Title:
SECONDARY-BATTERY TEMPERATURE-RAISING APPARATUS AND VEHICLE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2011/004464
Kind Code:
A1
Abstract:
An apparatus for raising the temperature of a secondary battery (10) comprises a ripple generator (20) and a controller (30). The ripple generator (20), which is connected to the secondary battery (10), is adapted to actively cause the secondary battery (10) to generate a ripple current (I) having a predetermined frequency. The controller (30) controls the ripple generator (20) to cause the secondary battery (10) to generate the ripple current (I), thereby raising the temperature of the secondary battery. Herein, the predetermined frequency is set, based on the frequency characteristic of the impedance of the secondary battery (10), to a frequency in a frequency range in which the absolute value of the impedance relatively decreases.
