Abstract
A deceleration control method and system for an electric vehicle that performs deceleration by hydraulic pressure braking when a battery of the electric vehicle is in a fully charged state while coasting. The deceleration control method for an electric vehicle includes determining whether the electric vehicle is coasting, comparing a coasting speed with a predetermined creep speed when the electric vehicle is coasting, calculating an amount of regenerative power generation corresponding to the coasting speed when the coasting speed is higher than the predetermined creep speed, comparing the calculated regenerative power generation amount with a chargeable power amount of the battery, and generating predetermined hydraulic pressure braking torque when the calculated regenerative power generation amount is higher than the chargeable power amount of the battery.
