Battery life monitor and battery state of charge monitor
InactiveUS20050017685A1Accurate readingBatteries circuit arrangementsElectrical testingBattery state of chargeEngineering
The electrolyte inside a lead and acid battery is inaccessible and measurements of the voltage across a battery's terminals do not necessarily give a good indication of the future performance of a battery. Furthermore, although the state of charge of a battery can be determined from measurement of the voltage across its terminals, these measurements will be misleading unless they are taken when the battery is in equilibrium. Accordingly, the present invention proposes a battery monitor which takes measurements from a battery and is configured to detect one or more types of event affecting the battery life and to subtract a predetermined amount from a life counter representing the remaining available life of the battery, each time such an event is detected. The monitor is also configured to calculate the state of charge of the battery, but only when the battery is in equilibrium.

In a control apparatus for a hybrid vehicle which is able to travel under the driving force from at least one of an internal-combustion engine E and a drive motor connected to the internal-combustion engine, when an FI / AT / MGECU and a MOTECU execute motor damping which generates a torque for suppressing the torque vibration of the internal-combustion engine, in the motor M, the MOTECU corrects a motor torque calculating battery terminal current value obtained by multiplying an input-output current ABAT of the battery, by an offset value corresponding to the motor damping, and executes zero power control based on the corrected motor torque calculating battery current value. As a result, the input and output power of the power storage unit are accurately balanced and overcharge or overdischarge of the battery based on the input-output current ABAT of the battery including errors due to the damping control or the motor torque calculating battery current value, is avoided.
