Charging account and emergency call
Monta account compromised: 20 charges at 100 euros each
New topic · 46 replies · 9 participants
A member reports that his Monta account’s email address and IBAN were changed. Subsequently, 20 transactions of 100 euros each were loaded into his wallet from the credit card he had saved via Google Pay, allegedly within seconds at night. Additionally, an attempt was made to withdraw 1,000 euros to a Belgian account. In Monta’s response, which he quoted on the forum, it states that there are no signs of a security incident at Monta; the password apparently was already known to the attacker, likely from a data leak from another service. The transactions were reversed, the withdrawal was stopped, and implementing a PIN requirement for deposits is underway. On October 21, he reported that the 20 payments had been refunded.
The way the attacker gained access to the account remains unclear. Several members suspect a compromised device or account belonging to the affected person. Another member points to vulnerabilities in Monta reported by the U.S. agency CISA as a likely cause; the affected person himself criticizes the fact that after an initial authorized payment, further top-ups were possible without reconfirmation. CISA’s warning dated October 1 identifies the platform monta.app as the product; the described vulnerabilities relate to the connection of charging stations, with no specific mention of a charging app.

eCall: Battery replacement for a system fading away with 2G
24 new replies · 15 participants
In the Kona forum, the discussion once again centered on replacing the eCall backup battery, which the manual states should be replaced every three years. One member pointed out that the system uses the 2G network, which will be shut down by 2028; in that case, customers would have to pay to replace it with a non-functional system. Another member explained that Bluelink and eCall are separate systems with their own SIM cards; Hyundai used a 2G SIM for eCall up to the 2026 model year. One member said the backup battery only covers a failure of the 12-volt system for a few minutes, and the system checks it every time it starts and alerts if its power weakens. Only then does this member intend to replace it. Yet another member believes the protected installation is necessary for safety, so that emergency calls can still work even after a severe accident; the only issues are the interval and effort required for replacement.
A KBA technical document was linked for the main review. According to it, an eCall system that no longer functions due to a lack of infrastructure is not considered a defect during the inspection. One member points out that a fault displayed on the screen could still be regarded as a defect and wants to wait to see how this is handled in practice.

Battery problems, big and small
Kona Electric becomes completely non-functional overnight
New topic · 22 replies · 8 participants
The thread starter found his Kona (model year 2023) completely dead in the morning, with even the doors unable to be unlocked. The 12-volt battery still had 6 volts left. He had driven the car the previous day and charged the high-voltage battery. A jump start didn’t help. After removing the battery and charging it with a charger, the car ran normally again, and the error memory was empty. Next, he plans to have a load test done at an independent workshop. The manual specifies a 60-Ah battery, but according to the vehicle’s identification plate, it has a 45 Ah battery; another owner of a 2023 Kona also confirms 45 Ah.
A member said the bridging process works like in a gasoline engine, after which the car should remain in READY mode for about an hour; it advises against using a gasoline engine as a donor. A Kona driver with 170,000 km on the odometer cited a possibly open door or trunk lid as a cause, which prevents the control unit from entering standby mode; he considers a new battery unnecessary after just one incident. Another member recommends replacing the battery every two years or so.

IONIQ 5 reports battery discharge as soon as the cable is connected
New topic · 10 replies · 4 participants
A driver of a 2023 IONIQ-5 needed a new 12-volt battery after it was deeply discharged. This occurred because the car, with its engine off, was connected to a wall charger and did not charge due to insufficient solar power. Since then, when the car is turned on but not in READY mode, the battery icon appears along with the message “Warning: Battery is discharging” shortly after plugging in without any charging current, and the heater fan shuts off. Once power starts flowing, the icon disappears. This behavior did not occur before. One member explained that wall chargers that keep the car in charging readiness mode without actually charging it can drain the 12-volt battery, and advised checking how the wall charger behaves during solar charging. The thread starter then tested it using the included charging brick and observed the same behavior, ruling out the wall charger as the cause. The reason why the car behaves differently now remains unclear.

