On board charger ev 6.6kw hybrid TC portable electric vehicle charger

 on board charger

Charging an electric vehicle depends on three components, the speed of which is always determined by the weakest link in the chain. These three components are the charging station, charging cable, and on board charger. The least known of the three is the on board charger. So how does it work? What are the basic types of on board chargers? What are the future prospects?


The TC charger provides constant current or constant voltage charging, both are easy to operate. Each of them has its advantages and disadvantages. In the case of constant current charging, the efficiency is high and the charging speed is fast, but there is a risk that the battery will be overcharged in the later stage and its life will be shortened. In the case of constant voltage charging, there is a risk of too much current flowing into the battery at the outset, which can overheat the battery, again shortening its life.




 

In this way, the charger ensures that it is initially charged with a constant current, thereby maintaining speed and efficiency. When the voltage at both ends of the battery reaches a certain level, it will switch to constant voltage charging. This system is called a charging strategy and is the most important function of an on-board charger.

The word charger can be confusing. Since charging stations are commonly known as chargers, it should be noted that there are two types of chargers:

 

On-board charger (OBC) built into the car

Charging station (also known as charger, can be AC or DC) - Electric Vehicle Supply Equipment (EVSE)

In this article, we will discuss the topic of on board chargers, which are an integral part of every electric vehicle. Topics on external chargers (EVSE) and charging with DC or AC can be found here.

Why should I open the cover above the battery when charging an electric forklift?

  Why should I open the cover above the battery when charging an   electric forklift ? An electric forklift truck is an important logistics and transportation equipment that uses a battery as a power source. After use,  forklift battery  need to be charged to restore their energy. During the charging process, the cover above the battery needs to be opened, why is that? First of all, opening the cap on top of the battery is mainly to fully aerate the electrolyte inside the battery. The electrolyte of the battery is mainly composed of sulfuric acid and water, and when the battery is charged, hydrogen and oxygen will be produced. If the cap above the battery is closed, hydrogen gas will accumulate inside the battery, and as the charging time increases, the concentration of hydrogen gas will increase, which will lead to safety hazards. Once the problem occurs, it may cause fire, explosion, and other dangerous events. Secondly, you can also observe the electrolyte level b...

The High Power Density On Board Charger

图片
  In the race towards a greener future, electric vehicles (EVs) have emerged as a leading contender to revolutionize the automotive industry. However, one of the key challenges facing widespread EV adoption has been the need for faster and more efficient charging solutions. Enter the High Power Density  On Board Charger  (HPD-OBC), a groundbreaking technology poised to accelerate the transition to electric mobility. Traditional charging systems for EVs have typically been bulky and slow, limiting the practicality and convenience of electric vehicles. However, the advent of  high power on board charger  represents a significant breakthrough in charging infrastructure. By offering greater power output in a compact form factor, HPD-OBCs promise to drastically reduce charging times and enhance the overall usability of electric vehicles. So, what exactly sets HPD-OBCs apart from their predecessors? The key lies in their remarkable power density, which refers to the a...
