What Speeds Up Electric Vehicle Charging? Unveiling the Key Factors

Balancing Current, Voltage, and Portable Charging Stations with Precision

With the increasing popularity of electric vehicles, there is a growing demand for faster and more efficient charging. Charger power, typically measured in kilowatts (kW), is a crucial concept used to gauge the charging speed of electric vehicles. 

However, to truly grasp charging power, we need to consider two key factors: current and voltage, as well as the intelligent adjustment capabilities of portable charger stations.

1.Current, Voltage, and Charging Power

Before delving into charging power, let’s first understand the basic concepts of current and voltage:

Current

Current is the rate of electron flow and is usually measured in amperes (A). It represents the quantity of electrons passing through a circuit, with larger currents indicating faster electron flow.

Voltage

Voltage is the driving force behind electrical power and is typically measured in volts (V). 

It represents the pressure pushing electrons, with higher voltages exerting greater pressure.

Charging power can be calculated using the following formula:

Charging Power (megawatts, MW) = Current (amperes, A) x Voltage (volts, V)

This means that charging power is the product of current and voltage.

In traditional electrical systems, current and voltage are typically fixed, resulting in a fixed charging power.

2.Why does fast charging at DC charging stations shorten the battery life of electric vehicles?

When most electric vehicle owners pursue faster charging speeds, they usually choose to use high-power DC charging stations. This option does charge an EV quickly, but it can have a negative impact on the battery’s lifespan.

Simply put, the lifetime of an EV battery is the amount of time the battery can maintain high performance. Like other batteries, EV batteries degrade over time. 

However, when we use high-power DC charging stations for charging, the battery will be subject to greater current and voltage shocks, which will cause the battery to degrade faster, thus shortening the battery life.

So while fast charging can be very convenient in some situations, car owners need to weigh the relationship between charging speed and battery life. Using high-powered DC charging stations too frequently can result in reduced battery life, so charging options need to be carefully considered to maintain the long-term health and performance of your battery.

Intelligent Adjustment in Portable Charging Stations

However, for portable charging stations, the situation is different.

These charging stations often feature intelligent adjustment capabilities that allow them to adapt the current and voltage according to the electric vehicle’s requirements.

This intelligent adjustment enables the charging station to accommodate various types of electric vehicles and provide them with the appropriate charging power.
