Abstract: An electric source noise pattern analysis method for vehicle battery protection and power management and device thereof provides ignition status recognized against battery discharge due to electric equipment requirement. This device is connected in parallel with the main battery and backup battery of a vehicle. This device features the addition of a source characteristic sensing unit which analyzes voltages, currents, power noises of main battery and backup battery, a pattern analysis method which utilizes the sensing characteristics to recognize the running and power used situation of vehicle, and a power management and control unit which employs at least one adjustment timer to manage main battery and backup battery relied on the vehicle situation. The device which operates to connect and disconnect the main and the backup battery from the load based on a sophisticated management algorithm to control to prevent from power exhausted by electric appliances.

Abstract: A battery charger with electroluminescent panel primary comprises a battery charger, an electroluminescent panel and a housing. The electroluminescent panel is connected to a battery charger and having a driving controller and cables of driver circuit, the battery charger having a charger controller and cables of charger circuit, and the housing accommodating the battery charger and electroluminescent panel. The electroluminescent panel is attached to the battery charger by means of the connecting cables to be displayed the information of charging. The electroluminescent panel is installed at easy-to-reach display location for the convenience of its users. Other features beneficial to users include a better display interface of charged progress, charging capacity display, alarm information, company logo, as well as, indicating the battery capacity instead of voltage instrument when the city power source does not connect with the battery charger.

Abstract: An electric source noise pattern analysis method for vehicle battery protection and power management and device thereof provides ignition status recognized against battery discharge due to electric equipment requirement. Such battery discharge includes normal use of electric appliances and inadvertent use of electric devices. This invention is connected in parallel with the main battery and backup battery of a vehicle. Featuring the addition of a source characteristic sensing unit which analyzes voltages, currents, power noises of main battery and backup battery, and a pattern analysis method which utilizes the sensing characteristics to recognize the running and power used situation of vehicle, and a power management and control unit which employs at least one adjustment timer to manage main battery and backup battery relied on the vehicle situation.

Abstract: Methods and device for battery charging and diagnosis provide a measuring batter energy state in which charging strategy alternate with the minimize balance between battery energy state and charging energy in which the balance is existed in battery energy barrier. Variance battery energy barrier derives adaptive charging cycle and charging protection in to approach the requirements of safety, full charge and high performance for lead-acid battery.
