H02J 7/00
H01G 9/26

Abstract:

A vehicle power system includes loads, a battery coupled to the loads, an ultra-capacitor coupled to the battery, and a bypass circuit. The loads, the ultra-capacitor, and the battery are electrically coupled in series. The bypass circuit monitors the ultra-capacitor and prevents the ultra-capacitor from over-discharging and reversing in polarity

Inventors:

- Dearborn MI, US
David Celinske - Wolverine Lake MI, US
John Anthony DeMarco - Lake Orion MI, US

International Classification:

B60L 11/18
G01R 21/133
B60W 50/04
G05B 19/042
G01R 31/36

Abstract:

Method and apparatus are disclosed for energy-consumption detection of vehicles in an off state. An example vehicle includes a controller area network (CAN) including CAN buses, a gateway module, and electronic control units (ECUs) that are each connected to one of the CAN buses. Upon activating while the vehicle is in an off state, a first of the ECUs sends a message via a corresponding one of the CAN buses to activate the gateway module. The message includes activation data and the gateway module stores the activation data.
