What Causes Frequent Burnout of Electric Vehicle Chargers?
1 Answers
Short circuits in the charger output line or internal short circuits between the battery's positive and negative terminals. Below is relevant information about electric vehicle chargers: 1. Charging Operation: When charging, first connect the battery, then plug in the power supply. After charging is complete, first disconnect the power supply, then unplug the battery. If the battery plug is removed first during charging, especially when the charging current is high (indicated by a red light), it can easily damage the charger. 2. Classification: Common switch-mode power supply chargers are divided into two main categories: half-bridge and single-ended. Single-ended chargers are further classified into forward and flyback types. Half-bridge chargers are more expensive but perform better, often used in chargers with negative pulse functionality. Single-ended chargers are more cost-effective and have a higher market share.
