With the development of the electric two-wheeler industry, the market demand for swappable battery is gradually increasing. Some well-known companies, including Tycorun, have invested heavily in research and development funds to explore new technologies and better products.
At the same time, research and development of more efficient charging and battery swapping technologies to help the development of environmentally friendly transportation. It is expected that in the near future, swappable battery will become one of the more convenient, economical and environmentally friendly options.
1. What is a swappable battery
Swappable battery refers to a detachable power battery, which is suitable for new energy vehicles such as electric vehicles. The battery can be swapped out at a tram charging station and takes only a few minutes to complete.
Equivalent to an alternative to fast charging and charging. The development of this technology makes the use of electric vehicles more convenient and avoids the problem of waiting times for charging.
2. The characteristics of swappable battery
Swappable battery refers to batteries that can be easily replaced, and are usually used in car-sharing, bicycle-sharing and other fields. There are currently two types of swappable batteries: lead-acid batteries and lithium-ion batteries.
Among them, lithium battery is currently the mainstream swappable battery, which is popular because of large capacity, fast charging speed, long service life, light weight, and small size.
- Capacity
The battery capacity is generally about 100Wh. In the car-sharing industry, it is usually around 150Wh to meet the demand for a higher range.
- Charging speed
The charging speed is related to the type of battery and the depth of discharge. In general, lead-acid batteries charge more slowly, while lithium-ion batteries charge faster. In particular, batteries with ternary materials charge faster.
- Security
Battery safety is very important because it involves the personal safety of the user. Lead-acid batteries have been phased out due to their easy leakage and explosive properties.
As a safer battery, lithium-ion batteries adopt a new battery management system and special circuit protection technology, which can effectively reduce the safety risks of the battery in the process of charging and discharging.
3. What are the advantages of swappable battery
There are some significant advantages to swappable battery. First of all, the charging time is short, which solves the problem that ordinary charging takes several hours. Secondly, this kind of battery can be updated and replaced at the end of its battery life, saving the cost and time of battery renewal.
However, there are also some disadvantages to swappable, such as higher cost and more time spent replacing the battery. In addition, due to the mass and weight of the battery, the vehicle may need to stop and insert the battery stably.
4. What is the voltage of swappable battery
The voltage of the swappable can be 48V, 60V or 72V. The voltage of an electric motorcycle battery depends on the number of batteries. The standard voltage for a single battery is 12V(12 volt 200ah lithium battery), so if 4 batteries are installed, the voltage is 48V.
This classification is based on the voltages of the battery, which is the voltage of the battery, which is an important indicator of the performance of an electric motorcycle.
The higher the volt, the more range the EV will usually have, but it also requires a more powerful motor and controller to match. In addition to volts, the battery's amperage (capacity) is also a key parameter, which determines the battery's power storage capacity.
Common battery amperages include 12Ah(12v 100ah lithium ion batteries), 20Ah, 32Ah, 38Ah, etc. Different combinations of amperage and voltages, such as 48V12Ah or 60V20Ah, will directly affect the range and performance of electric vehicles. When replacing an battery, you must ensure that the voltage of the new battery is the same as that of the original battery to avoid incompatibility problems.
For example, if the primary battery is 48V, then the 48V battery should also be selected when replacing it, rather than the 60V or other voltage battery, as this requires the corresponding charger to match. Incorrect voltage matching may result in damage to the battery or failure of the vehicle to function properly.
5. Can I charge the battery of battery swapping station
The answer is yes, but it depends on the type of swappable battery and how it is charged. At present, the common battery swapping station batteries on the market include lead-acid batteries and lithium-ion batteries, among which lithium-ion batteries are the most widely used. Here we take lithium-ion batteries as an example.
There are two ways to charge lithium-ion batteries, one is DC charging and the other is AC charging. If you want to charge the battery of the battery swapping station by yourself, you need to understand the charging mode and the parameters of the charger first, so as to avoid damage to the battery due to the mismatch of the charger.
For non-professionals, if you don't have the relevant battery charging experience and equipment, it is best to choose to send the battery directly to a professional charging station or repair station for charging and repair.
6. Precautions before charging the battery of battery swapping station
- Charger parameters match
Choose a charger that matches the battery, and don't charge it indiscriminately.
- Charger quality assurance
Choose a regular charger with quality assurance, and don't use an inferior charger.
- Charging time control
The charging time should not be too long, properly control the charging time, and do not overcharge the battery.
- Charging environmental conditions
Choose a dry, ventilated, dark environment for charging, and keep the charging environment temperature appropriate.
- Security awareness
After charging, it is necessary to pull out the plug in time to avoid short circuit and safety accidents.
In short, the battery of the battery swapping station can be charged by itself, but it is necessary to pay attention to the relevant charging knowledge and precautions to ensure that the charging is completed safely and effectively.
7. Conclusion
Swappable battery is a convenient and practical battery, lead-acid battery and lithium-ion battery are two of the current mainstream swappable batteries, and lithium-ion batteries are favored because of their large capacity, fast charging speed and high safety.
During use, we also need to pay attention to the capacity of the battery, charging speed and other information to better use and maintain our battery.
