<p>PCT No. PCT/EP92/02930 Sec. 371 Date Jun. 21, 1994 Sec. 102(e) Date Jun. 21, 1994 PCT Filed Dec. 17, 1992 PCT Pub. No. WO93/13568 PCT Pub. Date Jul. 8, 1993.A battery heating device includes a temperature sensor and at least one heating element in a liquid and acid-proof arrangement inside the battery. The heating element is a power transistor secured to a cooling plate which is powered by the battery, the emitter of the power transistor being powered by a temperature control circuit when the battery temperature falls below a predetermined reference temperature and the battery voltage is higher than a lower threshold and lower than a higher threshold. A trigger circuit responds to a rise in battery voltage after the current in a load having a high current consumption is switched off. The trigger circuit actuates a timer circuit which conductively controls the power transistor for a set time if the battery voltage is under or at the lower threshold.</p> |
