Hello, i'm a digital blogger, and i'm here today to share experiences! The electric bicycle has now become a digital walker for the vast majority of households travelling on short distances, with almost one in the household, whether daily commuters, or buying food for children. However, many of the drivers have experienced the same terrible thing: they lost their cliffs after more than a year, could have run for 40 and 50 kilometres, spent 20 miles later, went to the garage to replace a group of bottles with $4,500, and the year-to-year change of batteries was a huge expense。
I know a teacher who has been working on electric cars for more than a decade and who normally receives thousands of car owners, and he personally told me that the vast majority of the bottles that are emptied early are not a matter of the quality of the batteries themselves, but rather a critical operation that is ignored by the owner when he stops, recharging, and continues to cause permanent damage to the polar plates, with the bottle being lost half of its life. Today, as a producer in the field of deep-tilled digital hardware and energy batteries, i have completely dismantled the battery maintenance dryer, which has been understood by the mechanics, with little outreach in the industry, distinguishing between lead acid and lithium power, the two main electric car batteries, and teaching you how to stop and charge the whole thing properly。
Why does your electric car bottle end up in a year? 90% of the car owners step on the pit
Before explaining core parking maintenance techniques, the rationale behind the fast decay of the cylinders is clarified. There are currently two main battery types of publicly available electric vehicles: traditional lead-acid cylinders (priced country standarding), lithium batteries (used in high-end light quantification vehicles), and two batteries, although with different internal structures, cause of damage, which overlaps highly。
(i) core cause of damage to lead-acid cylinders: polar sulphide
Chemical reactions within lead-acid cylinders rely on sulphate electrolyte and lead polar panels to store electricity, with the greatest fear of loss of electrostatics, high-temperature power storage and large current shocks. Many of the vehicles are locked directly on their way home, and the vehicle controllers and dashboards remain in a weak state of power consumption, with prolonged stoppages continuing to empty the remaining batteries and enter the power deficit pattern. In a state of power loss, the electrolytic solution will reveal that lead sulphate crystals are attached to the polar surface, blocking the ion channel, and that subsequent recharges cannot be completely restored, and the battery capacity will be permanently reduced, that is to say, what the owner of the vehicle often calls “no battery”。
(ii) core causes of damage to lithium batteries: core pressure differential, heat decay
Lithium batteries consist of dozens of independent corings, with their own protection panels, but long-term low-pressure stoppages continue to cause overcharges of single-saving cores, imbalances in the core voltage, and the entire group of batteries continue to shrink; at the same time, lithium batteries are less resistant to heat, vehicles are stopped directly after sunbathing, internal temperatures continue to rise, accelerated electrolyte aging, and problems with drum packs and renewed crashes。
(iii) daily hf error count of vehicle owner
1. Direct locking at the end of the cycle, permanent electrostaticization, and continued slow consumption of electricity
2. The exhaustion of electricity is associated with recharge and frequent deep discharge
3. In the summer, when the vehicles are tanned, they are charged immediately after parking
4. Combining different types of chargers with uninterrupted charge throughout the night
For a long period of one month or two, there was no power supply。
These customary superstitions, as well as the perfect original cylinders, cause severe decay during a period of 12 to 18 months and can only be replaced earlier. The “one step more” of the mechanic's mouth is precisely the best way to circumvent the biggest damage point of slow power loss from the source and the least costly and simplest means of battery maintenance。
Ii. Car mechanics do not upload core operations: parking and power outages, simple step-by-step extension of three years of life
This operation does not have any threshold and does not require the purchase of additional spare parts, but takes three more seconds to complete each time you lock the car, in two models。
(i) the self-carrying total power switch type (mainstream new pay country brand)
The vast majority of nationally marked electric vehicles leaving the plant after 2022 are equipped with a total power source air switch on the side side of the battery silo and below the cushion, with some of the models marked as “power outage/master”。
Correct parking process: ride to the destination to close the vehicle's electrical door key to the main power source and concern about cutting off the entire vehicle's power supply and locking the vehicle。
Many car owners buy cars without informing them of the role of the switch and maintain electrical power throughout the day. Even when vehicles are shut down, the controllers, security alarms and power display screens will continue to deplete electricity, with static power consumption of 8 to 12 hours per day and 3 to 5 per cent per day; if they are suspended for three to five days without riding, the remaining power will be found directly at the bottom, directly causing a deficit in electricity sulphide. The main gate was cut off by parking, the entire circuit was completely disconnected, there was no self-discharged wear and tear, and damage to the electric cylinders was avoided from the source。
(ii) old electric car with no total power switch (old lead acid model)
There are two types of operation:
1. Short-distance parking (recycling again within 1 - 2 days): after closing the key, manually removing the plugs connected to the battery and body and separating the power lines
2. Long-term parking (more than three days without a vehicle): the battery is removed directly from the body of the vehicle and stored separately, in a cool and dry place, and is replenished once a month。
(iii) manual details added, distinguishing lead acid from lithium electricity
Lead-acid cylinders: unreversible sulfurization of deficit power, parking and power outages are the most cost-effective means of maintenance, and consistent use can directly prolong the useful life of two to three years
Lithium batteries: a single-saving core overlay will permanently damage the core, long-term power outages will balance the core voltage, reduce the risk of drum packs and slow the continuation of flight decay。
