HIMAX is one of the leading battery manufacturers in Asia. It provides a series of battery pack charger solutions, including chargers for AA and AAA nickel metal hydride or lithium iron phosphate batteries (LiFePO4 Battery), and multi-slot chargers for lithium-ion 18650 battery packs. And customized lithium battery pack chargers, etc. If you want to know more about battery pack chargers, contact us now.
The choice of battery pack charger housing material requires comprehensive consideration of a variety of factors, including durability, weight, cost, heat dissipation performance, appearance, etc. The casing of HIMAX’s battery pack charger focuses on factors such as lightness, appearance diversity, and price, and it is made of plastic.
In addition, for customers with high requirements, HIMAX can provide customized services and choose some new composite materials, such as carbon fiber, glass fiber, etc., which have higher strength and durability, and are also relatively light in weight.

When choosing a lithium/LiFePO4 battery charger, you can consider the following key factors:

  1. Charging voltage range: Make sure the charger output voltage matches the battery-rated voltage. If the voltage is too high, the battery may be overcharged, reducing battery capacity or even causing an explosion; if the voltage is too low, the battery may be undercharged and unable to provide sufficient power to electrical appliances, thus affecting the battery life.
  2. Charging current control: Choose a charger with appropriate current control to adapt to different types and capacities or voltages of lithium batteries. Too much current may damage the battery, while too little current may cause charging to take too long.
  3. Protection function: Chargers with overcharge protection, over-discharge protection, short-circuit protection, and temperature control protection are safer and can effectively protect the battery.
  4. Power selection: Choose the appropriate power according to battery capacity and charging time. It is generally recommended to choose a charger with 1/3 to 1/2 of the lithium battery capacity, so as to ensure safety without being too slow. If you need to charge quickly, you can choose a charger with a higher power, but you need to pay attention to safety issues during the charging process.
  5. Interface type: Understand the interface type of lithium battery charger, such as JST, XH2.54, PH2.0, SM, XT60, etc., in order to choose a charger suitable for your device.
  6. Safety performance test: Understand the safety performance test results of the charger, such as the detection of overcharge protection, overcurrent protection, short circuit protection, and other functions, to ensure that the safety of the battery and the user can be protected in a timely and effective manner under abnormal circumstances.
  7. Environmental adaptability: Consider the working performance of the charger under different environmental conditions, such as the impact of temperature, humidity, vibration, drop, and other factors on its stability and reliability.

Different makes and models of chargers may have different storage requirements. When storing HIMAX battery pack chargers, pay attention to the following points:

  1. Environmental requirements. The storage environment should be dry and well-ventilated to prevent moisture or overheating inside the charger. Generally speaking, the storage temperature should not exceed 25℃ and avoid direct sunlight. In addition, avoid rain, moisture, dust, etc. from entering the charger and affecting its normal operation. If the charger needs to be stored for a long time, it is recommended to use a dust bag or box for packaging.
  2. Store safely. The charger should be stored out of the reach of children to avoid misuse or damage.
  3. Prevent falling and collisions. The charger should be handled with care when storing and avoid falling or collision to avoid damage to its internal components.
  4. Avoid not using it for a long time. If the charger is not used for a long time, it is recommended to charge and discharge it every once in a while (such as one month) to maintain its performance.
  1. Charging. Generally, when the battery charger is red and green, it means it is charging. Battery charging follows a certain sequence, first constant current charging, then constant voltage charging. When the light turns green, it needs to be charged for another 5 minutes, so as to protect the battery.
  2. If the converter inside the charger is damaged and cannot supply power to the electric vehicle normally, the traffic light will flash when the electric vehicle is charging. At this time, a new charger needs to be replaced.
  3. If the charger interface is loose, the battery cannot be charged through the power supply, and the green indicator light of the charger will flash.
  4. If the battery is aged, the green indicator light of the charger will also flash. This is because the number of charge and discharge times of the battery has reached the upper limit, exceeding the battery life.
The service life of a battery pack charger is affected by many factors, so it’s impossible to give a specific number. The service life of HIMAX’s battery pack charger is generally 2 to 3 years. HIMAX’s battery pack charger is made of high-quality electronic components, which can better ensure its long service life.
The working principle of the lithium battery pack charger is to achieve safe and efficient charging of the battery through the control circuit and power conversion circuit. At the same time, the charger also needs to have a variety of protection functions to ensure that the battery will not be damaged during the charging process.
As a professional battery manufacturer, HIMAX reminds that the voltage of lithium iron phosphate battery (LiFePO4) is nominally 3.2 volts, the full voltage is 3.65V, and the maximum voltage cannot exceed 3.8V. The voltage standard of ternary lithium-ion battery is 3.7V to 4.35V, which is far higher than the voltage standard of lithium iron phosphate charger. In addition, the two batteries also have differences in energy density, charging speed, safety, operating temperature, etc., and the charging voltage and protection circuits of the two chargers are different, so they cannot be used universally.
