Abstract

A battery autoclaving system is provided including a battery pack having a housing, a battery cell disposed within the housing, and an isolation region disposed between the housing and the battery cell. The isolation region may be formed at least partially from at least one of a thermal insulating material, a phase change material or any combination thereof. The system may include a temperature sensor adapted to sense at least one of a temperature of the battery cell temperature of the isolation region, The system may include and an autoclave configured to receive a temperature indication from the temperature sensor and to inhibit autoclaving when the temperature indication exceeds a predetermined value.

First claim

1 - 12 . (canceled)

13 . A battery autoclaving system, comprising:
an autoclavable battery pack, comprising:
a housing;
a battery cell disposed within the housing; and
an isolation region disposed between the housing and the battery cell, the isolation region being formed at least partially from at least one of a thermal insulating material, a phase change material, or a combination thereof;
a temperature sensor adapted to sense at least one of a temperature of the battery cell or the temperature of the isolation region; and an autoclave configured to receive a temperature indication from the temperature sensor and to inhibit autoclaving when the temperature indication exceeds a predetermined value.

14 . The system in accordance with claim 13 , wherein the isolation region further comprises at least two layers, wherein each layer is formed from at least one of a phase change material or an insulation material.

15 . The system in accordance with claim 13 , wherein the isolation region is formed from two or more materials selected from the group consisting of one or more of a phase change material and an insulation material.

16 . The system in accordance with claim 13 , wherein the battery pack further comprises a sterile terminal cap configured to selectively cover at least one of the first or second outer terminals.

17 . The system in accordance with claim 13 , wherein the battery cell is a Li-ion battery cell.
