Abstract
A battery swapping apparatus, an apparatus for diagnosing a battery condition, a method for diagnosing a battery condition, and a battery exchange system including the battery swapping apparatus and the apparatus for diagnosing a battery condition with high-efficiency and high-reliability are disclosed. The battery exchange system may discharge a battery pack in which charging has been stopped, calculate at least one state information of the discharged battery pack, resume charging of the battery pack, calculate the impedance information from the at least one state information of the discharged battery pack, and determine a state of health (SoH) of the battery pack and whether the battery pack is defective.
Claims21
A battery swapping apparatus comprising:
- a charger configured to charge a battery pack accommodated within the battery swapping apparatus;
- a discharger configured to discharge the battery pack;
- a sensor configured to measure state information of the battery pack;
- and
- a controller configured to, in response a state of charge of the battery pack reaching a predetermined reference value:
- stop operation of the charger;
- control the discharger to operate;
- and
- acquire the state information of the battery pack in a discharged state.
An apparatus for diagnosing a condition of a battery pack, comprising:
- at least one processor;
- and
- a memory having stored thereon at least one instruction executed by the at least one processor,
- wherein the at least one instruction causes the at least one processor to:
- receive and store state information of the battery pack;
- calculate impedance information based on the received state information of the battery pack;
- and
- calculate a state of health (SoH) of the battery pack from the impedance information.
A method for diagnosing a condition of a battery pack comprising:
- receiving and storing, by at least one processor, state information of the battery pack;
- calculating, by the at least one processor, impedance information based on the state information of the battery pack;
- and
- calculating, by the at least one processor, a state of health (SoH) of the battery pack from the impedance information.
