摘要： A method for maximizing the availability of start-stop operations within a microhybrid vehicle includes determining the electric current drawn by a set of electrical components of the vehicle, from the vehicle's battery. The internal resistance of the vehicle's battery, and the resistance of a starter motor loop circuit coupled to the engine of the vehicle are dynamically calculated. The closed-circuit voltage of the battery is predicted, using the internal resistance of the battery, the resistance of the starter motor loop circuit, and the current drawn by the set of electrical components of the vehicle. The start-stop operation is carried out if the closed-circuit voltage of the battery is predicted to be above a pre-determined minimum value.

摘要： A vehicle determines a first resistance of a starter motor and a starter cable connected thereto based at least in part on the first voltage of a power source. The vehicle determines a predicted minimum battery voltage based at least in part on the first resistance of the starter motor and the starter cable. The vehicle, in response to the predicted minimum battery voltage satisfying a threshold, enables a vehicle stop-start function, and, in response to the predicted minimum battery voltage failing to satisfy the threshold, disables the vehicle stop-start function.

摘要： A passive two-terminal circuit element may include a resistor including a carbon-metal composite resistive element. The resistive element is configured to maintain a resistivity that fluctuates less than one tenth of an ohm per ten degree temperature change up to 400 degrees Celsius.
