By understanding the common electric car terms found in dealer brochures or official websites, new users can easily interpret every EV specification. You won’t be confused when seeing range figures, battery capacity, or advanced safety features.

Moreover, this knowledge helps you choose the right electric vehicle for your needs whether for daily urban commutes or off-road adventures for modern urban explorers. By understanding terms like WLTP, kWh, or ADAS, you’ll also gain deeper insight into the technologies that enhance driving safety.

Essential Electric Car Terms You Need to Know

For new users, here’s a list of electric car terms that often appear in brochures:

1. EV (Electric Vehicle)

EV is a general term for electric vehicles, which includes several categories such as BEV, HEV, PHEV, and FCEV. So, when you hear the term “EV,” remember that not all are the same. Some are fully electric, while others still combine an electric motor with a gasoline engine.

2. BEV (Battery Electric Vehicle)

BEV refers to a fully electric vehicle powered solely by batteries, without any gasoline engine. Battery types vary, one of the most stable and durable types is the LFP (Lithium Iron Phosphate) battery, used in several Chery electric models.

Examples of BEVs include the Chery E5, an electric SUV offering up to 430 km of range (WLTP), and the Chery J6, available in both RWD and iWD configurations for various road conditions.

3. HEV (Hybrid Electric Vehicle)

HEV combines a gasoline engine with an electric motor. It’s a popular choice for those transitioning gradually from conventional to fully electric vehicles. HEVs are more fuel-efficient but cannot be recharged externally.

Chery’s HEV lineup, such as the Tiggo 8 CSH and the newly launched Tiggo 9 CSH introduced at GIIAS 2025, showcases modern hybrid technology that delivers both responsive performance and fuel efficiency, ideal for urban driving or long trips.

4. PHEV (Plug-in Hybrid Electric Vehicle)

PHEV is a more advanced hybrid since its battery can be charged externally. This means you can drive a certain distance using electric power before switching to gasoline when the battery is depleted.

5. FCEV (Fuel Cell Electric Vehicle)

Unlike BEV or PHEV, FCEV uses hydrogen as fuel to generate electricity. This technology is more common abroad, as Indonesia’s hydrogen infrastructure remains limited.

6. SoC (State of Charge)

SoC indicates the remaining battery capacity, it is similar to the battery icon on your smartphone. Related terms include overcharging (excessive charging) and overheating (battery overheating). To prevent these issues, modern EVs feature Battery Management Systems (BMS) and Thermal Management Systems, which automatically protect the battery and extend its lifespan.

7. WLTP & NEDC Range

These are standardized methods for measuring EV range. WLTP (Worldwide Harmonized Light Vehicles Test Procedure) provides more realistic results closer to real-world driving, while NEDC (New European Driving Cycle) tends to produce higher range figures. So, if you see an EV brochure claiming 430 km WLTP, that number is typically a more accurate estimate of the vehicle’s true range.

8. kWh (Kilowatt-hour)

This unit measures battery capacity. The higher the kWh, the longer the driving range, though higher capacity also means longer charging times.

Over time, batteries naturally experience degradation meaning their performance slightly decreases with use. While still safe to drive, range may gradually decline. That’s why easy access to battery spare parts should be a key consideration.

9. MPGe (Miles Per Gallon Equivalent)

MPGe compares the efficiency of an electric car with that of a gasoline-powered vehicle. In other words, it helps potential buyers understand how economical an EV is if measured in traditional fuel consumption terms.

10. tCO₂e (Ton Carbon Emission Equivalent)

This term represents the amount of carbon emissions reduced through the use of electric vehicles. The lower the tCO₂e, the smaller the vehicle’s environmental impact.

For instance, using an electric car for daily city commuting can reduce several tons of carbon emissions per year compared to conventional gasoline cars meaning every kilometer driven with an EV contributes to reducing the nation’s carbon footprint.

11. Regenerative Braking

Regenerative braking is an advanced system that converts wasted kinetic energy during braking into electrical energy to recharge the battery. This process improves efficiency and helps extend the vehicle’s range.

For example, when the driver slows down on a descent or in traffic, the system automatically channels some of that energy back into the battery which allows the EV to recover energy without external charging.

12. Fast Charging & Slow Charging

There are two main types of charging: AC Charging (Slow Charging) and DC Charging (Fast Charging). AC charging uses alternating current, it’s typically installed for home charging. DC charging uses direct current with high voltage, usually available at public charging stations, and can recharge up to 80% of the battery in just a few dozen minutes.

13. V2L (Vehicle to Load)

V2L is a trending feature that allows electric cars to function as a “giant power bank” for external devices. For example, you can power an electric stove or charge a laptop while camping. This feature is available in Chery E5 and Chery J6 electric SUVs, making them even more versatile and functional.

