Abstract
Provided is a battery pack charging system including a charging device configured to receive a first signal from a battery pack and determine a charge condition of the battery pack based on the first signal; a battery pack configured to generate the first signal based on a state of charge of the battery pack and transmit the first signal to the charging device; and a controller configured to receive a second signal from the charging device and transmit the second signal to the battery pack.
Claims11
A battery pack charging system comprising:
- a charging device configured to receive a first signal from a battery pack and determine a charge condition of the battery pack based on the first signal;
- the battery pack configured to generate the first signal having a waveform based on a state of charge of the battery pack and transmit the first signal to the charging device;
- and
- a controller separated from the charging device and from the battery pack, comprising a first controller port electrically coupled to the charging device and a second controller port different from the first controller port and electrically coupled to the battery pack, electrically coupled between the charging device and the battery pack via the first and second controller ports, and configured to receive, via the first controller port, a second signal comprising information about a state of the charging device from the charging device and transmit, via the second controller port, the second signal to the battery pack,
- wherein the state of the charging device is a current state of the charging device,
- wherein the information about the current state of the charging device comprises information related to at least one selected from current charging voltage and current charging current,
- wherein the controller is provided in a vehicle, the battery pack is provided in the vehicle and is further configured to supply electrical energy to the vehicle, and the charging device is provided separately from the vehicle,
- wherein the vehicle comprises a charging port to electrically connect the charging device to the vehicle,
- wherein the charging port comprises:
- a first port to electrically connect the battery pack to the charging device;
- and
- a second port to electrically connect the controller to the charging device,
- wherein the battery pack is to transmit the first signal to the charging device through the first port, and
- wherein the controller is to receive the second signal from the charging device through the second port.
