Abstract

Apparatuses and methods for transmitting and receiving data are disclosed, where an apparatus for transmitting data includes a calculator configured to calculate a difference value between a reference value and a measurement data of a battery, and a transmitter configured to transmit an initial value and the difference value.

Claims

1. An apparatus for transmitting data, the apparatus comprising:

a processor configured to

measure, at a first time interval, measurement data of a battery;

calculate a difference between an initial reference value and the measurement data of the battery;

update the initial reference value to a value of the measurement data at the first time interval in response to a criterion being met, to generate an updated reference value; and

transmit either the difference or the updated reference value to a battery management device.

2. The apparatus of claim 1, wherein the measurement data is continuous data that changes over time and comprises any one or any combination of any two or more of voltage data, current data, or temperature data.

3. The apparatus of claim 1, wherein the initial reference value comprises a previous value of previous measurement data measured at a time interval occurring before the first time interval.

4. The apparatus of claim 1, wherein the criterion is an update interval.

5. The apparatus of claim 1, wherein:

the criterion is the difference exceeding a threshold range; and

the processor is further configured to transmit, in response to the difference exceeding the threshold range, the updated reference value to the battery management device.

6. The apparatus of claim 5, wherein the threshold range is expressible using one byte.

7. The apparatus of claim 1, wherein the processor is further configured to transmit the updated reference value or the difference over a controller area network (CAN).

8. The apparatus of claim 1, wherein the processor is further configured to:

in response to the initial reference value being updated, transmit the updated reference value to the battery management device; and

in response to the initial reference value not being updated, transmit the difference to the battery management device.

9. A method of transmitting data, the method comprising:

measuring, at a first time interval, measurement data of a battery;

calculating a difference between an initial reference value and the measurement data of the battery;

updating the initial reference value to a value of the measurement data at the first time interval in response to a criterion being met, to generate an updated reference value; and

transmitting either the difference or the updated reference value to a battery management device.

10. The method of claim 9, wherein the measurement data is continuous data that changes over time, and comprises any one or any combination of any two or more of voltage data, current data, or temperature data.

11. The method of claim 9, wherein the initial reference value comprises a previous value of previous measurement data measured at a time interval occurring before the first time interval.

12. The method of claim 9, wherein the criterion is an update interval.

13. The method of claim 9, further comprising:

the criterion being the difference exceeding a threshold range; and

transmitting, in response to the difference exceeding the threshold range, the updated reference value to the battery management device.

14. The method of claim 13, wherein the threshold range is expressible using one byte.

15. The method of claim 9, wherein the transmitting of the updated reference value or the difference is performed over a controller area network (CAN).

16. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 9.
