What are the reasons why a hybrid car cannot start?
2 Answers
Hybrid cars cannot start for the following reasons: 1. Issues with the ignition system or fuel line, which can be determined based on the cause of the shutdown; 2. The starter cannot rotate or has insufficient speed; 3. Loose or oxidized battery terminals; 4. Insufficient battery voltage, dead battery, or battery damage. Hybrid cars, also known as composite power vehicles, are equipped with more than one power source: batteries, fuel cells, solar cells, or generator sets of internal combustion locomotives. Currently, composite power vehicles generally refer to those with an internal combustion locomotive generator plus a battery. There are currently three main types of hybrid vehicles: 1. "Parallel mode," where the engine is the main power source and the electric motor serves as an auxiliary power source; 2. "Series-parallel mode," where the vehicle is driven solely by the electric motor at low speeds, and the engine and electric motor work together at higher speeds; 3. "Series mode," where the vehicle is driven solely by the electric motor, with the engine serving only as a power source. In this mode, the drive system consists solely of the electric motor, but a fuel engine is still required.
I've encountered the issue of hybrid cars not starting several times. The main reasons are often a dead small battery. Hybrid vehicles have a 12V auxiliary battery responsible for the starting system. If the car is parked for too long without being driven or the lights are left on, the battery can easily drain. Another issue could be with the engine part, such as aging spark plugs or a faulty fuel pump. The hybrid system requires coordination between both sides, and if the fuel line is blocked, it can cause a stall. Additionally, there might be a problem with the high-voltage battery. The high-voltage battery in hybrid cars powers the electric motor, and if there's an imbalance in charging or poor contact in the wiring, it may also prevent the car from starting. It's important to regularly check these parts, avoid leaving the car parked for extended periods without charging, and if any issues are found, it's best to drive directly to a 4S shop for professional inspection.
