Title: Time-controlled battery heating regulator - for heating vehicle starting battery
Inventor: BENISCH JUERGEN
IPC: B60R16/03
Filed: 1992-05-18
Abstract: In a vehicle starter battery heating regulator consisting of eight bistable multivibrators (flip-flops 1-8) and two monostable multivibrators (9-10), the novelty is that four different negative input voltage (11) and a 12V positive/negative input voltage (V2) are connected through the various multivibrator circuits so that a time-shifted potential is periodically produced at the circuit output (13) for controlling battery heating, resulting in activation of battery heating only at a certain moment and for a certain duration. Thus, partially time-shifted battery heating is initially set by the consumer and not by the vehicle dealer or manufacturer to achieve the desired battery starting power and the desired switching state during operation, so that controlled battery heating is possible and is switched on after a 30 sec. delay after initiation of a starting operation. Pref. the circuit is encapsulated in a cast epoxy resin or plastics mixt. or in welded plastic foil so that it can be fitted acid-tightly at any position in the battery. ADVANTAGE - The battery heater is initially activated by the new battery or vehicle purchaser, is switched off for 30 sec. on vehicle starting so that the starting operation is not additionally loaded by the heater, is activated even after vehicle starting until the battery has reached the desired internal temp. and allows more rapid battery charging.
