Abstract

A synergistic system made up of a control unit having the function of identifying and monitoring the battery, and transmitting the information regarding the actual state of its energy conditions to a battery charger, made to attain energy saving and well as a greater functionality and efficiency of the identified battery.

Claims

1. Synergistic system between battery charger and battery made for identifying and monitoring the operation data of the battery to be charged so as to reduce energy consumption and obtain greater functionality and efficiency of the charge cycle and of the battery identified characterised by an identification and monitoring module interacting with a microprocessor used to memorise all operation and maintenance parameters of the battery:

such as voltage, current, temperature and level of equalisation which, each time the battery is connected to the battery charger, are connected to a technical solution system of the battery charger subject of the present patent application which, interacting with each other, adapt the charge cycle to the actual efficiency and maintenance state of the identified battery hence ensuring maximum energy efficiency over the entire charge cycle, including the final one, automatically adjusting and automatically compensating any power supply voltage variations in such a way to reduce the heat that is normally generated in the final charging phase leading to further increasing the efficiency of the same identified battery and considerably reducing the energy consumption of the entire charge cycle.

2. Synergistic system between battery charger and battery according to claim 1 wherein said identification and monitoring module installed on the battery is characterised by a microprocessor inserted into a sealed container in such a way to resist against acid corrosion, against water and vibrations and it is made up of an electrical circuit used to memorise and transmit all the operation parameters to a technical solution system which, interacting with each other, adapt the charge circuit to the actual efficiency and maintenance condition of the identified battery ensuring maximum energy efficiency and good maintenance thereof.

3. Synergistic system between battery charger and battery according to claim 1, characterised in that the identification and monitoring module with the microprocessor also serve to prevent the battery from being damaged by thermal leakage sending a pre-alarm signal with the value of the measured temperature, in such a way that the battery charger interrupts the previously calculated high power pulse beforehand or provides for the replacement thereof with a low power pulse and also memorises the malfunctions that might have occurred during the various charge phases of the same battery in such a way to avoid, during the subsequent charging operations on the same battery, the reoccurrence of the malfunctions observed in the previous charge cycles.

4. Synergistic system between battery charger and battery according to claim 1, characterised in that the identification and monitoring module is supplied with power directly by the battery and exploits the power line communication technology in such a way to avoid the addition of supplementary cables.

5. Synergistic system between battery charger and battery according to claim 1, whose identification and monitoring module is characterised by a password for the activation thereof and by a block and anti-tempering system.

6. Synergistic system between battery charger and battery according to claim 1, characterised by a set of battery charger technical solutions made up of a twelve-pulse frequency multiplying system, a static power factor correction system with capacitors, a pulse end-of-charge system which, interacting with each other and with the identification and monitoring module and the microprocessor, compensate any power supply voltage variations, including the final charge phase, automatically regulating them to the parameters of the battery being charged regarding voltage, current, temperature and level of equalisation, in such a way to have a considerable reduction of energy consumption and greater heat dispersion required to eliminate the battery stress in such a way to increase the energy efficiency and duration thereof.

7. Synergistic system between battery charger and battery according to claim 1, whose twelve-pulse frequency multiplying system and static power factor correction system are characterised in that they respectively raise the distortion and power factor correction factors to a coinciding value of 0.99 in such a way to allow the power factor required to obtain the maximum energy efficiency of the charge cycle.

8. Synergistic system between battery charger and battery according to claim 1, whose final charge system, interacting with the identification and monitoring module of the battery and the microprocessor, is characterised in that it compensates any power supply voltage variations automatically adjusting them to the efficiency and maintenance parameters of the battery being charged, said parameters being made up of voltage, current, temperature and level of equalisation in such a way to reduce the energy consumption of the charge operation and have greater heat dispersion required to protect the battery increasing energy efficiency and duration thereof.

9. Synergistic system between battery charger and battery according to claim 1, whose twelve pulse frequency multiplying system is characterised in that it is provided with a nine-coil three-phase transformer with flow dispersed by partial overlapping of layers, a double full-wave three-phase rectifier bridge and an interphone reactance which has the purpose of levelling the currents that circulate on the rectifier bridges in such a way to reduce the operation temperature and filter the current supplied by the battery charger in such a way to render it perfectly direct.

10. Synergistic system between battery charger and battery according to claim 1, whose static power factor correction system with capacitors is characterised by a three-phase static power factor correction bank connected on the primary of the fixed capacity transformer and by capacitors which can be three or multiples of three and they can be star-connected or triangle-connected.

11. Synergistic system between battery charger and battery according to claim 1, whose pulse end-of-charge system is characterised by a double input contactor which allows varying the transformation ratio of the transformer by automatically adjusting the end-of-charge current pulses, the pause time of each pulse and the total number of pulses to be used on the technical parameters of the battery being charged transmitted by the microprocessor.

12. Synergistic system between battery charger and battery according to claim 1, characterised in that in order to adapt the charge curve to the operation parameters of the battery, the battery charger may operate on two different power levels identifiable as low power and high power, using the low power at the beginning of the charge and until the battery reaches a preset voltage value, after which the charging proceeds using high power pulses interrupted by pauses that are interrupted by the battery charger depending on the parameters read by the microprocessor, also including the possibility to interrupt the pulses to protect the battery in case excessive temperatures are reached.
