Description

Technical Field

[0001] The present invention relates to the field of intelligent charging technology, and in particular to a fast-charging control circuit for a new energy light electric vehicle. Background Art

[0002] With the expansion of new energy technology applications in the field of special vehicles, mountain electric vehicles and off-road electric vehicles driven by small power batteries have been widely used in outdoor operations, off-road sports, etc. due to their high maneuverability and environmental adaptability. However, the battery charging control of these vehicles faces special challenges:

[0003] The contradiction between battery characteristics and charging efficiency: Small power batteries (such as high-energy-density lithium batteries) have limited capacity, and users have an urgent need for fast charging. However, the existing charging control circuit has problems with low energy conversion efficiency and high heat generation during fast charging. Especially in high-frequency usage scenarios such as mountainous and off-road, frequent fast charging can easily lead to battery life degradation, making it difficult to meet high-intensity operation requirements.

[0004] Insufficient charging stability in complex environments: Mountain and off-road electric vehicles are often in harsh environments such as bumps, dust, and humidity. The charging interface is prone to loosening or interference. Traditional charging circuits rely on the control method of electrical pulse contacts, which have the defects of large cable voltage drop and weak anti-interference ability, resulting in charging interruption or voltage sampling delay, and even impact on the battery due to fluctuations in charging parameters.

[0005] Lack of residual voltage handling and power outage response capabilities: During field operations, power supply may be interrupted by unexpected events such as generator failure or temporary power outages. Existing circuits are unable to effectively handle the residual voltage in the charging unit and voltage conversion unit, resulting in energy waste and potential battery safety hazards due to residual voltage accumulation. Furthermore, when the mains power suddenly fails, traditional systems struggle to switch to backup energy, resulting in charging interruptions and impacting vehicle range.

[0006] Precision control requirements under special operating conditions: When mountain electric vehicles climb hills or cross complex terrain, battery loads fluctuate significantly, requiring more dynamic regulation of charging voltage and frequency. Existing control circuits lack real-time and accurate monitoring of battery status and are unable to adjust charging parameters in a timely manner based on load changes in mountain and off-road scenarios, resulting in low charging efficiency and the risk of overcharging or over-discharging the battery.

[0007] Therefore, for the application of small power batteries in mountain and off-road electric vehicles, there is an urgent need for a fast charging control circuit with high anti-interference performance, residual pressure handling capability and power-off recharging function to meet the reliable charging needs in complex environments and improve battery life and vehicle endurance stability.
