We study the higher-order nonclassical properties and the intermodal entanglement of the even and odd nonlinear charge coherent states. We derive the analytic expressions of the higher-order antibunching, higher-order squeezing and higher-order entanglement. We show that these states exhibit antibunching to all orders and the antibunching exists depending on the variables, especially on the nonlinear functions. We also show that in such states, the higher-order squeezing appears only in the even orders and the degree of squeezing depends on the nonlinear functions. Furthermore, it is proved that these states are two-mode entangled.
