#CMT# #/CMT# The circuit (20) has a switch (K1) arranged in parallel to terminals of a lithium-ion battery (10), where the switch includes a transistor (K1S1) and a diode (K1S2). Another switch (K2) is arranged in series to one of the terminals of the battery, where the transistor is selected from one of a metal oxide semiconductor (MOS), a FET, an insulated-gate bipolar transistor (IGBT), and a bipolar transistor. An electronic control unit (25) controls the opening of the switches such that the parallel switch is opened with a delay after the opening of the series switch. #CMT# : #/CMT# Independent claims are also included for the following: (1) a rechargeable battery (2) a method for disconnecting a rechargeable battery. #CMT#USE : #/CMT# Disconnection circuit for disconnecting a rechargeable battery i.e. lithium-ion battery for a car and a telecommunication station (all claimed). #CMT#ADVANTAGE : #/CMT# The circuit allows fast disconnection of the battery even under strong currents, and supports a possible inversion of polarity of the battery. The series switch allows charging and/or discharging of the battery to be interrupted, and diode allows inductive loads to be absorbed when opening the series switch while preventing the application of an inverse voltage at the terminals of the battery. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram of a disconnection circuit.'(Drawing includes non-English language text)' K1, K2 : Switches K1S1 : Transistor K1S2 : Diode 10 : Lithium-ion battery 20 : Disconnection circuit 25 : Electronic control unit. |
