摘要:
A 12 volt automotive battery system includes a first battery directly coupled to an electrical system, in which the first battery includes a first battery chemistry, and a second battery coupled in parallel with the first battery and directly coupled to the electrical system, in which the second battery includes a second battery chemistry with a higher coulombic efficiency than the first battery chemistry. The first battery and the second battery are non-voltage matched such that a voltage range of the second battery is higher than a voltage range of the first battery. The first battery steers power generated during regenerative braking to the second battery using internal resistance of the first battery to enable the second battery to capture a majority of the power generated during regenerative braking, and the second battery provides power to the electrical system due to the higher voltage range of the second battery when the second battery has a positive state of charge.
