Abstract
A daisy-chain battery cells system having a plurality of differential communication interfaces {F(i), i=1, . . . , N} respectively coupled to a plurality of voltage measuring modules {S(i), i=1, . . . , N} for a plurality of battery cells {C(i), i=1, . . . , N}. For each i=1, . . . , N−1, a first high side differential pin pair (CLU(i)+, CLU(i)−) of the idifferential communication interface F(i) is coupled to a first low side differential pin pair (CLL(i+1)+, CLL(i+1)−) of the (i+1)differential communication interface F(i+1), and a second high side differential pin pair (DAU(i)+, DAU(i)−) of the idifferential communication interface F(i) is coupled to a second low side differential pin pair (DAL(i+1)+, DAL(i+1)−) of the (i+1)differential communication interface F(i+1). A low side interface FL(1) of the first differential communication interface F(1) is coupled to a controller. A high side interface FU(N) of the Ndifferential communication interface F(N) may receive a preset data/signal.
