Remote controlled device and method for battery charging and maintenance

A device for battery charging and maintenance, comprising:

• a terminal for an accumulator battery;
• the terminal having a positive side connected to a current sensor;
• the terminal having a negative side connected to a ground;
• the current sensor is electronically connected to a rectifier, said rectifier comprising at least three rectifier thyristors, and an inverter, said inverter comprising at least three inverter thyristors;
• the rectifier and the inverter are connected to a transformer;
• the transformer is connected to a power supply;
• and
• the terminal, the accumulator battery, the inverter, the rectifier, and the current sensor, together, forming a power supply network, said power supply network being electronically connected to a phase-pulse control system,
• said phase-pulse control system being configured to cause the power supply network to perform at least one stage, said stage comprising:
• forming a first pulse, said first pulse being formed by the rectifier, said first pulse being synchronized via a front transition of a sinusoidal inter-phase voltage signal, wherein a first timer-counter controlling a first set of rectifier thyristors is synchronized by a first inter-phase voltage, wherein a second timer-counter controlling a second set of rectifier thyristors is synchronized by a second inter-phase voltage, wherein a third timer-counter controlling a third set of rectifier thyristors is synchronized by a third inter-phase voltage,
• measuring a total period (T) in the power supply network, said measuring being performed by one of said timer-counters,
• causing a pause, said pause being caused by an end of an interval prior to a consecutive front transition, said pause further causing a closure of all rectifier thyristors,
• forming a second pulse, said second pulse being formed by the inverter, said second pulse being synchronized at moments of inter-phase voltage peaks in the power supply network, said inter-phase voltage peaks being determined by adding an interval of T/4 to a given moment of a front transition of an inter-phase voltage, wherein a fourth timer-counter controlling a first set of inverter thyristors is synchronized by the first inter-phase voltage, wherein a fifth timer-counter controlling a second set of inverter thyristors is synchronized by the second inter-phase voltage, wherein a sixth timer-counter controlling a third set of inverter thyristors is synchronized by the third inter-phase voltage;
• and
• repeating said first pulse, said pause, and said second pulse,
• wherein the phase-pulse control system is in further electronic communication with a programmable logic controller, the programmable logic controller being further electronically connected to a human machine interface and to a thermal monitor,
• wherein the thermal monitor is further connected to a thermal sensor, said thermal sensor being in contact with the accumulator battery, and
• a remote monitoring and control module (RMCM) connected to the phase-pulse control system, said RMCM communicating a signal outside of the device.
