A power control circuit for a vehicle includes a power switch, N-type semiconductor switches electrically connected between a power supply terminal to which an input voltage is applied and the power switch and in which the N-type semiconductor switches are connected back-to-back, a charge pump circuit for generating a drive voltage to drive the N-type semiconductor switches by boosting the input voltage, a reverse voltage protection circuit electrically connected between an output terminal of the charge pump circuit and a node in which the N-type semiconductor switches are connected to each other, a microcontroller for generating a pulse width modulation signal for the operation of the charge pump circuit, and a voltage attenuation circuit for attenuating the drive voltage and applying the attenuated drive voltage to the microcontroller.

Power control circuit for vehicle and operating method thereof

An apparatus for protecting a battery pack is configured to release reverse connection of the battery pack by detecting the reverse connection of the battery pack even in a case where the reverse connection of the battery pack is not detected through a battery pack controller.

Apparatus for protecting battery pack

The present invention relates to a system for predicting battery usage habits and battery discharge tendencies. The system includes a battery sensor that senses a state of charge (SOC) of a battery and a controller hat calculates battery power generation amount during driving time of a vehicle and battery consumption during parking time of the vehicle based on information sensed by the battery sensor. A storage unit for stores the battery power generation amount, the battery consumption, time at which the vehicle is tuned on/off, and time at which the controller enters a sleep/wake-up state.

System for predicting battery usage habits and battery discharge tendencies

An apparatus for managing power of a vehicle includes a processor that controls a bypass path for bypassing an input power or a boosting path for boosting the input power corresponding to an idle mode signal, a booster that boosts the input power corresponding to a driving signal to generate an output power, a control circuit that selectively supplies a power for operating the booster corresponding to an output signal of the processor in a boost mode, and a pulse width control circuit that controls a duty of the driving signal corresponding to an output signal of the control circuit.

Apparatus for managing power of vehicle and method of controlling the same

There are provided a system and a method for controlling power of a high speed vehicle. The system for controlling power of a vehicle includes: a latch relay configured to supply power to a vehicle load or to block power to the vehicle; a communication part configured to output a driving signal when a wakeup signal is received; a pulse generator configured to output a one shot pulse that turns on the latch relay when the driving signal is applied; and a processor configured to control a driving of the latch relay turned on by the one shot pulse when being initialized.
