Development of the detection system is possible by means of an additional ON/OFF terminal on the integrated controller AC/DC. Because of it, this is possible using only a few external elements.

  • Fault notification means detection of error and notification of user about such fact by means of proper signalling.
  • Device is in the idle mode as briefly as possible in order to switch to battery 3 charging. Module consumes maximum power (up to 10 W). When the battery 3 was charged, module switches to power saving mode. In this mode, it stays as long as possible to reduce losses almost to zero. In all three modes the device awaits AC power decay.
  • LiFePC batteries are used internal controllers of which protect them against short-circuiting the cells. Such short-circuit may lead to significant heating of the whole package and to its damage as the best case scenario.
  • Controller is designed so that when the battery is connected to the charger and short-circuit occurs on its terminals which short-circuit both the battery and charger, battery protection activates and cuts off power supplied from it thus protecting it at the same time. When the short-circuit is removed, the controller must detect that it is safe to turn off the protection. Unfortunately, the charger itself is a load also. Even though it is perceived through a very large resistance (order of hundreds of kiloohms), the controller will not activate the battery. The solution turned out to be forcing current flow towards the battery, i.e. initiation of charging with very short pulses which fact effectively resets the package and restarts charging.

After disconnecting a load, the power supply 1 automatically switches to reduced power consumption mode. The control system 15 monitors battery 3 voltage and if its level drops by more than 7% all module functional block are reconnected to the supply, which fact automatically switches the power supply from the reduced power consumption mode to normal operation mode and the battery 3 is recharged. After recharging the package, the control system 15 disconnects the power supply 1 and the aforementioned cycle is repeated.
  • the detection system 8 informs about this fact the control system 15 which causes that the system controls the driver LED DC/DC 9 so that it starts supplying external LED module 13. If the power supply 1 was in the mode of reduced power consumption at the moment LI signal appeared, the control system 15 connects all module functional blocks to the power supply 1 making it to return to normal operation mode. It it this not possible for the power supply 1 to operate in the mode of reduced power consumption during LI signal presence when the module LED 13 is supplied.
  • Testing status can be called only at presence of external AC voltage supply. It can be activated by short-circuiting proper input terminals of the module or automatically by a microprocessor 7. If this mode is called, the control system 15 disconnects the power supply 1 from the remaining functional blocks which fact causes that the switching system 4 starts supplying driver LED DC/DC 9 and current flows to load LED 13.
  • the microprocessor 7 monitors and analyses data sent by measurement block 5. If any of the parameters is out of the limits set by the program, the test is stopped to protect the module and / or battery against possible defect. After the test, its result is saved in EEPROM memory 10 and signalled using red signalling diode 12. Moreover, during the test, green signalling diode 12, informing about battery charging, should turn off. Test can be called regardless of the presence or not of LI controlling signal.
  • the third operation mode of the module i.e. emergency mode is called always when supply input voltage drops to the level specified as 0.6 - 0.9 of the rated supply voltage.
  • threshold detection system 6 Satisfaction of this condition is ensured by threshold detection system 6. Switching the module to emergency operation mode is possible always after power losses, regardless of the mode the module was before and regardless of LI input condition. In case of power loss, the power supply 1 stops working.
  • the control system 15 in cooperation with the switching system 4 supplies voltage from the battery 3 to driver LED DC/DC 9 and in turn it supplies LED module 13. When in this mode, signalling diodes 12 are off, and the control system reduces energy consumption by the remaining functional blocks, by controlling or shutting them off, LED module 13 is supplied for a set time (lh - 3h), depending on configuration and capacity of the battery. Except the control system 15, the switching system 4 watches over so that the battery is not discharged too deeply - when the set threshold is achieved (dangerous for the battery 3) it is disconnected from the load and the consumed power is limited to quiescent current at level of nA.
  • the system automatically switches from the emergency mode to operation from the network mode.
