Difficulty in Starting and Unstable Operation: Due to poor quality electrode materials and electrolyte, substandard batteries have increased internal resistance and rapidly decreasing discharge voltage. This not only makes it difficult to start equipment, such as motorcycles failing to start, but also causes voltage fluctuations during operation, leading to unstable equipment performance, like frequent restarts of data center servers.

Shortened Lifespan: Poor material quality can lead to incomplete chemical reactions and electrode material shedding, causing the battery capacity to drop quickly and shortening its lifespan. This increases the maintenance cost and downtime of equipment, such as the need for frequent battery replacements in UPS systems.

Safety and Environment

Equipment Damage and Safety Risks: Leakage and expansion issues can cause electrolyte to corrode the metal parts and electronic components of equipment, causing damage. Moreover, the poor quality casing of substandard batteries can easily break, potentially causing short circuits, overheating, and even fires, endangering personnel and property safety.

Environmental Pollution: Substandard batteries are prone to leaking harmful substances, such as lead and acid, during use and disposal, posing a threat to the ecological environment and human health. Discarded substandard batteries can contaminate soil and water sources if not disposed of properly.

Economy

Increased Maintenance Costs: Due to unstable performance, frequent inspections and maintenance are required, and the replacement frequency is high, which significantly increases the maintenance cost of equipment, affecting its economic efficiency and usability.

Do you own a low-speed vehicle, such as an electric bike or electric scooter? If so, you may find that Low-Speed Vehicle Battery life becomes a worrying issue. Fortunately, we have some simple ways to help you maintain and extend the life of your low-speed vehicle battery. Let's find out together!

Avoid overcharging and discharging: When using a low-speed vehicle, try to avoid overcharging and discharging the battery. Overcharging can cause the battery to overheat and lose capacity, while over-discharging can damage the battery's performance. So, when the battery is close to being exhausted, charge it in time to avoid long-term discharge or over-discharge.

Proper charging method: When charging, it is also important to choose the appropriate charging method. Use the charger provided by the original manufacturer or certified charging equipment, and avoid using an inappropriate charger to avoid damage to the battery.

Avoid high and low temperature environments: Batteries are sensitive to temperature, and too high or too low temperatures will have a negative impact on battery life. When storing batteries, choose a dry, ventilated place with a suitable temperature. In extreme weather conditions, try to avoid exposing the battery to overheating or over-cold environments for a long time.

Regular battery maintenance: Check the appearance and connection lines of the battery regularly to ensure that there is no damage or rust. Keep the battery dry and clean to prevent moisture from entering the battery. If you find any problems with the battery, ask a professional to repair or replace it in time.

Reasonable use of low-speed vehicles: The life of the battery of a low-speed vehicle is closely related to the way it is used. Try to avoid overloading and do not drive continuously at high speed for a long time. Reasonable use of low-speed mode and energy-saving mode can reduce the pressure on the battery and extend the battery life.

Fully charge and discharge: Try to keep the battery in the medium power range. Too frequent partial discharge and charging will cause additional pressure on the battery. So, don't always wait until the battery power is very low before charging, and don't always use the battery immediately after it is fully charged. Moderate charging and discharging is beneficial to extend the battery life.

By paying attention to the above tips, you can extend the life of the battery of a low-speed vehicle. Remember, maintaining the good condition of the battery is essential to ensure the reliability and long-term use of low-speed vehicles. I hope these tips can help you and enjoy longer low-speed travel!

With the increasing awareness of environmental protection and the demand for renewable energy, low-speed vehicle batteries have become a highly sought-after energy solution. Compared with traditional automotive batteries, low-speed vehicle batteries are very different in design and purpose.

First, low-speed vehicle batteries usually use lithium battery technology, while traditional automotive batteries usually use lead-acid battery technology. Lithium batteries generate current by the migration of lithium ions between positive and negative electrodes, while lead-acid batteries generate current through the chemical reaction between lead and sulfuric acid. Lithium batteries have significant advantages in energy density, charge and discharge efficiency, and life, so they are widely used in low-speed vehicles.

Second, low-speed vehicle batteries usually have a smaller capacity and lower voltage. Low-speed vehicles are mainly used for short-distance travel and urban driving, so the requirements for cruising range and maximum speed are relatively low. The design of low-speed vehicle batteries pays more attention to economy and practicality, using relatively small capacity battery packs to reduce costs and improve energy utilization.

In addition, low-speed vehicle batteries usually use a simpler management system. Traditional automotive batteries require complex battery management systems to monitor battery status, balance charge, and prevent overcharging and over-discharging. The management requirements for low-speed vehicle batteries are relatively low, and generally only simple protection modules are needed to ensure the safe operation of the battery.

In addition, the cost of low-speed vehicle batteries is relatively low. Traditional car batteries are expensive because they need to meet the requirements of high energy density and large capacity. Low-speed vehicle batteries have a smaller capacity and use relatively cheap lithium battery technology, making their cost more controllable and economical.

In summary, low-speed vehicle batteries are an energy solution designed specifically for urban travel and short-distance driving. Compared with traditional car batteries, they use lithium battery technology, simple design, low cost, and focus on economy and practicality. As the demand for sustainable travel increases, low-speed vehicle batteries are expected to be more widely used in the future.

How do half-cut solar cells work?

Half-cut solar cell technology increases the energy output of solar panels by reducing the size of the cells, so more can fit on the panel. The panel is then split in half so the top operates independently of the bottom, which means more energy is created – even if one half is shaded.

That’s the general overview – below, we break the process down.

