Rectangular electro-chemical energy source e.g. high voltage battery, in electromotive vehicle e.g. hybrid vehicle, has temperature sensor arranged within energy source for detecting operating temperature and expanded in spatial dimension

摘要

The source (10) has a temperature sensor arranged within the energy source for detecting an operating temperature. The temperature sensor is expanded in a spatial dimension and is formed from a flexible wire element, a band element and/or surface element. The expanded temperature sensor is wound around individual cells or modules or groups of cells or modules. A housing (101) is provided for accommodating of cells e.g. batteries or fuel cells.
