Claim:
1. A power battery system, comprising: a number of parallel groups that being connected in series, each of the parallel groups comprising a number of single batteries connected in parallel; a number of electrode boards, each of the electrode boards being electrically connected between two neighbored parallel groups; wherein each of the electrode boards comprises a number of electrode contact plate, a conductive substrate, and a number of security devices; each electrode contact plate is configured for being electrically connected to two neighbored single batteries of the two neighbored parallel group in series; each of the security devices corresponds to an electrode connection plate and electrically connects an electrode connection plate to the conductive substrate; each of the security devices fuses when one of the single battery occurs short circuit, wherein the power battery system further comprises a number of dielectric members made of dielectric material; each of the dielectric members is annular and surrounds an electrode contact plate; each electrode contact plate is isolated from the conductive substrate by a dielectric member.
