What type of current did early electric vehicle chargers supply?

Early electric vehicle chargers primarily supplied direct current (DC) to charge the vehicles. This was largely due to the early design of electric vehicles and the electrical systems in use at that time. DC current was simpler to implement for charging batteries, as it allowed for straightforward battery storage methods without the need for complex conversion systems.

At the onset of electric vehicle technology, the systems utilized batteries that were inherently designed to be compatible with DC. This meant that charging stations were built to provide DC current directly to these batteries, ensuring efficient energy transfer and charging capability.

The transition to alternating current (AC) systems occurred later, as AC became more prevalent in the electrical grid and charging stations evolved to become more versatile. However, the initial chargers relied on DC due to the limitations and technologies available at that time. Thus, understanding the context of early charging systems is critical in grasping how charging technology has evolved over the years.
