Lithium ion battery system for use in drive system of motor car, has fuse and/or switching unit switched in series to battery modules in strands and adapted to uncouple strand or portion of strand from parallely connected strands
Lithium ion battery system for use in drive system of motor car, has fuse and/or switching unit switched in series to battery modules in strands and adapted to uncouple strand or portion of strand from parallely connected strands
The system (20) has battery modules (17) comprising a battery cell (16) and switched in series between a load-side end (12) and a load-far end (10) of parallely connected strands (18). One of the battery modules is switched into series to the strands. The load-side end of the strands comprises an energy storage unit (15) that is switched in series to the battery modules. A fuse (6) and/or a switching unit (8) are switched in series to the battery modules in the strands and adapted to uncouple the strand or a portion of the strand from the parallely connected strands. The switching unit is designed as a contactor, a relay and a MOSFET. The energy storage unit is designed as an inductor.
