技術簡介

一種電池組和以其熱電特性控制電池組充放電的方法，其中的電池組具有數個溫度範圍區。這個電池組包括數個並聯電池組以及數個可變電阻，每個並聯電池組分別位在各個溫度範圍區，且每一並聯電池組是由數個單電池並聯而成。可變電阻則位於兩兩並聯電池組之間，以減緩因每一並聯電池組的工作溫度、殘餘電量造成不同電位特性導致電池組使用壽命減少的問題。

Abstract

A battery pack and a method of controlling charge-and-discharge of the battery pack by its thermoelectric property are provided in which the battery pack has a plurality of temperature range regions. This battery pack contains a plurality of parallel-connection battery groups and a plurality of variable resistances. The parallel-connection battery groups are dislocated in each of the temperature range regions respectively, and each of the parallel-connection battery groups includes battery cells connected in parallel. The variable resistances are disposed between two parallel-connection battery groups in order to slow down the problem in decreased lifetime of the battery pack caused by different potential properties due to working temperature and residual current of each of the parallel-connection battery groups.

技術規格

適用於現今所有動力型電池pack

Technical Specification

none

技術特色

(1)允許電池pack內有不同特性的電池組成。 (2)允許電池pack內的模組老化程度可不同，但不影響壽命。 (3)成本可因不需強調pack電池均一性而下降。
