Design of Mild Hybrid System with RICOH Power Management IC
48 V mild hybrid system is one of the options to cope with electromobility which is accelerated by the CO2 emissions regulations.
Compared with the strong hybrid system using high voltage, the mild hybrid system can be less expensive and easily mounted on vehicles.
Also, compared to the current 12 V system, the mild hybrid system has been put into practical use in Europe to improve system efficiency and reduce the size and simplify the parts.
Hybrid system comparison
| Weight | Motor | Battery | Electric Mode Driving | Cost | |
|---|---|---|---|---|---|
| Mild Hybrid | Light | Small | Small | No | Less Expensive |
| Strong Hybrid | Heavy | Big | Big | Yes | Expensive |
Direct power supply from 48 V battery
In order to support the design of your mild hybrid system, RICOH has a range of products with operation up to 60 V (maximum rating 80 V). Simple system configuration is realized by supplying power directly from 48 V battery.
R1560 / R1561 / R3160 combines the features of RICOH, low current consumption, fast transient response, and high precision.
