The first thing we have to take into account is that electric wheelchairs are all for the user, and each user's situation is different. From the user's point of view, we must make a comprehensive and detailed assessment based on the individual's limb consciousness condition, basic data such as height and weight, daily needs, usage environment and special surrounding factors, etc., in order to make an effective selection and gradually subtract until we choose a suitable electric wheelchair.
In fact, the conditions for selecting an electric wheelchair and an ordinary wheelchair are basically similar. When selecting the seat back height and seat width, the following selection method can be used: the user sits on the electric wheelchair without hooked knees and can naturally lower the lower legs at a 90° right angle is most appropriate. The appropriate width of the seat surface is the widest position of the hips, plus 1-2cm on each side.
If the user sits, knees slightly high, there will be curled legs, sitting is very uncomfortable, if the selection of the seat surface is narrow, sitting will be more crowded, wide, long-term sedentary will cause secondary injuries such as spinal deformation.
Then also consider the weight of the user, if the weight is light, the use of environmental road flat, brushless motor cost-effective; if the weight is heavy, road conditions are not very good, the need for long-distance travel, it is recommended to choose worm gear motor (brush motor).
The easiest way to test the power of the motor is to climb the test, climbing to test the motor is easy or slightly strained. Try not to choose a small horse-drawn motor, there will be many failure problems later, if the user is more hilly, worm gear motor is recommended.
Electric wheelchair range is also a lot of users concerned about the link, to understand the properties of the battery, and AH capacity, if the commodity description of about 25 km, it is recommended that the budget range of 20 km, because the test environment and the actual use of the environment will be different. For example, the northern winter range are reduced, and the colder hours try not to drive the electric wheelchair out, will cause great and irreversible damage to the battery.
Generally speaking, the battery in AH capacity and range is approx.
- 6AH range 8-10km
- 12AH 15-20km range
- 20AH 30-35km range
- 40AH range of 60-70 km
The battery range is related to the battery quality, the weight of the electric wheelchair, the weight of the rider and the road conditions.
Long-term users of electric wheelchairs may find that the battery range is slowly shortened, and a check reveals that the battery is bulging. Either a full charge on a run on no power, or how to charge is not charged. Do not worry, today will tell you how to properly maintain the battery.
Electric wheelchair in the driving state, the battery itself will be hot, coupled with the hot weather, the temperature of the battery is even up to about 70 ℃, the battery has not yet cooled to the ambient temperature situation, electric wheelchair as soon as it stops charging, will intensify the battery's lack of liquid water loss, reduce the service life of the battery, and intensify the risk of battery charging drum.
It is recommended to stop the electric wheelchair for more than half an hour and wait for the battery to cool sufficiently before charging. If the battery and motor are abnormally hot during the driving process of the electric wheelchair, please go to the professional electric wheelchair maintenance department for testing and repair in time.
The battery will also heat up during the charging process, and if it is charged in direct sunlight, it will also cause the battery to lose water and cause a bulge on the battery. Try to charge the battery in the shade or choose to charge the electric wheelchair in the evening.
Using a mismatched charger to charge the electric wheelchair may result in damage to the charger or damage to the battery. For example, using a charger with a large output current to charge a small battery is very likely to cause the battery to bulge.
It is recommended to go to a professional electric wheelchair after-sales repair store to replace the matching quality brand charger to ensure the quality of charging and extend the life of the battery.
Many electric wheelchair users often charge throughout the night for convenience, charging time often exceeds 12 hours, and sometimes even forget to cut off the power charging time of more than 20 hours, this is bound to cause great damage to the battery. Multiple long-time charging can easily lead to the battery being filled with drums due to overcharging. The general electric wheelchair can be charged for 8 hours using a matching charger.
Try to keep the electric wheelchair battery in a fully charged state before traveling, and according to the actual electric wheelchair range activities, long-distance travel can choose to take public transportation.
Many cities have fast-charging stations. Using fast-charging stations for high-current charging can easily lead to water loss and bulging of the battery, thus affecting the battery life, so try to reduce the number of times you use fast-charging stations for charging.
