Abstract
A battery management apparatus includes at least one capacitor respectively connected to at least one battery and a controller configured to apply current to the at least one capacitors to pre-charge the at least one capacitors, measure a voltage of each of the at least one capacitors, and control impedance measurement of the at least one batteries based on whether the voltage of the at least one capacitors is within a threshold range.
Claims14
A battery management apparatus comprising:
- one or more capacitors, each capacitor of the one or more capacitors connected to a respective battery among one or more batteries;
- and
- a controller configured to apply current to each of the one or more capacitors to pre-charge the one or more capacitors, measure a respective voltage of each of the one or more capacitors, and, for each battery of the one or more batteries, control an impedance measurement of the battery based on whether the voltage of the capacitor connected to the battery is within a threshold range.
