Abstract: In an existing permissible current computation algorithm, an excessive current is caused to flow by controlling the battery having a steep change region in the battery characteristic. On the other hand, when the current is reduced and the output is suppressed, the battery performance cannot be sufficiently utilized. Moreover, with countermeasures to increase the number of data points, the amount of data increases and thus can not be installed in the microcomputer. A battery control device that computes a permissible current of a battery having a battery characteristic non-steep change region having a small battery characteristic change and a battery characteristic steep change region having a battery characteristic change greater than in the battery characteristic non-steep change region, in which in a case where the battery enters the battery characteristic steep change region after a predetermined time from a present state, a battery characteristic value is calculated by using an absolute value of a slope greater than an absolute value of a slope in the present battery characteristic.

Abstract: A portable green power device includes a case, an energy storage module, a kinetic power generating module, a control unit, and a port for discharging. The energy storage module has an input terminal set, an output terminal set, a protection circuit, and a parallel dynamic self-balancing mechanism. The output terminal set may be connected to an additional energy storage unit to expand power storage capacity of the portable green power device. The parallel dynamic self-balancing mechanism enables synchronous charging and discharging under a voltage level which is dynamically reached and falls between voltages of all the energy storage units connected in parallel. The control unit tracks and collects energy generated by the kinetic power generating module at a maximum power point and allows transfer of the generated energy to the energy storage module.

Abstract: The present disclosure discloses a voice remote controller and a power supplying method thereof. The voice remote controller comprises: a noise gathering module for gathering ambient noise at the periphery of the voice remote controller by using a sound aperture array; a sound-electricity converting module for converting the ambient noise gathered by the noise gathering module into an electrical signal; and an energy storing module for storing the electrical signal converted by the sound-electricity converting module as electric energy and supplying power to the voice remote controller. According to the present disclosure, ambient noise is gathered by a sound aperture array and converted into electricity used as the working energy, thereby avoiding battery replacing or frequent charging. When a voice function of a voice remote controller is turned off, all of the gathered ambient noise is converted into electricity, thereby improving the energy utilization rate. By adjusting the number of opened sound apertures in the sound aperture array and changing the noise gathering angle, ambient noise can be separated from a voice signal of the user, and by inverting a noise waveform and superimposing the same onto the voice signal, ambient noise in the voice signal can be filtered out, thereby reducing the negative effects of ambient noise on the voice remote controller.
