A closed-loop constant-temperature constant-voltage charging technique to reduce charge time of lithium-ion batteries. IEEE Trans. Ind. Electron. 2018, 66, 1059–1067. [ Google Scholar] [ CrossRef] Control core is more complex than an equalizer. Voltage limit of each cell is considered for increasing the charging rate.
Why does a battery need a temperature sensor?
In addition, the intrinsic temperature of a cell moves somewhat away from the temperature of the cell surface. This difficulty is solved with temperature sensing built-in. The number of temperature sensors needed for constant temperature constant voltage charging increases as the count of cells on the battery.
How does temperature affect battery charging?
The charging current is dynamically adjusted in response to the battery temperature, which indirectly reflects its aging and thermal environment. As per experimental results, the proposed method achieves 20% faster charging with the same total temperature rise as constant-current constant-voltage (CC-CV) technique.
What is a constant-temperature constant-voltage (CT-CV) charging technique?
This paper addresses this gap by proposing a constant-temperature constant-voltage (CT-CV) charging technique, considering cell temperature as a key degradation metric. The proposed CT-CV charging scheme employs a simple and easy-to-implement proportional-integral-derivative (PID) controller aided by a feed-forward term.