14. ADAS (Advanced Driver Assistance Systems)

ADAS refers to a suite of intelligent safety technologies that assist the driver while driving. Examples include Adaptive Cruise Control, Lane Keeping Assist, and Blind Spot Monitoring. In Chery’s electric SUV lineup, the J6 comes with 14 ADAS features, while the E5 is equipped with 17 ADAS systems, making it one of the most advanced in its class.

15. TKDN (Local Content Requirement)

Lastly, TKDN (Tingkat Komponen Dalam Negeri) is a mandatory local content requirement for EVs to qualify for government subsidies. Currently, Chery’s electric SUVs have achieved a 40% TKDN rating, making them eligible for Indonesia’s EV incentive programs.

The suspension system is one of the most crucial components in maintaining driving comfort and stability, especially if you own an SUV designed for large capacity, family use, and diverse road conditions. This system absorbs shocks, maintains balance, and ensures the tires stay firmly in contact with the road surface.

Although SUVs are known for their toughness, their suspensions still require regular maintenance to maintain optimal performance. For those who frequently drive on uneven city roads or semi-off-road terrains, proper suspension care will greatly enhance both comfort and safety while driving.

This article provides a simple, practical guide on how to maintain your SUV suspension for longer lifespan and maximum comfort. From checking shock absorbers to the importance of wheel alignment and balancing, here are key steps you can follow to keep your SUV’s suspension in top condition.

1. Check Shock Absorbers Regularly

Shock absorbers are the main dampers that stabilize your vehicle when driving over bumpy or uneven roads. If they start to weaken, you’ll notice excessive bouncing, “thudding” sounds underneath the car, or visible oil leaks around the suspension area.

This usually happens due to loosened bolts or joints. If you spot signs of leakage or damage, have your car checked by a trusted mechanic immediately to avoid further issues. Generally, shock absorbers should be inspected every 10,000–20,000 km, and replaced every 50,000–80,000 km depending on driving conditions.

2. Avoid Overloading the Vehicle

Every SUV has a maximum load capacity set by the manufacturer. Exceeding this limit can shorten the lifespan of the suspension and place excessive strain on the undercarriage components. As a result, springs may sag faster, shock absorbers wear out prematurely, and ride comfort decreases.

For example, the Chery Tiggo 9 CSH, a seven-seater SUV, is designed to carry families and luggage comfortably over long trips. Meanwhile, the Chery J6 is ideal for semi off road use thanks to its strong and stable suspension structure. Still, avoid overloading to keep the suspension performing optimally.

3. Inspect Bearings and Bushings Regularly

Bushings act as dampers that reduce vibrations and noise between metal components in the suspension system. Bearings, on the other hand, reduce friction between moving parts and help stabilize the vehicle’s load.

Always ensure both components are in good condition, especially rubber bushings that may crack or harden over time. If they wear out, the car may vibrate, make unusual noises, or feel unstable when cornering. Routine inspections during scheduled maintenance help detect wear early.

4. Perform Wheel Alignment and Balancing

Wheel alignment and balancing are crucial for ensuring the wheels and suspension system are properly aligned. When the wheels are misaligned, the suspension works unevenly, accelerating tire and shock absorber wear.

Common signs your car needs alignment include a heavy steering feel, drifting to one side while driving straight, or noticeable vibrations at high speeds. By performing alignment and balancing every 10,000 km or after long trips, you can maintain both driving comfort and suspension longevity.

5. Use the Recommended Oil and Components

Shock absorber oil and replacement parts such as springs, bushings, or bearings should always meet manufacturer specifications. Using non-standard oils or parts can alter the suspension’s characteristics and reduce ride comfort.

For instance, Chery’s modern SUVs are equipped with MacPherson Strut, Torsion Beam, and Multi-Link Independent suspension systems designed to deliver premium-level comfort. Proper maintenance using the recommended components and fluids ensures these systems remain durable and perform optimally.

Why SUV Suspension Maintenance Matters?

Suspension is not just about comfort, it’s a critical safety component that ensures vehicle stability and control. It absorbs vibrations, distributes vehicle weight evenly, and keeps the tires in full contact with the road.

When neglected, worn suspension parts can make the car feel harsh and unstable, accelerate tire wear, reduce fuel efficiency, and even affect steering performance. Regular suspension maintenance not only preserves comfort but also ensures safety and efficiency on any road condition.

Signs Your SUV Suspension Needs Service or Replacement

If you notice any of the following while driving, it’s time to schedule a check-up at your car dealer or service center:

• Unusual noises from underneath the vehicle
• The car feels wobbly or unstable
• Steering feels imprecise
• Tires show uneven wear

Ignoring these signs can lead to further damage and compromise safety. Besides reducing comfort, worn suspension parts can affect other components as well. Regular inspections will help ensure your SUV stays in excellent condition.

