Baterie musí dosáhnout dostatečné hustoty výkonu (W/kg), aby distribuovala dostatečný proud k dosažení cílů zrychlení elektrických vozidel. Vysoká hustota výkonu (Wh/kg) může zároveň dosáhnout delší životnosti baterie nebo cestovního dosahu.
Proč je důležité sledovat teplotu baterie?
Most of today's rechargeable batteries are Lithium-ion batteries, and they have an operating temperature range of 15 degree to 35 degree , where they have the highest performance and highest capacity.
· If the battery is used in an ambient temperature lower than 15 degree , the electrochemical reaction rate in the battery will decrease, and the performance of the battery will decrease and the capacity will decrease. · If the battery or battery pack is used in an ambient temperature above 35 degree , the battery will gradually age faster. You may experience reduced battery life, uneven aging due to uneven temperature distribution, increased safety risks, and more, resulting in higher life-cycle costs. If the temperature is too high, the battery may even burst and cause leakage, smoke, fire or even explosion.
