LOW VOLTAGE ADAPTIVE BATTERY CHARGER FOR THE SIMULTANEOUS CHARGING OF ELECTRIC DEVICES FOR THE TRANSPORT OF PEOPLE AND /OR GOODS
Field of the art to which the invention refers
The field of the art to which the present invention refers is that of recharging electric devices, in very low voltage, for the transport of people and/or goods.
State of the pre-existing technique concerning the field of reference of the invention
The chargers today used for charging electrical devices, in very low voltage (24 - 36 - 48 V), for the transport of people and/or goods, allows the recharging of a single type of device, characterized by a unique value of voltage and intensity of the charging current
These devices, designed to deliver a predetermined charging current by voltage and intensity level, can therefore be used only for devices characterized by the same charging current.
Invention details and advantages introduced with respect to the pre-existing technique
The main object of the present invention is to provide a device for recharging electrical devices for transporting people and/or goods, able to simultaneously charging a plurality of units, different for values of nominal voltage of battery (24 - 36 - 48 V) and for current intensity.
The present invention is in feet able to automatically adapt the charging current supplied to the voltage value and intensity of the electric device to be recharged.
When the electrical device joins the battery charger, using an AGC junction/connection device, mechanical (male - female) or wireless (transmitter - receiver), a SCM communication sheild, equipped with a programmable logic controller, connected to the fixed part of the AGC, reads the value of the voltage Vin and of the current intensity Iin of battery.
Thanks to digital and/or electromagnetic and/or resistive and/or rfid sensors implemented in the AGC, in addition to the information about the voltage Vin and the intensity Iin, the device ID can also be transmitted when the device is connected.
An SCL control shield, equipped with a programmable logic controller to which the SCM communication shield is connected, processes the information received (Vin, Iin and additionally the ID) associating them with a predetermined type of battery (24 - 36 - 48 V) characterized by a specific charging current for voltage and intensity.
The SCL control shield so drives the PMR modular charging platform, implementing at least one CBT charger (24 - 36 - 48 V), for regulating the charging current and supplying it with the right voltage and intensity, consistently with the associated electrical device (24 - 36 - 48 V).
A direct line LD between PMR and AGC so allows the charging current, with the right value of voltage and intensity, to reach the battery of the associated device.
A PA power plate connects the invention to the electrical network.
The invention is therefore able to adapt the charging current to the voltage and intensity of the electrical device to be recharged. When the electric device is connected, the invention automatically reads the information concerning the device and consequently regulates, in real time, the value of the voltage and the intensity of the current to be supplied. The invention can
therefore recharge, simultaneously devices equipped with batteries characterized by different values of voltage and intensity.
Description of the drawings
Fig. 1 shows the invention in question, equipped with n. 3 recharging points, indicating the abbreviations used previously.
Description of cm application of the invention
Fig. 2 shows an application of the subject invention. In this case the chargor is implemented in a charging column anchored to the ground with n. 8 AGC function/connection devices.
By interfacing with a CB on-board computer, which oversees the rental functions (authorized user recognition, device release and start of the rental session, closing of the rental session, etc...), this implementation allows the realization of sharing mobility platforms characterized by heterogeneous fleets, consisting of different devices for the transport of people and/or goods (e-bike EB, electric scooters SE, electric scooters ME, golf cars GC, personal transporters PT, mobility scooters MS, trolleys electric CE, electric forklifts ME, mobile robots RM).
Measured the value of the voltage Vin and the intensity of the charging current of the battery and additionally the ID of the device through the AGC junction apparatus (mechanical or induction), the SCM communication shield transmits the information to the control shield SCL.
The software implemented in the SCL programmable logic controller processes the information and drives the PMR modular charging platform for regulating the charging current (voltage and current intensity) in line with the electrical device to be recharged (24 - 36 - 48 V).
Using a direct line LD, the charging current then reaches the AGC junction/connection device and from this to the battery to be recharged
