After a jump start, it usually takes about 20 minutes for the car to run normally. When the car battery is dead, an external power source is needed to start the engine by connecting the positive terminal of the battery to the positive terminal of the power source and the negative terminal of the battery to the negative terminal of the power source. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Batteries can be divided into conventional batteries, dry-charged batteries, and maintenance-free batteries. Typically, when people refer to a car battery, they mean a lead-acid battery. The plates of a conventional battery are made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The full name of a dry-charged battery is a dry-charged lead-acid battery, which is characterized by the negative plate having a high capacity for storing electricity. In a completely dry state, it can retain the stored charge for up to two years.

Does the Tayron GTE have a three-electric warranty?

The Tayron GTE has a three-electric warranty. For new energy vehicles, the three-electric components refer to the motor, power battery, and electronic control system, which can be considered the core components of a new energy vehicle. Motor: The motor is the power source of a new energy vehicle. Based on structure and principle, motors can be divided into three types: DC drive, permanent magnet synchronous, and AC induction, each with different characteristics. Power Battery: The power battery is the energy source for driving the motor. Currently, power batteries are mainly distinguished by their cathode and anode materials, including lithium cobalt oxide, ternary lithium, lithium manganese oxide, and lithium iron phosphate. Ternary lithium and lithium iron phosphate batteries are more commonly used in new energy vehicles. Electronic Control System: The electronic control system is actually a general term, which can be further divided into the vehicle control system, motor control system, and battery management system.

What causes severe shaking during cold starts in the Sagitar?

Severe shaking during cold starts in the Sagitar is directly related to the fuel injection system, ignition system, and idle control system. It is recommended to have it inspected at a professional repair shop as soon as possible. The primary reason for shaking during cold starts is low temperature, where the engine's internal temperature is insufficient, requiring more fuel injection during cold starts to meet performance demands. The new Sagitar is a spacious A+ class comfortable sedan that combines German craftsmanship with modern dynamic styling. While inheriting Volkswagen's design language, the new Sagitar incorporates the minimalist and practical Bauhaus art design style, giving it a more modern and dynamic appearance. The Sagitar's body dimensions are 4544mm in length, 1760mm in width, and 1461mm in height, with a wheelbase of 2578mm.
