How does lead-acid battery affect the performance and use of four wheels power remote electronic wheelchair? ​

​
As a chemical power source, the working principle of lead-acid battery is based on the chemical reaction between lead and its oxide and sulfuric acid solution. The battery is mainly composed of positive and negative plates, separators, electrolytes, etc. The active material on the positive plate is lead dioxide, the active material on the negative plate is sponge-like lead, and the electrolyte is sulfuric acid aqueous solution. During the charging process, the electrical energy causes the chemical reaction to proceed in reverse, converting the electrical energy into chemical energy for storage; while during discharge, the chemical reaction occurs in the forward direction, and the chemical energy is converted into electrical energy to power the motor, controller and other components of the four-wheel power remote electronic wheelchair. ​
From a cost perspective, lead-acid batteries have significant advantages. The raw materials required to manufacture lead-acid batteries, such as lead and sulfuric acid, are in sufficient supply in the market, and the refining and processing technology is mature, which makes the production cost of lead-acid batteries relatively low. Reflected in the price of four-wheel power remote electronic wheelchairs, wheelchairs equipped with lead-acid batteries are often more affordable, allowing more consumers in need to afford them. For users with limited budgets, this is undoubtedly an attractive option, allowing them to enjoy the convenience of electric wheelchairs at a lower cost. ​
In terms of safety, lead-acid batteries also perform well. After long-term development and improvement, the structural design and manufacturing process of lead-acid batteries have been continuously optimized. Its shell is usually made of sturdy engineering plastic material, which has good sealing and impact resistance, and can effectively prevent electrolyte leakage and external physical damage. Under normal use conditions, lead-acid batteries are not prone to explosions, fires and other dangerous situations. Even when subjected to a certain degree of collision or extrusion, its structural design can guarantee the safety of the battery to a certain extent, providing reliable protection for users. ​
The high reliability of lead-acid batteries should not be ignored. It can work normally in a wide temperature range. Whether it is cold winter or hot summer, as long as it is within a reasonable temperature range, lead-acid batteries can output electrical energy stably. In addition, lead-acid batteries have relatively low requirements for the charging environment, do not require complex charging equipment and special charging conditions, and ordinary household power can meet its charging needs. This high reliability enables the four-wheeled electric remote control electric wheelchair to operate stably in various daily use scenarios, reducing failures and inconveniences caused by battery problems.​
However, lead-acid batteries also have obvious shortcomings. Their energy density is relatively low, which means that lead-acid batteries of the same volume and weight store less electrical energy than some new batteries. On a four-wheeled electric remote-controlled electric wheelchair, this results in limited vehicle range. Although increasing battery capacity can improve range to a certain extent, this will increase the weight and volume of the battery, affecting the maneuverability and portability of the wheelchair. ​
Moreover, the cycle life of lead-acid batteries is relatively short. As the number of charge and discharge cycles increases, the active substances inside the battery will gradually be consumed, and the plates will have problems such as sulfidation and corrosion, resulting in a continuous decrease in battery capacity and a gradual decline in performance. When the battery capacity drops to a certain level, it cannot meet the normal use requirements of the four-wheeled electric remote-controlled electric wheelchair and needs to be replaced. This not only increases the cost of use, but also frequently replaces the battery, which brings many inconveniences to users. ​
In terms of weight, lead-acid batteries are heavy due to their own chemical composition and structural characteristics. The presence of a large amount of lead material and electrolyte makes the entire battery pack bulky. For a four-wheeled electric remote control electronic wheelchair, an overweight battery will increase the overall weight of the vehicle, affecting its acceleration performance and maneuverability. When carrying or moving the wheelchair, a heavier battery will also bring a greater burden to the user or caregiver. ​
In actual use, the performance of lead-acid batteries will also be affected by many factors. Temperature is one of the important factors. When the temperature is low, the chemical reaction rate inside the battery slows down, the fluidity of the electrolyte deteriorates, resulting in a decrease in the discharge capacity of the battery, and the mileage of the four wheels power remote electronic wheelchair will be significantly shortened; in a high temperature environment, the self-discharge rate of the battery is accelerated, and the evaporation of the electrolyte is intensified, which will accelerate the aging and damage of the battery. In addition, the charging and discharging method also has an important impact on the battery performance. Unreasonable charging and discharging behaviors such as over-discharging, charging time that is too long or too short, will accelerate the decline of battery performance. ​
In order to ensure the good performance and service life of lead-acid batteries in four-wheeled electric remote control electric wheelchairs, correct maintenance is essential. Regularly checking the electrolyte level of the battery is an important task. When the level is lower than the standard line, distilled water or special lead-acid battery supplementary fluid needs to be added to ensure that the electrolyte can fully infiltrate the plates and maintain normal chemical reactions. During the charging process, use a suitable charger and charge strictly according to the specified charging time and charging voltage to avoid overcharging or undercharging. At the same time, try to avoid using the wheelchair when the battery power is too low to prevent excessive discharge. ​
Improvement and optimization technologies for lead-acid batteries are also emerging. , which improves the energy density and cycle life of the battery; some batteries have been innovated in structural design, reducing the weight of the battery and improving the overall performance. The application of these technologies has continuously improved the performance of four-wheeled electric remote-controlled electric wheelchairs equipped with lead-acid batteries, bringing users a better experience. ​
Although lead-acid batteries have certain limitations, they still occupy an important position in the field of four-wheeled electric remote-controlled electric wheelchairs due to their advantages such as high safety and strong reliability. Through proper use and maintenance, as well as continuous technological improvements, lead-acid batteries can continue to provide stable power support for four-wheel electric remote-controlled electric wheelchairs, helping people with limited mobility to travel more conveniently and freely.
