环宇达电动汽车专用磷酸铁锂电池特点Characters of PTI LiFePO4 batteries used in Hybrid EV 电动汽车需要电池在其整个循环寿命中始终支持大电流的放电，为了达到这个要求， 传统电池需要有增大电池的尺寸和容量，从而保护电池的循环寿命。 很显然，增大电池尺寸并不是一个好的方案。磷酸铁锂电池能够支持大电流放电， 在比较小尺寸的情况下，达到高速电动汽车的要求，比较保证其超长的循环寿命,且安全性极高。HEVs require high power discharge and regen pulses, with very long cycle life. In order for traditional batteries to meet these demanding requirements, they must be oversized to protect battery life. However, oversizing, by definition, implies a larger than optimal battery. PTI shows low power loss with usage, allowing for a smaller battery that still meets end-of-life power.
