ADAPTIVE ELECTRONIC SWITCH OF BATTERY Russian patent published in 2012 - IPC H02H7/18 

FIELD: electrical engineering.

SUBSTANCE: adaptive electronic switch in a battery relates to electrical equipment used in transport and may be used for automatic disconnection of the battery in case of equipment damage and in emergency situations. The invention focuses on a negative battery terminal being connected to the field transistor having its drain coupled with ground through polyswitch, a control gate is connected via resistor to the source and voltage sensor coupled with the battery. To ensure operation of computers, radio transmitters and security alarm, the field transistor is interlocked by polyswitch, meaning that during vehicle parking, the battery becomes low and may be discharged completely. To avoid low battery situation, a special device is actuated at 75-85% of charge capable of disconnecting battery from discharging. Small dimensions of field transistors provide for their placement in grounding connection wiring.

EFFECT: improved reliability.
