The charger can charge lithium iron phosphate batteries and ternary lithium batteries
Lithium iron phosphate and ternary lithium are the main raw materials for electric vehicle batteries, which are used for battery energy storage.
Let's compare lithium iron phosphate and ternary lithium from the following aspects.
First is energy density. Energy density is the biggest disadvantage of lithium iron phosphate batteries. According to a paper from the University of Pennsylvania, the energy density of a single lithium iron phosphate battery is about 180Wh per kilogram, while the energy density of a ternary lithium battery can exceed 250Wh per kilogram. Don't underestimate this 30% difference. One-third of the weight of an electric vehicle and nearly 40% of its cost come from batteries. The 30% gap is almost fatal for high-end cars. Even if the performance of low-end and mid-end cars is not well controlled, it will look very poor.
In addition, the low-temperature performance of lithium iron phosphate batteries is not ideal. In a zero-degree environment, the effective battery life of lithium iron phosphate batteries is only 58% of that of ternary lithium batteries. If the temperature drops to -10 degrees, only 30% of the battery life will be left. Of course, this is data obtained without any obvious thermal management adjustments. If the battery can be insulated and heated, the battery life will be higher than this.
Applications of the On Board Charger (OBC)
The applications of electric vehicle onboard chargers are vast and varied. They are widely used in personal EVs, commercial fleets, and public transportation systems. They are also commonly used in emergency services, where rapid charging is crucial for maintaining critical operations. Additionally, onboard chargers are an integral part of home EV charging stations, making it easy and convenient for EV owners to charge their vehicles overnight.