If you own a Chery SUV, you can easily have your suspension inspected and serviced at the nearest authorized Chery dealer. Skilled technicians will ensure your vehicle’s suspension system performs according to factory standards, backed by attractive after sales support for every model. This way, you can enjoy a smooth, stable, and safe driving experience on all types of roads.

A spacious cabin, capacity for up to seven passengers, and large cargo space are some of the key advantages of SUVs. With these benefits, many people wonder how to save fuel when driving an SUV, especially when it’s used for daily commuting. SUVs are known for their power and comfort, but their fuel consumption is generally higher than smaller cars due to their heavier weight and larger engines. Combined with city traffic and frequent congestion, fuel expenses can quickly rise if not managed properly.

Fortunately, there are several ways to save fuel in your SUV without sacrificing comfort or performance. From simple driving habits to regular maintenance and taking advantage of modern vehicle technology, you can make your SUV more efficient. Here are some practical tips to get started.

1. Maintain Proper Tire Pressure

One of the simplest yet most effective ways to improve fuel efficiency is by keeping your tire pressure at the manufacturer’s recommended level. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel.

You can check tire pressure at gas stations or use a portable pressure gauge. Keep it within the ideal range (typically around 32–35 psi, depending on the SUV model). Check your tires every two weeks or before long trips. Proper tire pressure not only improves fuel efficiency but also extends tire life and maintains vehicle stability.

2. Avoid Sudden Acceleration

Aggressive driving habits such as hard acceleration or sudden braking can significantly increase fuel consumption. The engine burns more fuel to produce quick bursts of power.

Try to drive smoothly and maintain consistent speed. This not only makes your drive more comfortable but also reduces stress on the transmission and brakes. Many modern SUVs come with an Eco Mode feature that adjusts engine output for smoother, more efficient throttle response, especially useful in heavy city traffic.

3. Watch the Vehicle Load

The heavier your car, the more fuel it consumes. Avoid carrying unnecessary items in the trunk or installing heavy accessories like roof boxes or spare tire mounts unless needed.

Although SUVs are designed to handle heavy loads, carrying excessive weight puts extra strain on the engine and suspension. This not only reduces fuel efficiency but also accelerates wear on key components. Always bring only what’s necessary for your trip.

4. Perform Regular Maintenance and Oil Changes

Never skip oil changes during maintenance. Dirty or overly thick oil increases engine friction, forcing it to work harder and burn more fuel. Most modern SUVs now use low friction synthetic oil, which improves both engine performance and efficiency.

Synthetic oils (for turbocharged engines) provide better protection under extreme temperatures while also extending engine life and ensuring stable performance under various driving conditions.

5. Use the Right Driving Mode for the Road

Many modern SUVs come with multiple driving modes such as Eco, Normal, and Sport. Each mode adjusts the engine’s performance and responsiveness.

• Use Eco Mode for daily city driving to maximize efficiency.
• Normal Mode is ideal for highway trips, offering a balance between power and fuel economy.
• Sport Mode should only be used when maximum performance is needed, such as overtaking or driving uphill.

Selecting the right mode helps optimize fuel use without compromising comfort

6. Take Advantage of Start-Stop Engine Technology

Start-Stop systems automatically turn off the engine when the vehicle stops at traffic lights or in jams, then restart it when you press the accelerator. This feature helps reduce fuel waste during idling.

Several modern Chery SUVs are already equipped with this technology, helping drivers save more fuel in congested city areas and making their drives more efficient.

7. Avoid Long Idling

Leaving your engine running while stationary still burns fuel unnecessarily. If you’re waiting for more than three minutes, such as in a parking lot or rest area, it’s better to turn off the engine. This simple habit can save a few percent of fuel over time, especially useful for SUV drivers who often take long trips.

8. Use the Recommended Fuel Type

Using the wrong fuel grade can reduce engine efficiency, cause knocking, and even damage the combustion system. Always follow the manufacturer’s recommended octane rating (RON) for your SUV.

While high-octane fuel may cost slightly more, it ensures cleaner combustion, better performance, and long-term engine protection. Over time, this can reduce maintenance costs and maintain optimal performance.

By following these tips, you can identify and reduce the habits that waste fuel in your SUV. Remember, fuel efficiency isn’t just about the engine or technology, it also depends on your driving behavior.

For a more efficient and eco-friendly driving experience, consider modern SUVs from Chery, which feature Eco Mode, electric SUV, and hybrid systems, and intelligent technologies designed to support a smart and energy saving lifestyle.
