The rapid growth of infotainment has resulted in higher costs for automobile manufactures as multiple USB chargers are now designed into each model. Molex offers an off-the-shelf USB charger that is standard for many transportation vehicle applications. This single charger eliminates tooling and engineering support and reduces overall costs. Molex also designs custom in-vehicle smart chargers that follow a device’s profile to provide the maximum power allowed by the device manufacturer, ensuring fast and effective charging.
To protect from improper charging, smart phones and tablets are designed to allow a minimum current when plugged into in-vehicle USB ports that aren’t smart chargers. As a result, a device uses more power than it receives when a driver charges it while playing music or getting directions. Possible shorts and overcurrent conditions created by electrical events in automobiles can damage devices that are plugged into in-vehicle chargers. Molex Custom In-Vehicle Smart Charging Modules have protective circuitry built in to protect devices from shorts and overcurrent conditions.
