For office workers who ride electric vehicles every day, maybe they should learn more about how to choose and love electric vehicles. So today I'd like to talk about some common sense of electric vehicles, so that your electric vehicles can run further.
How to choose and maintain electric bicycle?
Battery maintenance
As a means of transportation, electric vehicles have become popular. It is found that the battery capacity of electric vehicles in winter is much smaller than that in summer, or it becomes difficult to charge or even start. In fact, many of this is due to consumers neglect the maintenance of batteries in winter. The reporter visited several electric vehicle repair shops in the capital to understand the maintenance of electric vehicle batteries.
The best working environment temperature of battery is 15 ℃ ~ 40 ℃. Outside this temperature range, the normal operation of the battery will be affected, and the battery life will be shortened. A normal lead-acid battery can guarantee a maximum driving distance of 50 km. Due to the principle of thermal expansion and cold contraction, when the ambient temperature is - 10 ℃, the battery power can not be fully discharged. In winter, the driving distance with full charge is much less than that in summer. Therefore, the maintenance of the battery is very important.
First of all, in terms of charging, every time you go home, regardless of the length of service, you should charge the battery to keep it in a fully charged state. If you occasionally do not fully charge the battery, it will not affect the battery, but often it will not be fully charged. The battery will produce a kind of "memory", which will affect its continuous mileage, and at the same time, it will also lose the service life of the battery. When charging, plug in the battery plug first and then the power plug. After charging, first pull out the power plug and then the battery plug.
Secondly, start the electric vehicle to avoid high current discharge and reduce the number of people driving. When climbing, it is better to push or assist riding manually, otherwise the battery will be damaged greatly. If the vehicle is not used for several weeks in the open air or cold storage, the battery should be removed and stored in a relatively warm room to prevent the battery from icing damage. Moreover, when the temperature is too low, the use time of electric vehicle should be shortened as far as possible, and charging should be carried out in time. If you do not plan to use the battery car in winter, the battery should not be recharged until the next year. Instead, the battery should be charged once every other month to ensure the storage capacity of lead-acid battery and avoid acid overflow damaging the battery. Maintenance personnel said that battery maintenance should remember to frequently charge, more assistance.
After half a year's use, it's better to do a battery maintenance at the maintenance point, properly supplement the electrolyte of the battery, adjust the specific gravity of the electrolyte, and check its power storage, maintain the specific gravity of the battery electrolyte, and increase the charging times if necessary. At the same time, it is also important to clean the battery terminals and coat them with special grease to protect them. This can ensure the reliability of the electric vehicle starting and prolong the battery life.
What you don't know about the impact of "brakes" and "tires" on range
Compared with "drum brake", disc brake is popular among many consumers due to its fast braking. But maybe you don't know, because the disc brake has more friction during braking, the disc brake device can reduce the range by 5 km under the same other configuration of the vehicle.
Therefore, suitable for dada should be "front wheel drum brake, rear wheel disc brake", which can not only improve safety, but also take into account the range, with the highest cost performance. In addition, the tire should not be too wide. The wider tire has greater friction resistance with the road surface, which will reduce the driving mileage.
Power saving tips in operating habits
Driving speed should not be too fast, because the electric vehicle to the maximum speed of the consumption of electricity is very amazing, speed double, power consumption to be fast 3 to 5 times!
High power consumption means that the whole driving distance of the car is short. At a lower speed and uniform speed, it is not only longer driving distance, but also an effective way to protect the battery.
Special attention: when the battery is running out, if you continue driving, it will cause the greatest damage to the battery, which is very easy to cause irreversible damage to the battery of the electric vehicle. If the battery is out of power, quickly find a place to charge, and do not use the last power forcibly.
Too far away, Qianlima also wants to rest. No matter how good the electric car is, it may need to be checked and nursed after being used for too long.
Tram fire prevention knowledge
The circuit plug-in points of electric bicycles should be checked frequently to prevent the contact points from being ignited and heated due to loose contact, and to avoid short-circuit and series current accidents caused by aging and wear of lines. In the process of normal use of electric vehicles, professional maintenance organizations or personnel should be selected. Do not dismantle the electrical protection device without authorization, so as to ensure that the electrical circuit and protection device are in good condition and effective. The battery of electric bicycle will run out of combustible gas when charging. Therefore, charging must not be carried out in a narrow and sealed environment. It should be carried out outdoors as far as possible, or the battery should be removed for separate charging. When charging, the appropriate circuit should be selected, the line laying should be fixed and installed, and the short circuit and leakage protection device should be installed.
Electric vehicle charging must be far away from flammable materials. The charging time is too long. If the charging time is too long, the overheated charger will easily lead to fire. When charging, the charging should be carried out according to the instructions, and the charging time should not exceed 10 hours in principle. When charging, the charger should be placed in a place where it is easy to dissipate heat; if the battery quality of the electric bicycle is poor or used for a long time, the temperature of the charger is likely to be very high, causing a fire, so charging at night during sleep time should not be taken lightly.
In the process of starting and climbing, the electric bicycle should step on the foot to prevent excessive starting current and overload of parts for a long time, which may cause overheating damage of motor coil, circuit, battery and governor, and even lead to disasters. Try to avoid driving on rainy days and waterlogged roads to prevent water from entering the motor and short-circuit fire when charging.
In addition, when buying electric vehicles, lithium batteries should be the first choice. It has large capacity, less self consumption and less pollution. Secondly, lead-acid dry battery has good sealing performance and is not easy to leak electrolyte. Pollution, corrosion and damage caused by electrolyte leakage must be prevented. When buying electric vehicles, you should read the product manual clearly and operate according to the instructions, and choose the battery matching with the electric vehicle, charger, motor model and specification.
