What do 'power' and 'charge' mean in Mercedes-Benz?

In Mercedes-Benz vehicles, 'charge' means: charging. 'Power' refers to energy or battery level. Although Mercedes-Benz is not a hybrid vehicle, various electronic devices in the car require electrical energy to operate normally without starting the engine in start-stop mode. Once the electrical energy is insufficient, the start-stop function cannot work. More details are as follows: 1. Meaning: The word 'charge' itself means charging. When it appears on the dashboard of a Mercedes-Benz, it indicates charging the start-stop battery. Engine start-stop means that during temporary stops, such as waiting at traffic lights, the engine needs to pause briefly while the lubricating oil continues to flow. This ensures that restarting does not cause damage to the engine. 2. Reason for charging: When the engine starts, it needs to supply power to the starter motor. The car battery frequently discharges to meet the power demands of the audio system and lighting. When 'charge' appears on the dashboard, the onboard charger is charging the battery, ensuring that even when the engine is not restarted during start-stop, the battery can still meet these power demands. Without this charging, even during a short wait at a traffic light, the car's audio and lighting systems would lose power and become unusable due to lack of energy supply.
I've been driving a Mercedes plug-in hybrid for almost two years now, and I frequently see the POWER and CHARGE indicators. Simply put, when the dashboard displays 'POWER' in blue, it means both the engine and electric motor are working together to accelerate, which is most common during uphill climbs or overtaking. That time I was rushing to catch a flight on the highway, I pressed the accelerator harder and saw it light up—the push-back feeling was quite noticeable. On the other hand, when 'CHARGE' appears in green, it's more reassuring—either the wheels are driving the motor to recharge while coasting, or the engine is actively replenishing the battery. I remember once on a long downhill stretch, just using brake regeneration brought the battery charge back up to 30%, which was quite practical. These modes switch intelligently on their own, so we don't have to worry about it. Understanding them makes the dashboard feel quite user-friendly.
Last week, I accompanied a friend to test drive the Mercedes-Benz C350e, and the salesperson specifically pointed out the POWER and CHARGE indicators on the dashboard. When POWER is lit, it means the car is in hybrid mode with both electric motor and engine working together to deliver maximum torque, allowing for quick acceleration from a standstill, like at traffic lights. CHARGE being lit indicates two scenarios: a flashing green light means kinetic energy recovery charging, such as when braking; a steady green light means the engine is generating extra electricity, and you can see the charging progress bar on the dashboard. My friend was initially concerned about fuel consumption during charging, but we found that using the engine to charge during highway cruising is three times faster than slow charging at home, making it very cost-effective in emergencies. The salesperson mentioned that the system defaults to prioritizing battery preservation, automatically switching to pure electric mode when the battery level is sufficient.
