A rotor assembly cooling system (100) and method of using same are provided.
A portion of the rotor shaft (103) is hollow, the rotor shaft including an
open end (107) and a closed end (105). A coolant feed tube (109) is rigidly
attached to the rotor shaft (103) using one or more support members (111),
thus causing the shaft and the feed tube to rotate at the same rate. Coolant
is pumped through the feed tube until it exits the end of the feed tube and
flows against the inside surface of the closed end of the rotor shaft
causing the coolant to change direction and flow back through the coolant
flow region, this region being defined as the space between the outer
surface of the feed tube and the inner surface of the hollow rotor shaft | H*****D

Mitigation of propagation of thermal runaway in a multi-cell battery pack
A method of mitigating propagation of a thermal event in an energy storage
system having a plurality of cells is disclosed. The method includes the
steps of identifying the heat sources within the energy storage system and
plurality of cells. The method then controls a temperature of the energy
storage system and plurality of cells and also detects predetermined
conditions within the energy storage system. The method then performs a
predetermined action based on when one of the predetermined conditions is
detected. A plurality of sensors and switches along with associated hardware
or software will be used to control the temperature of the energy storage
system upon detection of predetermined conditions involving overheating,
over current, over voltage of the like.

BATTERY PACK THERMAL MANAGEMENT SYSTEM
A battery pack thermal management system for use in an electric car. The
battery pack thermal management system includes a plurality of thermistors
connected to a plurality of cells of a battery pack. A battery monitor board
is connected to the thermistors. The system also includes a manifold and a
plurality of cooling tubes connected to the manifold. A tube seal plug is
arranged over an end of the cooling tube and an end fitting is arranged on
an end of the cooling tube. The thermal management system will cool the
battery pack to predetermined temperatures to increase the longevity of the
battery pack within the electric vehicle.

METHOD OF DEACTIVATING FAULTY BATTERY CELLS
A method and apparatus for deactivating a bad battery cell from a battery
pack for an energy storage system of an electric vehicle is disclosed. The
apparatus and methodology includes a clamshell member arranged at an end of
the cells and a printed circuit board arranged adjacent to the clamshell
member. A collector plate is arranged adjacent to the printed circuit board
and a switch is arranged on the printed circuit board. A wire bond is
arranged between the switch and one of the cells and a second wire bond is
arranged between the switch and the collector plate. The plurality of
switches will allow for the identification of the one individual cell having
a weak short circuit within the battery pack. Upon identification of the
cell with the weak short circuit that cell will have its switch placed in an
open position thus electrically isolating the faulty or bad cell from the
battery pack. |
