PASSIVE ARCHITECTURES FOR BATTERIES HAVING TWO DIFFERENT CHEMISTRIES |
| 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. |

1. A 12 volt automotive battery system, comprising:
a first battery configured to be directly coupled to an electrical system, wherein the first battery comprises a first battery chemistry; and a second battery coupled in parallel with the first battery and configured to be directly coupled to the electrical system, wherein the second battery comprises a second battery chemistry with a higher coulombic efficiency than the first battery chemistry, the first battery and the second battery being non-voltage matched such that a voltage range of the second battery is higher than a voltage range of the first battery; wherein the first battery is configured to steer 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 is configured to provide 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. |
