A sub-optimally designed battery pack reaches higher temperature fast and does not maintain temperature homogeneity. According to the best design practices in the EV industry, the temperature range should be kept below 6 degrees for a vehicle to perform efficiently. Fig 1. Cell Temperature for Case I
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).
Here are some general temperature guidelines for common battery types: – Lithium-ion (Li-ion) Batteries: The ideal charging temperature range for Li-ion batteries is typically between 0°C (32°F) and 45°C (113°F). Charging outside this range may result in reduced performance, decreased battery life, or even irreversible damage.
The thermal requirements of battery packs are specific. Not only the temperatures of the battery cells are important but also the uniformity of the temperature inside the battery cell and within the battery pack are key factors of consideration, in order to deliver a robust and reliable thermal solution.
Charging lithium batteries at extreme temperatures can harm their health and performance. At low temperatures, charging efficiency decreases, leading to slower charging times and reduced capacity. High temperatures during charging can cause the battery to overheat, leading to thermal runaway and safety hazards.
The recommended charging temperature range for NiCd batteries falls between -20°C (-4°F) and 45°C (113°F). – Nickel-Metal Hydride (NiMH) Batteries: NiMH batteries are also more tolerant of extreme temperatures. The suggested charging temperature range for NiMH batteries is generally between 0°C (32°F) and 45°C (113°F).
