Description:
BATTERY USAGE SCORING SYSTEM

TECHNICAL FIELD

The invention relates to the scoring system which displays usage quality of the battery in any device powered by accumulator, battery or battery packs.

The invention specifically relates to scoring system which displays quality of the battery comprising the process steps of obtaining data pertaining to the operation conditions such as the amount of amps drawn by the battery, accumulator and battery packs, the operation temperature and operation duration and of obtaining a BAX numerical magnitude that is calculated with the collected data and that increases every second at every instance of the operation.

STATE OF THE ART

Battery may be defined as a device that stores electrical energy as chemical energy, and supplies it as electrical energy on demand, which is also referred to as accumulator. Because of the batteries in today's advanced electronic devices from computers to smart devices, we can store electrical energy in our devices and use our devices without requiring any electrical power from power socket as long as the energy stored therein lasts. Amount of energy stored in the battery cells gives the total capacity of battery. Capacity of a battery is expressed in mAh. The higher the value is, the higher the capacity of a battery is. The fact that how battery is used constitutes a great importance in terms of the lifespan of the battery (cells). Batteries, which are essential energy sources of portable devices, get weakened as a result of loss of active substances therein and undesired chemical or physical changes. Particularly, rather than defining, in a month or year-wise manner, the life concept of rechargeable cells used in devices such as mobile phones, tablets, lap-top, it would be more accurate to refer it as cycle quality (cycle life). Accordingly, a charging (loading) and subsequent discharging (unloading) process corresponds to the term "cycle". It may be simply emphasized that the disposable or namely non-rechargeable type of batteries has only one cycle life. On the contrary, depending on the chemical structure of the battery, it is possible to achieve 500-1500 cycles in rechargeable type of batteries. As a result of each cycle, the battery loses some of its capacity of nominal energy at the beginning and when the capacity is reduced to 60-70% in comparison to the beginning, this means that the battery has run out of its life for that particular device. The definition of battery life encompasses also the notion of internal resistance. As the batteries are used over time, the internal resistance thereof starts to increase and generally when the internal resistance increases 1,3 - 2,0 times in comparison to the beginning, this means that battery has run out of its life. However, due to the fact that it is quite difficult to measure the internal resistance at the present time, it is generally accepted that it is based on the number of cycles in detecting its life.

Almost all charging systems on the market charge the battery cell, accumulator and battery systems connected thereto by assuming that these systems have been used in good conditions. Though, the conditions of usage greatly vary upon the user, time and ambient temperature for the same device, machine or vehicle.

In the state of art, the main problem of charging systems is that they consider all battery cells, accumulators or battery systems connected thereto equivalent, regardless of their usage background. Because no information is provided to the charger devices to accept otherwise. Even the users are not aware of how the difficulty level of the operation affects the battery cell/battery quality.

Consequently, it is required a development in the art regarding the need of a new economical, useful scoring system that displays the usage of the batteries and the inefficiency of the existing solutions for the solution of the above-mentioned problems in the state of the art.

OBJECT OF THE INVENTION

The invention, which is set forth because of the current cases and aims to solve the above-mentioned drawbacks, relates to a scoring system which displays usage of the battery in any device powered by battery or battery packs.

The main object of the invention is to classify battery, battery cell and accumulators by converting the factors experienced by batteries during the usage and shortening battery life into a penalty score.

Another object of the invention is that said penalty score of batteries (with cells) used in devices, machines and vehicles is not only an indicator for how harshly or mildly these batteries are used, but also a decisive factor for that device, machine and vehicle.

The structural and characteristic features and all advantages of the invention will become clearer with the figures attached and the detailed description with reference to these figures, and therefore the evaluation should be made taking these figures and detailed description into consideration.

FIGURES FOR A BETTER UNDERSTANDING OF THE INVENTION FIGURE-1; illustrates the inventive battery usage quality scoring system.

DETAILED DESCRIPTION OF THE INVENTION This detailed description is related to the inventive scoring system which displays usage quality of the battery in any device powered by battery or battery packs.

