Appeal No. 1997-3237
Application 08/266,081
is supplied by operating the motor at reduced efficiency when
the battery is at or near fully charged level.
Representative independent claims 1 and 6 are reproduced
as follow:
1. A method for controlling regeneration energy from an
electric motor, said electric motor having a stator and a
rotor, said method comprising the steps of:
(a) operating said electric motor in a regeneration mode
at a first operating point; and
(b) operating said electric motor in a regeneration mode
at a second operating point of reduced efficiency with respect
to said first operating point in response to a regeneration
current generated by said electric motor.
6. A method of controlling regeneration energy from an
electric motor, said electric motor having a stator and a
rotor, said method comprising the steps of:
(a) operating said electric motor in a regeneration mode
at a first operating point;
(b) providing a battery to receive regeneration current
from said motor;
(c) operating said electric motor in a regeneration mode
at a second operating point of reduced efficiency with respect
to said first operating point in response to a regeneration
current flowing into said battery and a variable representing
a state of charge of said battery.
