How to properly store Xiaomi electric scooter in winter

The onset of the cold season puts personal electric vehicle owners on the verge of preserving their vehicles until spring. Low temperatures pose a serious threat to lithium-ion batteries, rubber tires and electronic components of the controller. Xiaomi Mi Electric Scooter, one of the most popular devices in its class, requires special attention to temperature.

Incorrect wintering can lead to irreversible degradation of battery capacity or cracking of materials. In this article, we will discuss the physical processes that occur inside the device in the cold, and draw up a step-by-step plan of action, you will learn why you can not leave a scooter on an unheated balcony and how often you need to recharge the battery during idle time.

Compliance with simple rules will allow you to avoid expensive repairs and maintain the driving performance of your vehicle. We will consider the nuances of preparation, optimal environmental conditions and typical mistakes that users make when trying to save space in the apartment.

Effect of low temperatures on scooter components

The main enemy of any electronics and batteries is not so much the cold itself, as the sharp temperature changes and condensate. Lithium-ion batteries installed in the deck of the scooter, at temperatures below zero, dramatically reduce their return. If you try to charge a frozen battery, irreversible chemical reactions can begin inside, leading to bloating.

Rubber tires tan and lose elasticity in the cold, which increases the risk of microcracks, especially if the scooter is suspended under its own weight. The plastic elements of the housing and the lids of the charging ports also become brittle. Mechanical impact on refrigerated plastic can lead to chipping even with a minor impact.

Electronics, including the BMS (battery management system) and the engine controller, are also sensitive to humidity. When you put a cold device in a warm room, the boards produce condensation. Short circuits on the first switch on after such a wintering are a common cause of failure of the controller.

⚠️ Warning: Never connect a charger to a scooter that has just been introduced from the cold. Let it warm up to room temperature when turned off at least 4-6 hours.

It's important to understand the difference between storage and operation: If the battery is heating itself by the discharge current, it cools to ambient temperature when it's at rest, which is why the temperature range of storage is critical for the longevity of the device.

Optimal environmental conditions for wintering

The ideal place to store a Xiaomi electric scooter is a dry, heated room with a constant temperature of +5 to +25 degrees Celsius. A garage without heating, a shed or an uninsulated balcony are categorically not suitable for long-term equipment. In such places, the temperature often drops below zero, and the humidity can be critically high.

Humidity is the second biggest risk factor. High concentrations of moisture in the air lead to oxidation of contacts and corrosion of metal parts. Even if the scooter itself is dry, moisture can penetrate the deck through vents or seals. Condensation inside the enclosure kills electronics faster than the cold itself.

The storage area should be protected from direct sunlight, even in winter, UV light negatively affects plastic and rubber parts, making them brittle, and avoid areas near heating appliances where temperatures may locally exceed acceptable limits, causing the batteries to overheat.

If you can't keep the scooter warm, you'll have to use additional thermal insulation, although this is only a temporary measure. In any case, temperature stability is more important than absolute values, but staying above freezing point is mandatory.

Preparation of electric scooter for winter storage

Before you take the vehicle out for the winter, you have to do a lot of preparation, the first step is to clean up all the dirt, dust and reagents, in the winter, you treat the roads with salt, which is an aggressive chemical that causes rapid corrosion of aluminum and steel, and you have to do it carefully, without using high-pressure machines, so you don't drive the water in.

After washing the scooter, you need to dry it thoroughly. Pay special attention to the charging port, brake discs and the area around the engine. Lubricating the moving parts before storing will help prevent acidification. Use special lubricants that are resistant to low temperatures if there is a risk that the device will still cool.

Check the tightening of all bolt joints. During the season, vibrations could weaken the fasteners, and when resting under load (if the scooter is on wheels), this can lead to distortions. The braking system must also be in good condition so that the pads do not stick to the discs during the winter.

The optimal charge level for long-term storage of lithium-ion batteries is 60-70%. Do not leave the battery completely discharged or, conversely, 100% charged. In the first case, a deep discharge below the critical level is possible, in the second case, the degradation of battery chemistry due to high rest voltage.

Rules for charging and maintenance of the battery in winter

The battery is the most expensive and important component of the scooter, and even when it's off, it's a process of self-discharge, and the rate of discharge depends on the temperature: the colder it is, the slower it is, but the risk of damage to the structure of the electrolyte is higher, so you need to keep the battery (or the whole scooter) warm.

During the winter, you need to monitor the charge level. It is recommended to check the charge indicator every 3-4 weeks. If the level has fallen below 50%, the battery needs to be recharged. Deep discharge is dangerous because the controller can block charging, considering the battery is faulty, and it will be difficult to restore it.

⚠️ Warning: Do not store the scooter near open fire sources or heaters. overheating of the battery is higher +45 degrees can cause a fire.

If you keep the scooter disassembled (by disconnecting the battery), make sure the contacts are closed from dust and moisture. Lithium-ion cells are sensitive to short circuit terminals. Cyclical recharging helps keep the chemical activity inside the cells at the desired level.

Comparison of storage options: disassembly or whole?

Owners often wonder if they need to disassemble a scooter for the winter, on the one hand, disassembly saves space, on the other hand, it involves unnecessary manipulation of fasteners and the risk of damaging plumes or tearing threads. For most users, the best option is to store them in assembled form.

However, if the space is critically small, you can disconnect the steering rack, this will reduce the dimensions of the device almost in half. Removing the deck (where the battery is) from the wheels is not recommended without professional skills, as this violates the tightness and requires recalibration of some components.

If you choose to unplug the steering wheel, be sure to mark the bolts and monitor the integrity of the cables in the steering column. Fracture of wires inside the rack is a common problem in sloppy assembly and disassembly. Lay the cables so that they do not stretch.

Common mistakes in the preservation of technology

One of the most common mistakes is to store the scooter in a plastic bag, and the film creates a greenhouse effect and prevents air circulation, and if there is even a drop of moisture left on the metal or plastic, an active corrosion process will begin in the closed bag. Use special breathable cloth covers.

Another mistake is to store it in the cold, just in case, and many people think that if it's turned off, it's not going to be cold. It's a misconception. The electrolyte in the battery can freeze, which will destroy the internal structure of the cells, and you can't restore it, only replace it.

💡

Use silica gel bags (moisture absorbers) by placing them next to a scooter or in a case, which will help reduce local humidity and protect electronics from condensation.

Don't forget the tires. If you're on wheels all winter, check the pressure. You'd better lower the pressure a little bit or hang the device to avoid flat spots on the rubber from long static pressures at one point. Rubber tends to deform when you're down for long periods of time, especially at low temperatures.

It's also a mistake to ignite the cleaning before storage, and the remaining dirt and salt will continue to chemically react with the metal throughout the winter, corroding the coating, and in the spring, you may find that the screws have boiled and the disc is covered in rust.

FAQ: Frequently Asked Questions

💡

The main rule of winter storage is heat, dry and battery power is 60-70%, and these three conditions ensure that the scooter starts the first time in the spring.
