What to Do When a Hybrid Car Battery Runs Out of Power?
2 Answers
Specific solutions for when a hybrid car battery runs out of power are as follows: 1. For plug-in hybrid electric vehicles (PHEVs) with a dead battery, simply drive it as a conventional fuel-powered car. 2. For hybrid vehicles primarily powered by fuel, theoretically, they cannot continue to drive when the battery is dead. 3. For range-extended hybrid electric vehicles (EREVs), the battery will not run out of power as the engine continuously charges the battery to ensure the motor has a continuous power output. Below is an introduction to the three types of hybrid vehicles: 1. Plug-in hybrid electric vehicles, commonly known as PHEVs. They are driven by two power systems, with three driving modes including motor drive, engine drive, and combined motor-engine drive. However, their pure electric range is short, and when driven solely by the engine, their fuel consumption is significantly higher than that of conventional fuel-powered cars. 2. HEV hybrid vehicles, where the power output is mainly from the fuel engine. At low speeds, they rely on the motor for power output, while the engine intervenes during acceleration and high-speed driving. 3. Range-extended hybrid electric vehicles, commonly known as EREVs. This type of hybrid vehicle differs from the above two, as its power mainly comes from the engine whether driving at low or medium-high speeds, but the motor plays the role of power output.
I've been driving a hybrid car for two or three years. Once after parking at a supermarket, it wouldn't start. After checking, I found out the 12V auxiliary battery was dead. This small battery is responsible for the starting system and electronic devices, and tends to cause problems as it ages. At that time, I used the jumper cables that came with the car to connect to a friend's car battery, and got it started quickly. Then I drove to the repair shop to replace the new battery. The technician said the hybrid's high-voltage battery doesn't affect starting, but this small battery must be checked regularly, especially since it drains faster in cold weather. Now I've developed a habit of testing the battery voltage every month and carrying a portable charger just in case. When the car isn't used for long periods, I also disconnect the battery terminals to avoid power drain. The hybrid system is quite convenient, but you can't neglect these small details.