Nissan Leaf: A failure the workshop cannot replicate
23 new replies · 6 participants
A Leaf driver (model year 2018, about 120,000 km driven, roughly eight years old and thus outside battery warranty) was left stranded on the highway with a “EV System” error message and no power. According to him, diagnostics showed two deeply discharged cells; he estimates the cost at around 2,000 euros for two modules, but Nissan has refused to offer any concession. The workshop was unable to reproduce the error later after clearing the fault memory through a 120 km test drive at speeds of up to 150 km/h. He now intends to sell his Leaf.
A member with similar experience reports that the error only occurred for him after a cold night. Another believes 2,000 euros is reasonable as long as the other modules don’t fail soon. With replacement batteries from China—around 5,000 euros according to one member, around 7,000 euros including import fees and taxes—the installation, durability, and operational approval remain unclear. The same member modified a script for an OVMS module to read cell voltages and error codes; his app then warns of impending cell failures. He claims this has not yet been tested.

V4-Supercharger: Members count four 500-kW stations in Germany
35 new replies · 12 participants
According to a member, Germany now has four Supercharger parks equipped with V4 or 500-kW charging stations. However, not all 36 charging points in Busdorf (Schleswig-Holstein) offer 500 kW; Tesla’s location search shows 415 kW there, likely due to power grid limitations. In Austria, four locations are ready, including Linz with six charging points; Innsbruck is limited to 400 kW.
A member explained that Tesla is upgrading to higher voltages because it has long become a charging provider for all brands—just like with card readers and payment terminals. There was debate over whether higher current levels would result in more losses; the current ratings for different Supercharger generations also remained contentious. The same member considered it a mistake that CCS does not support higher current levels than 500 A.

Fast charging on France’s highways – and in Denmark
New topic · 12 replies · 9 participants
The thread starter drove 1,200 km each way from the Luxembourg border near Carcassonne two weeks ago. According to him, almost all rest stops along the route had large fast-charging parks, some of which were announced as early as 20 km in advance; unattended highway parking lots added another 20 or more charging stations. A member who drove through northern France and Brittany about eight weeks earlier found only one large charging park at roughly eight rest stops, with at most eight charging stations available simultaneously elsewhere. According to one member, quality standards apply on privately operated toll highways, but the situation is worse on toll-free roads; there, large charging parks are more likely to be located next to shopping centers alongside the highway.
From Denmark, a member reported on fast-charging parks between Kolding and Copenhagen spaced 5 to 25 kilometers apart. Another mentioned that Tesla had doubled the number of charging points in Kliplev from 24 to 48, and that the location now offers 96 charging points along with those from other providers. Whether and why Germany lags behind in these rest areas remains debated: one member believes the charging options at German rest stops are sufficient; others cited bureaucracy, the role of Tank & Rast facilities, legal disputes over allocation rights, as well as insufficient space at commercially operated rest areas.

Vienna: Parking fine after interrupted charging process
New topic · 8 replies · 6 participants
The reason was a report from the newspaper “Heute” cited by the thread starter: After a connection issue, charging processes stopped in Vienna, and drivers received parking fines. According to the quote, affected individuals can file an appeal with MA 67; Wien Energie confirms the outage there, and the fine will be waived. A member explains the rules: Parking is prohibited at the chargers except during charging, and after charging ends, one must stay for 15 minutes before the LED ring turns red. They call for more tolerance from the operator in case of outages. A Vienna member who charges frequently at these AC chargers without their own charging facility has never experienced an interruption and considers the system good.

Electric truck drivers: GB/T charging in Georgia
30 new replies · 14 participants
The electric trucker continues his world tour with his electric tractor-trailer equipped with a living cabin. One member summarizes the latest video: The appointments for Mercedes have been completed; due to a fixed entry date for Azerbaijan and a temporary visa for Turkmenistan, the journey is progressing quickly through Georgia. There, according to two members, he charged using an adapter at a GB/T socket, for testing purposes as the station also had a CCS plug. Per one member, this expedition vehicle weighing around 16.5 tons can travel an average of about 950 kilometers per charge; so far, there have been five charging stops.
The members were divided on the entertainment value. Several found the earlier videos more engaging, while one described the trip as “overorganized.” Others argued that many people underestimate charging options outside Germany, and the trip shows exactly that. The crossing of the Caspian Sea is highly anticipated.
