source if the first intermediate signal is logic high, and a voltage of the second intermediate signal is determined based on the voltage of the power source if the second intermediate signal is logic high.

摘要： A battery management system includes a switch array, a first controller and a second controller. The switch array selects a battery module from multiple battery modules in a battery pack based upon a conduction state of the switch array. The first controller is coupled to the switch array and receives measurement information of cells in the battery pack through the switch array. The second controller is coupled to the switch array and the first controller and provides a control signal to control the conduction state of the switch array. The first controller further controls a balance circuit coupled to the battery pack to balance a selected battery module if the selected battery module is identified as an unbalanced battery module based upon measurement information associated with the selected battery module.

摘要： A system and methods for controlling an electric motor in an electric vehicle. The system includes a battery management system and a motor controller. The battery management system monitors output voltage of each individual cell unit in a battery pack with a plurality of cell units and generates a state signal and a count value according to the monitored output voltages. The motor controller receives the state signal and the count value from the battery management system and controls the output current to the electrical motor. The battery management system generates the state signal in a first state if none of the monitored output voltages is below a predefined voltage for longer than a predefined period. The battery management system increases the count value each time a monitored output voltage drops below the predefined voltage. The cell units in the battery pack are protected by the battery management system.
