Benefits of technology

[0009]Further, a system for managing thermal conditions of an energy storage module is disclosed. The system comprises a pump for providing coolant flow, a valve configured to receive signals from a controller and to control the coolant flow. The controller is configured to receive a first temperature from a first temperature sensor in an energy st

Problems solved by technology

Shock and vibration are problematic when packaging energy storage cells into an energy storage module.
Such movement can break inter-cell connections or wear through the protective case of the cell.
Excess heat or a manufacturing defect can lead

Embodiment Construction

[0019]The present disclosure relates to an energy storage module 10 as shown in FIG. 1. The energy storage module 10 secures energy storage cells 30 in a manner suitable for use in harsh environments or heavy duty mobile applications.

[0020]The energy storage cells 30 could be battery cells or capacitors, particularly ultracapacitors.

[0021]Energy storage packages are commonly used in electric drive vehicles, hybrid vehicles, and stationary power generators. In electric drive applications, the energy storage package stores energy from deceleration and provides power for traction motors in order to propel a vehicle. In hybrid applications, the energy storage package stores energy from deceleration and augments an engine in providing power in order to propel a vehicle. In stationary power generator applications, the energy storage package can be used to augment the primary engine and generator. Large amounts of power are charged to and discharged from the energy storage package in these...

Abstract

The present disclosure relates to cooling an energy storage module using passive and active cooling techniques. Passive cooling is provided by storing heat in a phase change material that is contact with the energy storage cells of the energy storage module. Active cooling is provided by circulating coolant through coolant passages that are in thermal contact with the energy storage cells. A control system for determining the temperature of the energy storage module and controlling coolant flow when the temperature reaches a predetermined threshold is disclosed.

Description

TECHNICAL FIELD[0001]The present disclosure relates cooling an energy storage module, and more particularly, an energy storage module equipped with coolant passages and a phase change material.BACKGROUND[0002]Energy storage modules are increasingly used in mobile and stationary applications. Uses include hybrid and electric drive vehicles, as well as stationary power generation. The modules usually contain battery or ultracapacitor cells as a way of storing electrical energy for long periods of time, and / or rapidly charging or discharging as needed. The charge / discharge process quickly generates a large amount of heat, which should be managed. Also, the performance and life of the cells depends upon their temperature. Therefore, the steady state temperature of the cells should be managed.[0003]A further requirement of the energy storage module is that it is capable of operation when exposed to harsh environments. Shock and vibration are problematic when packaging energy storage cell...
