Description

{Reusable battery data collection apparatus and method thereof}

The present invention relates to an apparatus and method for collecting recycled battery data. More specifically, the present invention relates to a device and method for collecting recycled battery data. More specifically, it is possible to control charging and discharging for a plurality of reused batteries, and to evaluate the performance of the recycled battery by individually collecting battery data for each recycled battery. It relates to a device and method for collecting recycled battery data.

The government is implementing eco-friendly policies and new and renewable energy supply policies, and is pursuing development centered on new and renewable energy in accordance with eco-friendly policies and new and renewable energy supply policies.

Following this trend, the need and usability of Energy Storage Systems (ESS), which store electricity and use it when needed, are increasing.

Battery purchase costs account for a large portion of the cost of building ESS.

Typically, new batteries are purchased and applied when building ESS, and as necessity and usability increase, the amount of expansion and construction of ESS is also increasing.

As ESS continues to be expanded and newly constructed, various ways to reduce the construction, expansion, and maintenance costs of ESS are being studied.

One of these plans is to recycle batteries from electric vehicles and apply them to ESS.

In general, electric vehicles are also rapidly commercialized in accordance with the government's eco-friendly policy, and their sales are increasing.

These electric vehicles use batteries that do not produce exhaust as a power source. Typically, when the battery of an electric vehicle becomes less than 80% of its initial capacity, the driving speed range is significantly limited and must be replaced.

Therefore, it is predicted that the number of waste batteries from electric vehicles will increase rapidly in the near future, and it is predicted that more than 10,000 waste batteries will be generated annually after 2024.

In this way, the batteries used in electric vehicles cannot be used in electric vehicles, but can be applied to ESS because approximately 70% to 80% of the capacity can be used. Accordingly, methods and technologies for recycling waste batteries from electric vehicles by applying them to ESS are being actively discussed.

However, the efficiency varies depending on the characteristics and past use history of the battery to be recycled (hereinafter referred to as “recycled battery”), so to ensure the efficiency and performance of ESS using recycled batteries, the current status of the recycled battery must be measured, collected, and evaluated. Technology is becoming important.

When charging and discharging, the voltage, current, and total voltage of the battery cell are controlled. Battery data to evaluate the performance of the recycled battery 10 is collected by measuring the voltage and current information of the recycled battery.

As described above, the conventional recycled battery data collection device allows the user to directly check the internal information of the recycled battery 10 whose performance is to be measured through the battery cell information acquisition unit 20, and transmit the confirmed internal information to the battery charging and discharging unit 30. Since data can only be collected after setting it in ), there is a cumbersome problem from the user's perspective. In other words, the conventional recycled battery data collection device can collect data only after the user goes through several steps, which poses a cumbersome problem for the user.

In addition, in the conventional recycled battery data collection device, the number of recycled batteries 10 that can be connected is limited depending on the number of channels of the expensive battery charging and discharging unit 30, and the performance of a plurality of recycled batteries 10 exceeds the number of channels. In the case of evaluation, there was a problem that the cost of building a data collection device increased because an expensive battery charging and discharging unit had to be provided.
