Abstract: Text data transmitted by a user device to a first server is retrieved. The text data is processed to determine whether an information recommendation rule set includes an information recommendation rule matching the text data. The information recommendation rule is set based on a recommendation information. If the information recommendation rule set includes the information recommendation rule matching the text data, the recommendation information is retrieved from a second server. A recommendation based on the recommendation information is transmitted to the user device.

Abstract: A hybrid battery-charging device with input terminals for connecting a current source, first and second battery connections for connecting a lead-acid battery and a high-cycle chemical battery. A two-way DC/DC converter with first and second sets of terminals is connected with the second and first battery connections. A charge and discharge control system includes a controller unit, a control output for controlling the two-way DC/DC converter, and sensing inputs for sensing a charge state, an internal resistance of the lead-acid-battery and state of charge of the high-cycle chemical battery. The charge and discharge control system controls the two-way DC/DC converter such that the lead-acid battery is charged if its charge start is below a pre-determined threshold and that the high-cycle chemical battery is charged if its charge state is below a pre-determined threshold and if the state of charge of the lead-acid battery is above a pre-determined threshold.

Abstract: A battery charging apparatus. The apparatus includes two or more hybrid battery charging devices. Each hybrid battery charging device includes input terminals for connecting a photovoltaic panel, first battery connections for connecting a lead-acid battery, second battery connections for connecting a high-cycle chemical battery, a two-way DC/DC converter, a charge and discharge control system, which is connected to the two-way DC/DC converter, and output terminals for connecting a load.

Abstract: A hybrid battery-charging device with input terminals for connecting a current source, first battery connections for connecting a lead-acid battery and second battery connections for connecting a high-cycle chemical battery. A two-way DC/DC converter with first and second sets of terminals is connected with the second battery connections, and with the first battery connections. A charge and discharge control system of the charging device is operative to detect when an internal resistance of the lead-acid battery exceeds a predetermined resistance threshold, and to control the DC/DC converter, in response to the internal resistance of the lead-acid battery exceeding the predetermined resistance threshold, such that, in a discharge mode, the lead-acid battery and the high-cycle chemical battery are discharged in parallel during a parallel discharge phase.
