Abstract
A limited protection method for charging/discharging current of hybrid electric vehicle battery and a device and a system thereof is disclosed. Said method includes: receiving a power requirement and determining an original torque based on the power requirement; judging a charge/discharge state of the battery and acquiring a limited torque from an actual current and a predefined torque; comparing said original torque with the limited torque to select the smaller one as a final output requirement. The embody of the invention can achieve the real-time limited protection for charge/discharge current of hybrid electric vehicle battery.