Many owners will question whether the main gate and plugs will be damaged every day. Teacher master provides a clear answer: regular locks and battery plugs are tested thousands of times, and daily operations do not cause poor exposure for two to three years; instead, they are static for a long period of time, and the lines continue to work on micro-electricity, making it easier to speed up the aging of the lines, heat short circuits and safety risks。
Iii. Double the effect of the combination of charge maintenance techniques and parking cuts
It is not enough to stop the power outages, and to maximize the protection of the cylinders in combination with proper charging habits, the following three parts of the generic technique, lead acid exclusives and lithium exclusives, all of which are measured digital storage dry。
(i) guidelines for the universal charging of batteries of all types
1. Do not recharge immediately after riding
The vehicle's mobile batteries continue to discharge, the internal temperature rises, the temperature of the batteries can be higher than 50°c after the summer tan, and the immediate charge increases the heat and triggers thermal damage. Correct practice: parking is cut off for 15-20 minutes, and battery temperatures are fully recharging at constant temperatures。
2. Control of charge duration and prohibition of all night charge
Normal 48v lead-acid cylinders are fully filled with only 6-8 hours, and 60v lithium charge time is kept within 7 hours; when the charger signal is green, the additional charge is cut at a maximum of 1-2 hours. Overcharging occurs over 12 hours in the night, lead-acid cylinders accelerate water loss drums and long-term high pressure panels for lithium batteries accelerate ageing。
3. Recharging environments to keep ventilated and cool
Charges are prohibited in closed buildings, indoors, open-air hots, with priority given to the charging of the sunshields and ventilated car sheds; when charged, no clothing, box-packing batteries and chargers are used to avoid the risk of heat accumulation。
4. Specialized car chargers, prohibition of mixing
The chargeable currents of different voltages, capacity batteries, and cut-off parameters are completely different, and mixing chargers cause a mismatch of chargeable voltages and directly penetrate battery protection panels. When the original charger is damaged, the same-specified product must be purchased according to battery rating parameters, and no cheap choice of three uncharged appliances must be made。
(ii) elements for exclusive maintenance of lead-acid cylinders
1. Optimal charge time: 40 to 50 per cent charge the remaining capacity, without completely exhausting the recharge, once in depth discharge, equivalent to one month's useful life of the lost cylinder
2. Long-term idle storage: full charge once a month, full of post-disable main gate storage, and no more than one month of deficit placement
3. Ride assistive techniques: foot boosting to reduce the sudden electrical outage of electric power and to avoid polar crystal damage。
(iii) points for exclusive maintenance of lithium batteries
1. Lightness and greater durability: lithium batteries have no memory effect, need not be deliberately recharged, with half of the daily power remaining to be replenished, and long-term full-charge storage accelerates the ageing of the core
2. Reduction of full power storage during the high-temperature season: long-term outages during the summer, with electricity at around 60 per cent optimal and no electric storm outages
3. Periodic testing: after one year of use, core pressure differentials can be detected at the maintenance shop, which are overweight and balanced in a timely manner, avoiding damage to single-dimensional cores and dragging whole batteries。
Iv. Specialized answers to common owner questions, avoiding maintenance errors
Question 1: is it necessary to cut the total power supply for only a few hours a day
Answer: very necessary. Vehicle alarms are available on a 24-hour basis, even if only eight hours per day, with daily accumulations continuing to consume electricity, especially in low-temperature conditions during winter, reduced battery capacity per se, and low power consumption is more likely to result in rapid power losses. The daily parking and power cuts could reduce battery decay by more than 60 per cent over the long term。
Question 2: are the electric vehicle alarms still working after cutting the main gate
Response: the sub-car design, some of the vehicle-type anti-piracy units are directly connected to the main battery line, the main gate is broken and the main gate is broken; if there is a fear that the vehicle may be stolen, it may be split into a scenario: short-distance parking for a few hours without breaking the main gate; off-duty and night-time parking takes place for a long period of time, making it necessary to break the battery protection vials, have surveillance in the night sector, have a lower risk of theft and give priority to battery protection。
Question 3: is there any repair that can be repaired by insisting on parking and power cuts
Response: if only slight decay (within 30 per cent of the continuation of the vessel) is maintained, the power outage + charge will slow down the rate of damage and prevent the continuation from continuing to collapse; if the cylinders are already heavily sulfurized and the drums are deformed, the internal polar plate damage is irreversible and only new batteries can be replaced, and the new batteries will be used to maintain this maintenance method for a substantial length of time。
Question 4: how can batteries be kept in the safest place for longer than a month on a long mission
Response: first stop, cut the total power supply; second move, charge 50-60% power; third move, put a cool, dry, 10-25°c environment in storage; when you return from a mission, fill up the electricity and then you ride normally, and let your family help with the power again once a month, without causing any damage to the battery。
V. Additional reminder for safe use of bottles, technology for rational use
As digital publisher, in addition to sharing battery life-long techniques, you must be reminded of the safety norms for the use of electric vehicles to avoid spontaneous combustion:
1. Strictly observe fire-fighting regulations, prohibiting the entry of electric vehicles into buildings, charging of buildings, charging of high-altitude flight lines, and the uniform discharge of off-site special-charging sheds
2. Batteries with shell drums, charging abnormally hot, circuits broken and immediately ceased to be used, sent to a specialized store for overhaul and no further riding
3. Non-self-retrofitting of batteries, increase of battery capacity and installation of high-power light acoustics, which would destroy the original plant's electrical circuit protection design and would easily trigger short circuit fire
Thunderstorms do not charge outdoors in the weather. Rainwater intrusion into the recharge interface creates short circuits and damage to batteries carries the risk of fire。
