Batteries can be discharged over a large temperature range, but the charge temperature is limited. For best results, charge between 10°C and 30°C (50°F and 86°F). Lower the charge current when cold. Nickel Based: Fast charging of most batteries is limited to 5°C to 45°C (41°F to 113°F).
When it comes to nickel-based chemistries, the temperatures cause issues with the hydrogen and oxygen combining. The building up of gases increases in pressure while the voltage drops as it may lead to venting. Heat impacts batteries in different ways as more damage occurs the higher the temperature rises.
Temperature rise and charge time constraint charging strategy is introduced. Genetic algorithm is wielded to optimize the charge current trajectories. The proposed method can reduce charge time notably with rational temperature rise. Battery charge performance and aging using the proposed approach are evaluated.
Charging a battery at low temperatures is thus more difficult than discharging it. Additionally, performance degradation at low temperatures is also associated with the slow diffusion of lithium ions within electrodes. Such slow down can be countered by altering the electrode materials with low activation energy.
