Image Credit: Kia.Imagine plugging in your EV for a small top-up, adding less than 5 kWh of electricity, and eventually receiving a bill large enough to buy another car. That's essentially what happened to one Kia EV9 owner in Canada after a routine charging session produced an extraordinary invoice.The owner, who goes by IntelliDev on Reddit, says Hypercharge Networks billed them CAD$22,308, or roughly US$16,000. Making matters stranger, the EV9 had consumed only 4.91 kWh during the session, an amount of electricity that should have cost only a few dollars.There was obviously something very wrong with the calculation. A closer look at the invoice revealed some unusual dates and an important message concerning the charging terminal, providing a major clue as to how such an enormous bill could have been generated.AdvertisementAdvertisementThe owner contacted Hypercharge to dispute the charge, and there's now an update to the story. Fortunately, nobody had to empty their savings account to pay for 4.91 kWh of electricity.One Charging Session Apparently Lasted 15 MonthsThe original invoice shows the EV9's charging session beginning at approximately 6:57 p.m. on May 17, 2025. According to Hypercharge's records, however, it didn't end until around 1:09 p.m. on August 25, 2026.That's a period of roughly 15 months. The EV9 obviously wasn't physically connected to the charger that entire time, and the tiny 4.91-kWh energy total makes that even clearer.The invoice contained another revealing detail, stating that the historical session had taken place at a terminal that was "out of communication." That suggests the charger or network failed to correctly record when the actual charging session ended.Where The CAD$22,308 Came FromThis particular charger appears to have billed customers according to time rather than strictly by the amount of electricity delivered. With an hourly rate of approximately CAD$2, an electronically active charging session lasting over a year can suddenly produce some frightening arithmetic.AdvertisementAdvertisementThere's another strange discrepancy. Although the start and end dates span one year, three months, and several days, the displayed session duration reportedly shows only seven days, 18 hours, 12 minutes, and 40 seconds.The billing calculation nevertheless appears to have accounted for the much longer period. In other words, the system seemingly forgot part of the duration when displaying it while remembering those missing months when calculating how much money was supposedly owed.The EV9 Owner Challenged The BillUnsurprisingly, IntelliDev wasn't prepared to hand over CAD$22,308 without asking questions. The owner contacted Hypercharge and disputed the invoice, bringing the bizarre charging session to the company's attention.There are plenty of stories where companies have made a mistake and then dug their heels in when it's pointed out. Would Hypercharge immediately recognize the obvious error, or would the customer have to spend days fighting an automated billing system over a five-figure charge?AdvertisementAdvertisementFortunately, Hypercharge responded, acknowledged the situation, and corrected the erroneous bill, bringing the owner's extremely expensive charging session back down to reality.Hypercharge Made Things RightThe resolution didn't stop with simply removing the five-figure charge. According to IntelliDev's subsequent Reddit update, Hypercharge also refunded the legitimate charging cost and provided CAD$50 in charging credit as a goodwill gesture.That response changes the tone of the story, as Hypercharge appears to have dealt with the customer appropriately once the problem was brought to its attention.There's also no evidence that the Kia EV9 itself caused any part of the problem. Everything available points toward an issue involving the charging terminal's communication and subsequent billing rather than anything unusual happening aboard the vehicle.AdvertisementAdvertisementA five-figure invoice probably wasn't what this EV9 owner expected when plugging in for a few dollars' worth of electricity. At least the story ultimately ended with the bill corrected, some free charging credit, and one spectacular example of why automated billing systems occasionally need a human sanity check.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