Traditional monocrystalline solar panels usually have 60 to 72 solar cells, so when those cells are cut in half, the number of cells increases. Half-cut panels have 120 to 144 cells and are usually made with PERC technology, which offers higher module efficiency.

The cells are cut in half, very delicately, with a laser. By cutting these cells in half, the current within the cells is also halved, which essentially means that resistive losses from traveling energy via current are reduced, which, in turn, equals better performance.

Since the solar cells are cut in half, and are thereby reduced in size, they have more cells on the panel than traditional panels do. The panel itself is then split in half so that the top and bottom portions operate as two separate panels – generating energy even if one half is shaded.

The key to half-cut cell design is a different method of “series wiring” for the panel, or the way the solar cells are wired together and pass electricity through a bypass diode within a panel. The bypass diode, indicated by the red line in the images below, carries the electricity that the cells generate to the junction box.

In a traditional panel, when one cell is shaded or faulty and does not process energy, the entire row that is within the series wiring will stop producing power.

For example, let’s take a look at the traditional 3-string series wiring method:

With the traditional full cell string series wiring, shown above, if a solar cell in Row 1 does not have ample sunlight, every cell within that series will not produce energy. This knocks out a third of the panel.

A half-cut, 6-string solar panel works a bit differently:

If a solar cell in Row 1 is shaded, the cells within that row (and that row only) will stop producing power. Row 4 will continue to produce power, generating more energy than a traditional series wiring because only one-sixth of the panel has stopped producing power, instead of one-third.

You can also see that the panel itself is split in half, so there are 6 total cell groups instead of 3. The bypass diode connects in the middle of the panel, instead of on one side like the traditional wiring above.

What are the advantages of half-cut cells?

The advantages of half-cut cell panels are numerous.

They improve the power output and performance of solar modules because they offer a higher shade tolerance due to their unique wiring system. This means that if your home has some trees that cast shade onto your roof at certain times during the day, your entire solar panel will not be unusable, like it would with a traditional solar panel.

Another benefit is the fact that they usually offer a higher wattage than traditional panels, meaning they produce more power per square foot.

Additionally, the effects of hot spots are less severe on your solar panels with half-cut cells. Hot spots are the shifting of excess heat on a panel, say from a very hot part to the shaded, cooler section. With a half-cut cell, hot spots will not be as damaging because there are more cells to spread the excess heat to.

Half-cut cells also reduce power loss suffered by traditional panels by reducing internal resistance. Internal series resistance occurs just by the nature of energy traveling through the panel via electric current. But because solar cells are cut in half, there is less current generated from each cell, meaning less resistive losses.

Amid constant iteration in high-efficiency solar cell technology, domestic businesses have exceeded 23% in the efficiency of mass production at new PERC production lines in 2021, and managed to develop ceilings at an efficiency of almost 24%, which further solidifies the determination of domestic businesses in establishing additional production lines for the N-type solar cell.

In the race to develop the most efficient type of solar panels, manufacturers have developed bifacial solar panels. This type of panel has solar cells on both sides which allows the technology to capture more sunlight leading to greater solar cell efficiency compared to traditional solar arrays.

How Do Bifacial Solar Panels Work?
Lets first dig deep into how bifacial solar panels function. The top and bottom solar cells on a bifacial solar array function differently. The top solar cells function like a conventional solar panel array. They face the sun, so they capture incident sun rays directly, absorbing only certain wavelengths.

On the other hand, the bottom solar cells absorb light that is reflected off the ground. Since white or light colors reflect better than dark colors, painting a white or silver surface on the roof or driveway under the panels is encouraged. According to a study by Burns & McDonnell, white surfaces reflect more than 80% of this light while grass only reflects 23%.

How Is Bifacial Solar Panels Installed to Increase Efficiency?
To understand the difference, let’s first uncover how a monofacial solar array is set up. A monofacial solar panel system, or a group of one-sided solar panels, are placed in racks parallel to a surface such as a rooftop. Unlike single-sided panels, bifacial solar panels are installed on a tilt because they produce more energy when they are angled off of the roof or ground at varying degrees.

Below are three benefits of the titled installment of the bifacial solar array.

1. More sunlight to absorb
In these types of titled installations, there is a great amount of reflection. Because sunlight bounces off of all objects reflectively at many different angles, bifacial solar panels are able to capture more of it.

2. Productive on cloudy days
Because of the point above, bifacials can be productive on cloudy days while monofacial solar cells are at a greater disadvantage when there isn’t direct sunlight. Also, bifacials are less susceptible to weather damage because they are more durable. According to the Solar Magazine, because they are more durable than conventional solar panel systems, warranties for bifacial solar panels are typically 5+ years longer (that is, 30+ years versus 20–25 years).

3. Two energy peaks a day
A titled installation can also produce two energy peaks throughout the day based on their placement. For example, half of the bifacials in an array can be tilted toward the east to capture sunrise and morning rays. The second half can then be tilted to the west to soak up afternoon intensity and sunset rays.

Another installation that can achieve this is a vertical installation. During each peak, the reflection of sunlight on the other side of the solar panels will also contribute to energy production.

How Much More Efficient is a Bifacial Solar Array?
When we say efficiency, we are referring to how a solar cell takes the amount of solar energy it received and converts it into electrical energy. Although bifacials produce more electricity than monofacial panels, it definitely isn’t double the efficiency although solar panel manufacturers are working to make that happen in the future. Bifacials can increase energy efficiency by 11% compared to a conventional solar panel system, according to our study. And with a solar tracking system that tilts solar cells continuously toward the sun, the bifacial solar cell efficiency can be as high as 27%.
