The analog control system includes a pulse width modulation (PWM) output unit that is configured to output a PWM signal to the converter and an integrated control unit that is configured to sense an input voltage and an output voltage of the converter. The analog control system may be implemented on a printed circuit board having a first ground voltage stage connected to the PWM output unit, a second ground voltage stage separated from the first ground voltage stage by a first predetermined interval and connected to the integrated control unit. A filtering unit is disposed between the first ground voltage stage and the second ground voltage stage to pass an output signal of a predetermined band from the PWM unit to the integrated control unit.

摘要： A power relay assembly (PRA) and a method of controlling the same are provided. The power relay assembly includes a first main relay for interconnecting negative voltages of a battery and an inverter, a second main relay for interconnecting positive voltages of the battery and the inverter, and a pre-charge relay connected in parallel to the second main relay. A controller executes the open or short sequence of the first main relay, the second main relay, and the pre-charge relay based on the opening and closing operation between the battery and the inverter or the charging and discharging operation of the battery. The opening and closing operation is divided into an opening operation and a closing operation between the battery and the inverter, and the charging and discharging operation is divided into a charging operation and a discharging operation of the battery.

摘要： A vehicle battery system and a method of controlling charge of a battery in the system are provided. The system includes a first battery module that has a plurality of battery cells connected to each other in series and a second battery module that has a plurality of battery cells connected to each other in series. The second battery module is connected to the first battery module in series. A controller then monitors a state of charge of each of the first and second battery modules, such that when the state of charge of one of the first and second battery modules is less than a predetermined level, the controller performs active cell balancing between the battery cells of the first battery module and the battery cells of the second battery module.
