Hello, I'm glad to answer your question. Different charging piles have different refund methods. My answer to this question is this: regarding recharge and refund, it depends on the charging mode of the charging pile you use. Generally, after charging, the rest can be refunded, some can be returned directly (there may be some delay), and some can be returned to your charging account, and then recharged next time or applied for a refund.
However, in some cases, you can't apply for a refund. For example, if you buy a charging package, it has been converted into package interest, which is generally non-refundable. Specifically, you can call the service phone above the charging pile and ask the manual customer service.
