Description:
A NEW GENERATION RECHARGEABLE SINGLE CELL BATTERY Technological Field:

The present invention relates to a new generation rechargeable single cell battery that exchanges information such as battery type, state of charge (SoC), charge-discharge number, thermal stress levels, manufacturer information, shelf life, production date with the charging device to which they are connected.

State of the Art:

Batteries are used in many important fields in the state of the art such as energy storage, electronic devices, electrical appliances etc. Today batteries, which can be formed in many different geometries such as cylindrical, bag and prismatic etc. can be recharged and used repeatedly by charging devices today. Rechargeable batteries are increasingly used in the electronic devices. In addition to conventional lead-acid, nickel-cadmium and nickel metal hydrate batteries, high energy density Lithium-based batteries are also available. Lithium-based battery family consists of batteries with different characteristic. The present invention describes a new rechargeable single cell battery.

Today, in the market of the battery (battery) charging device, there are separate charging devices for each battery type, with a limited part of which is relevant with the above mentioned batteries. In general, devices that can charge NiCd and NiMH batteries are different from the ones that can charge Lithium-based batteries. Although there is only one device that can charge Lithium-based batteries, Lithium-based batteries may also require different charging policies according to their capacities and voltage values. For this reason, the batteries must be introduced to the charging devices to which they are connected. In state of the art, battery detection, matching the correct battery with the correct charging device always depends on the user. If this matching is not performed properly, there may be security and financial damages. The charging devices that are known as universal charging devices and commercially available can charge all known and common batteries. However, the user introduces the type of the inserted battery to the device by him/her. In fact, after the introduction of the battery, the charging limits are mostly entered into the device by the user. In the state of the art, it is not always possible to measure the charging level from the voltage of the battery cells. The SoC value (battery charge level), which is called the state of charge, is calculated theoretically so as to understand this. The SoC value obtained by theoretical calculations does not always correspond to the actual SoC value.

In the state of the art, the cycles of batteries from fully charged to fully discharged are limited. Even under a proper charging operation, the economic life of the batteries is expressed in a few hundred charges. Battery cells can change their physical properties when exposed to overcharging or thermal stress. The most explicit change is in the form of swelling. However, this physical deformation is not always explicit. For this reason, the user shall be informed of the thermal stress and/or overcharging. Overcharged batteries carry a safety risk. In the US patent document numbered US20010000423A1 encountered in the literature research made, it is aimed to develop a portable device that can determine the battery chemistry without any user input and without any modification on the battery. The elements of the system used were not used in the battery structure. People purchase a portable device and measure their battery status. This situation provides a method that is not appropriate for the state of the art and is far from being practical. In the US patent document numbered US4965738A encountered in the literature search, it is aimed to access the battery state of charge (SoC), temperature information, and battery type value with a processor to be placed in the battery pack. Said method is not used in single cell rechargeable batteries.

In the US patent document numbered US4553081A encountered during the literature research made, a system that aims to monitor the properties of batteries such as capacity and usage time is developed. In said system, there is no design embedded in the body of single cell rechargeable batteries.

In the US patent document numbered US2016372801 (A1) encountered during the literature research made, an invention regarding rechargeable batteries is disclosed. The cylindrical batteries are arranged in a casing in the invention. An electronic circuit within the casing ensures access to state of charge of the batteries, voltage, current and other battery information and allows them to be displayed. In said document, it ensures the cylindrical batteries to be charged properly by accessing the state of charge, voltage, current and other battery information. However, these elements are not embedded in the batteries; they are placed in a casing.

In the Chinese patent document No CN205595419 (U) found in the literature research made, a cylindrical battery that can be accessed remotely is mentioned. Said battery is rechargeable and contains a remote access module. It also includes a processor and circuit so as to monitor the battery state of charge. It is mentioned that it is possible to access various data of the battery with the software found in smart mobile phones. The elements contained in the invention, determined charging device cannot access information regarding battery charge level (State of Charge, SoC), number of charging and discharging, thermal stress levels experienced, manufacturer information, shelf life, age etc. A battery is disclosed in the Chinese patent document numbered CN106785113 found in the literature research. This battery describes a battery structure with which remote access is possible. Furthermore, PWM control technology that regulates the input and output voltages of batteries is disclosed. In said document, some electronic equipment was found in the battery. Data exchange with the charging devices similar to the invention subject to description has not been encountered.

Consequently, a battery is required in which the state of the art is exceeded, the disadvantages are eliminated.

Description of the Invention: In this detailed description, the inventive battery (1) is described by means of examples only for clarifying the subject matter such that no limiting effect is created. In the description, a new generation rechargeable single cell battery (1) that exchanges information such as battery type, state of charge (SoC), charge- discharge number, thermal stress levels, manufacturer information, shelf life, production date with the charging device to which they are connected to is described. In Figure 1, Figure 2 and Figure 3, various perspective views of the cylindrical type single cell battery (1) in which the invention is applied are given.

Accordingly, the single cell battery (1) comprises a circuit positioned with an outer package (16) on the battery connection end (18) located at the upper end of the body (10) and numerous electronic components located on the circuit. Accordingly, there is a lower PCB layer (11) and an upper PCB layer (13) in the outer packaging (16) on the body (10). Since the dimensions of the cylindrical type batteries (1) are generally small, a two-layer circuit structure has been considered as more suitable. Flowever, the battery (1) can contain one, two or more PCB circuits. A microcontroller (12) is located on the lower PCB layer (11) in the invention. The voltage regulator (14) and memory chip (15) are located on the upper PCB layer (13). In the invention, there is a thermistor (19) in contact with the battery connection end (18).

In Figure 4 and Figure 5, various perspective views of the bag type single cell battery (1) in which the invention is applied are given. Accordingly, an additional outer package (16) is positioned at one end of the body (10) of the bag type battery (1). The outer packaging (16) contains a bag type battery PCB layer (17). On the bag type battery PCB layer (17), there is a microcontroller (12), a voltage regulator (14), memory chip (15) and a thermistor (19).

The microcontroller (12) used in the invention is preferably an 8-bit or 32-bit controller. The microcontroller is selected from the high energy efficiency class. The operating frequency operates at the lowest levels permitted by its manufacturer, at the levels of 20-30 KHz. In case the thermistor (19) is taken as 100K NTC, or equivalent, it is fed to the microcontroller (12) analogously. Either the charging current is cut off or it is cut on the main device to which it is attached based on the 60-70 C limits where the internal resistance of the thermistor (19) falls to a certain percentage of its initial value. The information of the manufacturer is stored by an external memory chip (15). This information contains the product serial code, the year of manufacture and other information, if any that the manufacturer requires to access. PCB layers (11, 13, 17) provide the energy supply they require from the battery (1) on which they are located. The controller operating voltage, 1.8 V, is regularly supplied through a reducer and voltage regulator (14).

In the invention, the PCB layers (11, 13, and 17) are in sleep mode when the battery (1) is not actively used. It switches to full functioning, because there is not any energy problem during charging. However, when the controller switches to the attached device after charging, the controller will only operate for a few seconds at very low sampling rates. The system is turned off for a while between measurements and calculations and then switches into sleep mode. During the operation, leaving the sleep mode is possible with a timer on the microcontroller (12). Periodically, the system switches between sleep and operation. Switching from an inactive period to the operation period is carried out by the cutting process created by the power flow. The invention has a software that transmits the product serial code, manufacturing year information found in the charge cycle and memory chip (15) on PCB layers (11, 13, 17) to the user (via a screen or an additional device) and the charging device. Therefore, the user knows how long he/she will use his/her battery (1), and the charging devices use the charging method optimized according to the battery (1 ) type.
