Title:
SYSTEM AND METHOD FOR ALLOCATING PROPULSION LOAD POWER DRAWN FROM HIGH-ENERGY BATTERY AND HIGH-POWER BATTERY
Document Type and Number:
Japanese Patent JP2022042993
Kind Code:
A
Abstract:
To provide a system and method for allocating load power drawn from multiple batteries for powering propulsion of a vehicle.SOLUTION: A battery system 11 includes: a high-energy battery 18a and a high-power battery 18b respectively designed for optimal production of DC power during high-specific-energy and high-specific-power propulsion; and battery health management systems configured to monitor the state of charge and the state of health of the batteries and generate battery status signals. The system further includes a propulsion load configured to produce propulsion force using power converted from power generated by at least one of the batteries, and a system controller 12 configured to allocate load power drawn from the high-energy and high-power batteries for use by the propulsion load in accordance with a propulsion phase of the vehicle and the battery status.SELECTED DRAWING: Figure 3
