Winter is the “renewal test period” for new energy vehicles — low temperatures can reduce battery activity, air-conditioning heat can add to electricity consumption, and many owners have experienced “show-and-run” “lower charge”. In fact, with good maintenance and power-saving skills, we can significantly ease our flight anxiety
Core: battery maintenance is the “saving foundation”
Battery maintenance during the winter period can directly reduce continuous wear and tear due to cold temperatures and power shortages。
Priority “preheating” reuse vehicles
Battery activity is poor at low temperatures, and driving directly makes the voyage “fast off”. It is recommended that the vehicle be remotely activated (ten-15 minutes in advance) by mobile phone app to preheat batteries and air conditioners:
- battery preheating increases discharge efficiency and renews closer to reality
- an air conditioner pre-heat, free of high power and indirectly saves electricity。
2. Avoid long periods of cooling
To reduce the “frozen” of batteries by stopping in the garage, indoor parking or covering their bodies with their coats (especially in battery positions) to the extent possible, and to keep the vehicles in the open for several days without occasional preheating for 10 minutes to protect the battery's life。
3. Do not wait for “no charge”
Batteries are more difficult to fill during the winter when they are out of power and can accelerate ageing. It is recommended that batteries be maintained between 20 and 80%:
- daily commuting: around 30 per cent is charged, avoiding less than 20 per cent
- long-distance travel: pre-filled, mid-charged, as far as possible, with a “cell preheating” charger (partly supported by a fast charger)。
Key: 30 per cent power savings from air-conditioning matching
The “large households” that consume electricity during the winter are air-conditioning heaters, which are more expensive to cool than summer (especially the ptc-type) and have learned to save much。
Optical heat (thermal pump > ptc)
- if the vehicle has a “heat pump air conditioner”: direct use! It produces the heat by absorbing ambient heat, more than 50 per cent more than the ptc, suitable for areas above -10°c
- if only “ptc” is made: do not open “maximum heat + maximum wind speed” and the temperature is moved to 22-24°c, the wind speed is set at 2-3 (just enough)。
Replace car-wide air conditioning with “local heating”
Air-conditioning heat is heating the car, while seat heating, steering wheel heating is “local heating”, with less electricity consumption:
- a seat to heat (to mid-temperature) + steering wheel to heat, air conditioning to lower slots (e. G. 20°c), warm and power-saving
- when there's no one in the back, turn off the rear air conditioning and avoid waste。
3. Reduced window opening/frequency switch air conditioning
The opening of windows allows the cold air to enter, air conditioning needs to reverse heat and increase electricity consumption; in case of a mist in the vehicle, use the "front wind defusing fog +ac key" (ac key capable of rapid de-wetting), so that the maximum defusing fog is not kept open and the fog is returned to normal mode in a timely manner。
Details: driving habits affect 10-20 per cent renewal
The same car, driven by different people, has more than 100 km of continuity in winter, and smooth driving is key。
Commencement/acceleration of “slower”
Accelerator speed will allow the electric power to work instantaneously with a surge in power consumption. (b) light-stroke the electrical doors at the start, maintain "linear" at acceleration, and avoid hysteria
Maintaining “economic speed” of driving
(a) slower winter speeds: 40-60 km/h in urban areas and 80-100 km/h at high speed (more than 110 km/h, wind resistance increases and the continuation of the voyage is significantly reduced)
Use less brakes and more kinetic energy recovery
Moving kinetic energy recovery to “middle” (e. G., “strength recovery”), vehicles slow down and recover electrical power when the power doors are released, reducing the frequency of brakes, which is equivalent to “reverse power savings”。
Iv. Basic: vehicular inspection to reduce additional electricity consumption
In the winter, minor vehicle failures will also increase electricity consumption and advance inspections will avoid “hidden wear and tear”。
Tyres: don't be too low on the tires
- the winter tire pressure is slightly higher than the summer (reference vehicle manual, usually 0. 2 bar above the standard value), which increases rolling resistance and leads to increased electricity consumption
- examination of the depth of the fetal stripes (below 1. 6 mm for replacement), which reduce the distance of the vehicle's slide and reduce the efficiency of kinetic energy recovery。
Clean-up of snow/ice shells
Uncleaned snow on the roof and doors increases body weight and wind resistance; ice shells on glass are watered with hot water (fragile), ice removal with ice shovels + warm winds, avoiding long periods of high power de-icing。
Emergency: the three respects can be “emergency” in a direct inspection
If you don't know if you're driving, don't panic
Turning off all “non-essential power”
Switch off chairs for heating, steering wheel heating, car-borne acoustics, atmosphere lights, air conditioning to “ventilation mode” (only winding without heat) and retaining only dashboards and lights。
2. Access to “open sections” to avoid traffic congestion
In case of traffic jamming, vehicles are frequently activated, electric machines are repeatedly operating at high power, consuming 20 per cent more electricity than moving at even speed; if navigation has a “scrambling out” route, preference is given (even if one turns around, total electricity consumption may be less)。
“don't wait until full” when charged
It takes 30 to 40 minutes for batteries to be filled from 20 to 80 per cent during the winter season, while 80 to 100 per cent enters the “slow-filling phase” and takes more than one hour, and 80 per cent is enough if you are in a hurry。
Summary
In winter, new energy vehicles are driven, with the core being “battery protection + electricity reduction without use”: pre-heat batteries, air conditioning, smooth driving, and basic inspections will make the voyage more “freezing-resistant”. As long as you get used to driving in the winter, the new energy car can be used to saving money
