Do Hybrid Cars Need to Be Charged? Here's the Explanation

As electrified vehicles grow in popularity across Indonesia, many prospective drivers are still asking the same question: do hybrid cars actually need to be charged?

Hybrid cars themselves have emerged as an efficient transition solution, combining the performance of a petrol engine with the quiet refinement of an electric motor, without requiring drastic changes to driving habits.

So, how does the charging mechanism in these vehicles actually work? Read on for a comprehensive breakdown of how hybrid car charging systems work, along with practical tips for keeping them in top condition.

What Is a Hybrid Car?

Before answering the question of whether hybrid cars need to be charged, it is worth understanding what a hybrid car actually is.

A hybrid car is a vehicle that combines a conventional combustion engine with an electric motor to drive the vehicle. This combination makes the car more fuel-efficient, reduces emissions, and still delivers strong overall performance.

While driving, the car can operate on electric power at lower speeds, while the combustion engine takes over when more power is needed, resulting in journeys that are both more economical and more environmentally responsible.

Do Hybrid Cars Need to Be Charged?

So, do hybrid cars actually need to be charged? The answer depends on the type of hybrid car in question. Each type has a different charging mechanism, which means their maintenance requirements and charging needs differ as well.

1. Full Hybrid (HEV)

This type of vehicle does not require manual charging via an external power source at all. Its battery charging system is self-sufficient, or self-charging. Electrical power is generated through two main methods:

• Regenerative Braking: A system that converts kinetic energy, typically lost during braking, into electrical energy, storing it back in the battery.
• Engine Generator: The petrol engine itself acts as a generator, automatically recharging the battery whenever sensors detect that power levels are running low.
  
  

2. Plug-in Hybrid (PHEV)

This type represents a blend of conventional hybrid vehicles and fully electric vehicles. Unlike HEVs, PHEVs are equipped with significantly larger battery capacities, meaning they both need to be and can be charged via an external power source.

With a fully charged battery, the vehicle can travel in electric-only mode for a considerable distance. However, if the battery runs out mid-journey, the vehicle automatically switches to standard hybrid mode, continuing on the petrol engine.

3. Mild Hybrid (MHEV)

Similar to the HEV system, Mild Hybrid vehicles do not require manual charging. In these vehicles, the electric motor is not capable of driving the car on its own; instead, it functions as an assist, supporting acceleration and reducing the workload on the petrol engine.

The battery in this type of vehicle is recharged automatically, so drivers do not need to worry about external charging, while still enjoying smoother acceleration and improved fuel efficiency.

Tips for Keeping Your Hybrid Car's Battery and Engine in Top Condition

Now it is time to explore some practical maintenance tips for keeping your hybrid car's engine and battery performing at their best. Here are several tips you can put into practice.

1. Check Oil and Engine Condition Regularly

Because hybrid engines frequently start and stop automatically, using the correct oil as specified by the manufacturer is essential to preventing wear on internal components.

Make sure to regularly check and change the oil according to the service schedule. This simple routine helps maintain optimal engine performance and extends the lifespan of your hybrid vehicle.

2. Monitor and Maintain the Battery Cooling System

A hybrid car's battery needs to maintain an optimal operating temperature to function efficiently. You should ensure that the specialised coolant in the hybrid system is replaced regularly, every 40,000 km.

In addition, keep the air vents in the cabin area free of dust buildup. If air circulation becomes blocked, the battery temperature can spike, potentially shortening the overall lifespan of your hybrid battery.

3. Avoid Overcharging the Battery

For those driving a Plug-in Hybrid (PHEV), try not to leave the battery either completely empty or fully charged at 100% for extended periods while the vehicle is parked.

To help prevent degradation, make a habit of driving regularly so that the battery's charging and usage patterns remain balanced.

4. Avoid Flooded Roads and Wash Your Car Properly

Although all electrical components are designed to be water-resistant, it is still important to exercise caution during the rainy season. Avoid driving through flooded areas where the water level reaches the battery components or high-voltage cables.

When washing the vehicle, make sure not to direct high-pressure water directly to sockets or electrical components under the hood.

5. Inspect the Regenerative Braking System Regularly

Unlike conventional vehicles, hybrid cars rely on regenerative braking to recharge their batteries. This typically means the physical brake pads last longer, as the electric motor assists the braking process.

Even so, regular inspections at an authorised service centre remain essential, to ensure that the braking sensor system and energy conversion mechanisms remain properly synchronised and fully functional.
