Frequently Asked Questions
Which vehicles is the HIMS charger compatible with?+
Compatible with all electric and plug-in hybrid vehicles under the Type 2 (Mennekes) standard. Volkswagen, BMW, Mercedes-Benz, Renault, Hyundai, Tesla, TOGG and more.
What do I need for installation?+
An on-site survey and design are required for installing an electric vehicle charger. Our customer representative will contact you to schedule the survey.
How long is the warranty period?+
All HIMS chargers come with a 2-year warranty, providing full protection against manufacturing defects.
How do I use the mobile app?+
Connect to the device via Wi-Fi or Bluetooth to start/stop charging, schedule sessions, and view energy tracking and usage history.
What does IP65 protection rating mean?+
IP65 means the device is fully protected against dust and water jets. Suitable for outdoor use.
How do I apply for a wholesale/dealership account?+
For wholesale and dealership applications, you can email info@himstech.com or reach us by phone at +90 226 812 93 68.
My car isn't charging, what should I do?+
First make sure the cable is seated firmly, until you hear the second 'click', and that 'Connected' appears on the screen. Note any error code shown on the screen or LED. If charging starts and cuts off shortly after, it's usually due to grounding; have an electrician measure the neutral-to-ground voltage. If the problem persists, contact us with your model, the error code, and a short video.
Which charging station should I buy?+
To make the right choice, we need a few details: your vehicle's make and model, its onboard charging power (OBC: 7.4 kW, 11 kW, or 22 kW), whether your home has a single-phase or three-phase supply, whether you'll use the device at home, in a residential complex, or at a workplace, and whether you need an app, RFID, or reporting. With this information, we'll work out the right model together.
Open the product selection wizardWhat does 22 kW mean, does my car draw exactly that?+
22 kW is the maximum power the device can deliver on three phases at 32 A; you can only get this power if your vehicle's onboard charger (OBC) also supports 22 kW. If your vehicle's OBC limit is 11 kW, it will draw only 11 kW from the same device, and on a single-phase connection power is capped at 7.4 kW. The actual power is determined by your vehicle and your electrical installation, not the device. You can check the exact time and power for your vehicle with our calculator tool.
Calculate charging timeWhy does charging cut off after 10-15 minutes?+
If charging starts and then cuts off shortly after, the problem is usually in the wiring, not the device. First have an electrician measure the voltage between neutral and ground; this value should be approximately 1 V. Try lowering the amperage setting, for example from 16 A to 12-14 A, and try again — if it runs stably, the problem is with the grid or the grounding. If the device were genuinely faulty, charging would most likely not start at all.
The screen shows 380 V, why does the car show 220 V?+
This usually isn't a fault; it happens because your car is charging on a single phase. Some vehicles' sockets lack the second and third phase pins, or the car only supports one or two phases; the device's screen may still show all phase voltages on the line. For an accurate diagnosis, have your vehicle's onboard charger (OBC) power and socket configuration checked. If the issue continues, contact us with your vehicle's make and model.
What does the amperage setting do, and why isn't it drawing full power?+
The amperage setting on the device is an upper limit; the actual current drawn is determined by the car itself. For example, even if you set the device to 32 A, your car may draw only 16 A due to factors such as battery condition or temperature; on most models, the screen shows your setting (32 A), not the current the car is actually drawing. This behavior isn't a device fault — it's the car's own strategy.
Why does charging slow down after 90 percent?+
The slowdown after 90 percent doesn't come from the device; it comes from the car's own battery management system — to protect the battery, the car voluntarily reduces the current it draws at higher charge levels. Some vehicles also have a setting that stops charging completely at 80 percent; this is a different behavior and can be changed to 100 percent from the car's menu (Energy/Charging). Neither behavior is a device fault — both are the car's own charging strategy.
How many meters should the charging cable be?+
HIMS Type 2 charging cables come in different length options, up to 3, 5, 8, 10, 15, and 20 meters. To choose the right length, simply measure the distance between your parking spot and the charging device and allow a few extra meters. The cable should not be extended by joining sections end to end; if you need more length, choose a longer cable option instead. Rather than forcing a cable that's too short, work with your dealer to determine the length that suits your distance.
Should I get a socketed model or one with a built-in cable?+
With socketed models, you choose the cable separately and can change it later, which gives flexibility if you need a different vehicle connector or cable length. With integrated-cable models, the cable is fixed to the device, offering a single-piece, simple experience. This choice is independent of whether the unit is portable or wall-mounted: both groups include socketed and integrated-cable models, so let's work out which one suits your needs together.
What is OCPP, do I need it?+
OCPP is the communication protocol that lets a charging device talk to management software or a charging network platform; it enables the device to be managed and reported on remotely. For a customer using the device on their own at home, it usually isn't necessary — the device's own mobile app is enough. OCPP becomes important in residential complexes, workplaces, parking lots, or shared-use scenarios.
Is grounding required, and why is it so important?+
Yes, proper grounding is one of the most critical factors in AC charging. Grounding taken from a weak or shared line can trip the device's protection, cause the car to report an error, or interrupt charging. An electrician should measure the voltage between neutral and ground; this value should be approximately 1 V. If a different brand's device also errors out on the same outlet, the problem lies in the wiring, not the device.
What is V2L, and what is it for?+
V2L (Vehicle-to-Load) is a feature that lets you power electronic devices from a compatible vehicle's battery through an adapter. The HIMS V2L adapter plugs into the car's charging socket and provides a standard outlet (Schuko, approximately 220 V) at its output. It's a practical solution for camping, outdoor events, or emergency power needs. The adapter is available in single-outlet or three-outlet options.
