If it is a top-up ETC, you can go to the ETC service center to recharge, or log in to the local high-speed official website, find the ETC top-up and recharge according to the operation. One thing to note is that you look at your ETC card is written on the stored value card or accounting card, if it is a stored value card, you must go to the ETC service center to circle after recharging in order to normal use.
