DETERMINATION METHOD OF BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240014666 titled 'DETERMINATION METHOD OF BATTERY

Simplified Explanation

The present disclosure describes a determination method for identifying whether a battery is genuine or not. The method involves several steps:

1. Specifying Step: The state of the battery is determined by its state of charge (SOC) or voltage, represented as state x.

2. First Adjusting Step: The battery is adjusted to a state y by performing charge and/or discharge operations in state x.

3. First Measuring Step: The resistance value of the battery is measured in state y, which is considered as the first resistance value.

4. Second Adjusting Step: The battery is adjusted again to state y by performing charge and discharge operations after the first measuring step. The order of charge and discharge depends on whether the battery was adjusted from a high SOC/voltage side or a low SOC/voltage side in the first adjusting step.

5. Second Measuring Step: The resistance value of the battery is measured again in state y, considered as the second resistance value.

6. Determining Step: The genuineness of the battery is determined based on the comparison between the first and second resistance values.

Potential Applications:

  • Battery manufacturers can use this method to identify non-genuine batteries in the market.
  • Consumers can verify the authenticity of batteries before purchasing them.

Problems Solved:

  • Counterfeit batteries can be a safety hazard and may not perform as expected. This method helps in detecting non-genuine batteries, ensuring consumer safety and satisfaction.

Benefits:

  • Provides a reliable method for determining the genuineness of batteries.
  • Does not rely on the weight of the battery, which can be easily manipulated.
  • Can be implemented by battery manufacturers and sellers to prevent the distribution of counterfeit products.


Original Abstract Submitted

a main object of the present disclosure is to provide a determination method of a battery capable of determining a non-genuine product not basing on the weight of the battery. provided to achieve the object is a determination method of a battery for determining whether a battery is genuine or not, the method including: a specifying step of specifying, as a state of the battery, a state x defined by a state of charge (soc) or a voltage; a first adjusting step of adjusting a state of the battery to a state y by performing at least one of charge and discharge to the battery in the state x; a first measuring step of measuring a resistance value of the battery in the state y adjusted in the first adjusting step, the resistance value regarded as a first resistance value; a second adjusting step of adjusting a state of the battery to the state y again by performing charge and discharge to the battery after the first measuring step, the charge and the discharge correspond to below (i) or (ii): (i) when the battery is adjusted to the state y from a high soc side or a high voltage side in the first adjusting step, the charge and the discharge are performed in the order of discharge and charge so as to adjust the state to the state y again from a low soc side or a low voltage side; (ii) when the battery is adjusted to the state y from a low soc side or a low voltage side in the first adjusting step, the charge and the discharge are performed in the order of charge and discharge so as to adjust the state to the state y again from a high soc side or a high voltage side; a second measuring step of measuring a resistance value of the battery in the state y adjusted in the second adjusting step the resistance value regarded as a second resistance value; and a determining step of determining whether the battery is genuine or not based on the first resistance value and the second resistance value.
