열화 방지 배터리 번역(영어 번역본)1. How does MaxLife prevent degradation? Batteries have different chemistry depending on their manufacturer or type. A battery’s performance also differs depending on how long it has been used. MaxLife’s fuel gauge prevents battery degradation by giving appropriate directions depending on the type or life of a given battery. For example, degradation can easily occur if an old battery is charged quickly. MaxLife takes this into consideration and prevents degradation by charging a battery rapidly when a quick charge is requested, and otherwise charging it slowly. 2. If there are so many different types of battery, does the charging chipset also require a separate algorithm depending on the characteristics and type of a battery? Charging technology has already been developed since laptop technologies. Starting 8-9 years ago, TI has conducted relevant tests by investing over a million dollars, and as a result, possesses over 500 pieces of battery chemistry information. Therefore, almost all battery information that are released in the market are contained in a MaxLife product by default. If a new battery is developed, TI receives the relevant information from the battery’s manufacturer and releases a chipset on which this information is applied to the market. 3. How does MaxLife reduce charging time? Does it increase charging current? Or does it use a different method? Basically, it charges quickly by increasing the charging current. However, quick charging by unconditionally increasing the current can raise the possibility of degradation. Therefore, MaxLife provides three chipsets depending on battery size, and lowers the current if the battery temperature rises due to quick charge to prevent degradation and extend battery life by. By monitoring the battery using an impedence tracking algorithm, which accurately detects the battery status, Maxlife sends the optimal charging current to minimize degradation. 4. Doesn’t the technology for managing battery with a fuel gauge already exist? That’s correct. It’s a technology that has been applied in laptops for a long time. But up to now, the functionality of the gauge was limited to monitoring the remaining amount of the battery, and did not separately call for a charger. MaxLife distinguishes itself by having this gauge directly call the charger and prevent degradation. 5. How fast does it charge compared to other existing products? General mobile phones are charged at 3.1A in an hour, and smartphones can be charged at 1C. However, this can cause the battery to easily degrade, so smartphone manufacturers design their products such that the battery is charged at 0.6C by default. MaxLife can charge rapidly at 1.2C, which is twice as fast, depending on the battery status or user demand. For example, it can quickly charge if the device needs to be used for an urgent task, or charge slowly at night when there is enough time to charge. Also, the micro-controller built inside the gauge includes an authentication functionality, which enables it to detect and react to the use of battery that is not genuine. For situations when the battery warms up while being charged or a problem occurs, it can find the cause of the problem because all log data are stored. 6. Is this product used as one for each cell? Or is it one for the entire battery? First of all, MaxLife is a product that is applied to single cell products. Even if there are many batteries, only one gauge is necessary. This is because the gauge already has the respective chemical information stored in it. The biggest difference between laptop and smartphone batteries is that the fuel gauge is mandatorily required in a laptop. Because it can cause a major problem if the system crashes while performing an important task, a feature to accurately measure the remaining amount is included. On the other hand, until only two years ago, mobile phones before smartphones did not require a fuel gauge feature. However as the capability of smartphones becomes more diversified and complicated, a fuel gauge is being mandatorily demanded like the laptop. You can think of it as transferring the technology in laptops to smartphones. For your reference, the laptop also only requires a single gauge that stores respective chemical information. 7. Qualcomm uses an application to manage battery. From a user’s perspective, it seems that Qualcomm’s product is more attractive. What do your opinion on this? Qualcomm’s technology is only applicable on their own chipset. However, TI’s battery management technology is applicable to all products regardless of the chipset. I’m also aware that while Qualcomm supports rapid charging, it doesn’t provide functionality to extend the overall battery life. In addition, it must receive information from the gauge in order to conduct battery management with an application. Considering that TI provides a gauge that enables this functionality, it is difficult to compare with Qualcomm’s technology. 8. When will a product that applies this technology be launched? We have completed tests with major OEMs for the past 6 months, and already launched in the market. Some OEMs also completed design that applies MaxLife. 9. Does the effect apply in the same manner even when you interrupt the charging of a smartphone, use the device, and then resume charging? Yes. This is because the TI fuel gauge continuously traces while being charged, or even when stopping and resuming to charge. The same effect can be obtained even if the battery is replaced with a new one because the fuel gauge recognizes it. 10. Third party chargers are used by many domestic smartphone users. Can third party chargers be used in the same manner? Because MaxLife is a built-in charger inside a mobile phone, any input can enter. Also, this built-in charger itself has functionality to monitor and control power source that flows into the device. For example, a 10W charger adapter must be used to charge a smartphone, but there are many adapters that fail to meet this condition in the case of third party chargers. In such case where an input that is lower than the operating range enters, MaxLife detects it and makes adjustment by loading more current so that optimal charging is performed. 11. Is there an advantage in terms of BOM, compared to other products? Because a charger and fuel gauge are products that have already been included in existing smartphones, the BOM does not increase nor decrease. However, while an external charger must be used for quick charging in smartphones, MaxLife can reduce costs by not requiring an external charger because it provides functionality for quick charging on its own. 12. How much market profit are you expecting? TI is an IC company. Solving problems that customers encounter is what we value the most. The biggest task for the smartphone market is that while the battery capacity must get bigger, and functionalities must get stronger as smartphones increase their features, the size of the battery must also get smaller. TI developed the MaxLife smart charging technology to solve this contradicted problem in the market, and to help customers’ designs. In fact, TI’s battery management technology already assumes a dominant position in the smartphone and laptop markets. Therefore, it is correct to view the purpose of this product as to share the result of TI’s battery management technology development with customers, rather than to make profit. |
