The power of new energy vehicles comes from power lithium batteries. Power lithium batteries are actually the power source for road transport vehicles. The main differences between it and ordinary lithium batteries are as follows:
Different properties
Power lithium batteries refer to batteries that power vehicles, generally involving portable electronic devices and small batteries; while ordinary batteries are primary batteries that use lithium metal or lithium alloy as negative electrode materials and non-aqueous electrolyte solutions, while lithium-ion batteries and lithium-ion polymer batteries in rechargeable batteries are different.
Different battery capacity
In the case of new batteries, use a discharge meter to test the battery capacity. Generally, the capacity of power lithium batteries is about 1000-1500mAh; while the capacity of ordinary batteries is above 2000mAh, and some can reach 3400mAh.
Voltage difference
Generally, the operating voltage of power lithium batteries is lower than that of general lithium batteries. The charging voltage of general lithium-ion batteries is as high as 4.2V, and the maximum charging voltage of lithium power batteries is about 3.65V. The nominal voltage of general lithium-ion batteries is 3.7V, and the nominal voltage of power lithium-ion batteries is 3.2V.
Different discharge power
A 4200mAh power lithium battery can be discharged in just a few minutes, but ordinary batteries cannot do this, so the discharge power of ordinary batteries cannot be compared with that of power lithium batteries. The biggest difference between power lithium batteries and ordinary batteries is their high discharge power and high specific energy. Since power batteries are mainly used for automotive energy supply, they have higher discharge power than ordinary batteries.
Different applications
The battery that provides driving power for electric vehicles is called a power lithium battery, including traditional lead-acid batteries, nickel-hydrogen batteries, and emerging power lithium-ion batteries, which are divided into power lithium-ion batteries (hybrid electric vehicles) and energy lithium-ion power batteries (pure electric vehicles); lithium-ion batteries used in consumer electronic products such as mobile phones and laptops are generally called lithium-ion batteries, in order to distinguish between power lithium-ion batteries for electric vehicles and power lithium-ion batteries for electric vehicles. Power lithium batteries for electric vehicles.
