Assignee:

Johnson Controls Technology Company - Plymouth MI

International Classification:

H02J 700
H02J 712

US Classification:

320104

Abstract:

A control circuit for controlling the recharging of two batteries in a dual battery vehicle electrical system includes a charging circuit (20) for stepping up the voltage of a reserve battery (RES. ), so that it can be applied to a starting battery (HPB), an alternative circuit path (18, 19) to allow charging of both batteries by the alternator (A) when the vehicle engine is running, and a controller (30) for switching the connection of the batteries through the charging circuit (20) and the alternative circuit path (18, 19) under various combinations of conditions.

International Classification:

H01M 1044
H01M 1046

US Classification:

320132

Abstract:

A method and apparatus for determining the state of charge of a battery include use of multiple battery tests to provide complementary insight into battery condition before, during, and after battery charging. Battery testing is performed using a light resistive load, a heavy resistive load, a conductance tester, and a battery charger. During a preliminary charging stage, average battery current and a predicted battery temperature are used to determine whether or not the battery is capable of being substantially fully charged, thereby permitting avoidance of unneeded charging. In the later charging stage, the rate of change of battery cold cranking amps is monitored to detect an end of charge condition.

Appl. No.:

8/932950

Inventors:

Thomas J. Dougherty - Waukesha WI
William P. Segall - Grafton WI
Michael E. Iverson - Milwaukee WI

Assignee:

Johnson Controls Technology Company - Plymouth MI

International Classification:

H02J 700

US Classification:

320104

Abstract:

An electrical system of a vehicle has a starting battery and a reserve battery. The charge of the starting battery is maintained by a charge maintenance device under control of a controller which couples energy from the reserve battery to the starting battery during periods when the vehicle is not being used or during periods of operation where the starting battery voltage requires additional charge.

Appl. No.:

9/204207

Inventors:

Thomas J. Dougherty - Waukesha WI
William P. Segall - Grafton WI
Michael E. Iverson - Brown Deer WI

Assignee:

Johnson Controls Technology Company - Plymouth MI

International Classification:

H01M 1044

US Classification:

320104

Abstract:

Battery powered equipment is provide with a controller which monitors the voltage supplied by the battery. Should the battery voltage drop below a preset level when the equipment is inactive, the controller disconnects non-essential loads of the equipment from the battery to conserve what charge remains in the battery. When used with a motor vehicle the controller may be tied into the security system and disable the ignition during inactive periods unless the proper reactivation signal is received.
