Embodiment 1

[0041] Embodiment 1: Applied to light electric vehicle power platform system

[0042] The light electric vehicle has a design speed of 60km / h, adopts a brushless DC motor with a rated power of 7.5W, and uses 24 lithium iron phosphate batteries of 120AH in series for the power battery pack, with a rated voltage of 72V. According to the characteristics of lithium iron phosphate battery, the battery high voltage protection voltage (charge protection and energy feedback protection voltage) is set to 3.8V, the low voltage protection voltage is set to 2.5V, and the low battery alarm voltage is set to 2.8V.

[0043] Such as figure 1 As shown: the light electric vehicle power platform system includes a power battery pack 1, a battery protection board 2, a motor controller 3 and a motor 4; the motor 4 passes through the motor three-phase power line 5, the motor speed signal line 6, and the motor control signal line 7 respectively. Connect with the motor controller 3; the motor control...

Abstract

The invention discloses an electromobile power platform system with integrative control, which comprises a power battery pack, a battery guard plate, a motor controller and a motor, The motor is connected with the motor controller through a motor three-phase power line, a motor speed signal line and a motor control signal line; the motor controller is connected with a positive electrode and a negative electrode of the power battery pack; and the battery guard plate is connected with the motor controller through a low electric quantity alarming signal line, a low voltage protecting signal line and a high voltage protecting signal line for sending low electric quantity alarming signals, low voltage protecting signals and high voltage protecting switch signals to the motor controller. According to the electromobile, the motor controller provides charging protection and discharging protection for the power battery pack, so as to overcome the problem of damage on the battery guard plate and the motor controller by surge current formed due to the fact that the battery guard plate suddenly powers off to protect the power battery pack, the efficiency and the reliability of the system are improved and the cost is reduced.

Description