The battery usage scoring system shown in Figure- 1 classifies batteries used based on their usage. The invention is based on a processor and a data collector unit that are for the purpose of external usage or which are embedded into the body of the battery cell, accumulator or battery systems. However, nature, circuit details, processor type, memory capacity of said miniature data collector system and if it is embedded in the battery do not constitute any importance.

This data collection system is installed either in a single cell battery, accumulator, battery, or it is coupled to the group thereof so as to last a lifetime. This data collection device converts the temperature, the drawn current and the usage period calculated during usage into a penalty score.

Because of this systematic, the factors which are experienced by batteries during the usage and which shorten battery life will be converted into a penalty score and thus a classification of the battery, battery cell and accumulators will be provided.

Said penalty score of batteries (with cells) of devices, machines and vehicles will not only be an indicator on how harshly or mildly these batteries are used, but also it will be a decisive factor for that device, machine and vehicle.

In the present invention; data collector follows the operating conditions such as the amount of amps drawn, operation temperature and operation time of the cell battery, accumulator or battery pack until end of the system life. It enables penalty score called as BAX by supplying an instantaneous current, temperature and time information. It is compact and economic. It contains a microcontroller and an integration.

BAX (Battery Abuse Index), This index is a numerical magnitude calculated with the data collection of a data collector that is coupled to the battery or battery pack such that it is integrated into the battery pack throughout the battery life, and that increases every second at every instance of operation.

BAX is a cumulative quality measure of heavy or light operation conditions applied to any battery or battery pack. BAX is calculated with the formula BAX =åAt |T-231 H(dA/dt) according to the data obtained. It increases in the direct proportion with the drawn current and the change of current over time. In any case, an increase of the battery temperature enhances the penalty score. The parentheses which encompasses the temperature expression is an absolute sign of value and is always positive. These instantaneous values increase and accumulate throughout the life of the system. Also, it serves as a kind of km counter. The symbol å is based on total, the symbol H is based on the Heaviside function, the symbol A is based on ampere, and the symbols dA/dt are based on the time derivative of the current. Heaviside function doesn't take negative accelerations into consideration.

MAX: (Machine Abuse Index), this index gives an additional penalty index used with BAX and that can be adapted to the device, machine or vehicle. It is calculated with the formula MAX = k (BAX). Because of this index, a quality and penalty index of usage conditions of not only battery or battery packs, but also of device, machine or vehicles which comprise said battery or battery packs is produced. It is determined by multiplying with a coefficient k for the machine, device or vehicle. In cases where this expression is more complex, different formulas may be employed.

The present invention comprises following procedure steps;

- obtaining data of operating conditions such as the amount of amps drawn, operating temperature and operating time of the cell, accumulator or battery pack,

- obtaining a BAX numerical magnitude that is calculated with the collected data and that is increasing every second at every instance of operation.

The present invention provides a BAX-based special penalty systematic in electric cars wherein said systematic may be customized for the user. BAX may be provided on the vehicle front panel, in addition to other information on the dashboard. Insurance companies, car rental companies or fleet management will be able to set prices based on this application and rate their users.

By means of the present invention, charging devices which are to charge batteries, battery cells and accumulators may safely determine their charging policies according to BAX. Thus, the battery, battery cell or accumulator charge will not remain the same and standard for all battery cells, batteries and accumulators, regardless of their background usage; on the contrary, the charging time, current and voltage will be determined individually depending on the background and quality of usage of the unit to be charged. Optimum charging policies will be determined on a battery basis.

Each of BAX and MAX included in the present invention are a penalty score systematic based on usage. These are the basic indexes that may be taken into consideration when trading vehicles, devices and machines with batteries. The distance of a vehicle in km, for example, does not provide any information on the quality of the driving. However, in an electrical vehicle, BAX and MAX index values are an indication of whether the driving was safe or out of respective norms. Furthermore, BAX and MAX values may be the most decisive factors in trading of secondary market vehicles in addition to the km information of vehicle.

The protection scope of the invention is defined in the attached claims and shall not be construed as limiting with the above described features which are provided to be only illustrative. It is clear that a person skilled in the art can execute the novelty of the invention by using similar embodiments and/or apply this embodiment to other areas of similar purpose used in the art. It is therefore obvious that such embodiments will lack the criterion of novelty and in particular the overcoming of the prior art.
