With the arrival of summer, the temperature continues to rise, which is really unbearable. In addition to the hot summer, summer is also a rainy season. In the face of high temperature and rainy summer, people can hardly stand it, not to mention lithium battery packs, both afraid of high temperature and afraid of rain.lithium ion battery assembly When using lithium batteries in summer, in addition to the use of the original lithium battery charger, what are the other issues that need attention when using lithium batteries in summer?

Summer can use lithium battery packs to pay attention to safety matters

1. Do not carry lithium battery packs in high temperature sunshine place

When used in summer, pay attention to the safety of lithium batteries as much as possible. Due to the hot weather, the battery has been heating up in the process of use, so the battery safety hazard is a big problem, which can easily lead to spontaneous combustion of the battery.battery cell machine Be sure to pay attention to the ventilation and heat dissipation of the battery to avoid the battery being exposed to the sun.

2. Lithium-ion battery packs do not charge in a high-temperature environment

Lithium-ion batteries produce overcharging during high temperature operation.prismatic cell assembly Elevated temperature will increase the activity of each active substance and the reaction will be full and strong, resulting in fast reaction rate during charging, high charging current and high temperature as well as lower charging voltage required during charging.

3. Do not overcharge lithium battery packs for long periods of time

Lithium batteries have no memory effect. Each charge lasts about 5-8 hours. Please estimate the time of using the battery and prohibit overcharging.

4. Keep the lithium-ion battery dry

If water enters the battery compartment, it may cause a direct short circuit between the positive and negative terminals. The least serious consequence is damage to the battery, while the most serious may directly lead to short circuit, combustion, or even explosion.

5. Lithium battery pack installation should be under the guidance of technical installation

Lithium battery installation is a professional behavior, it is best to install under the technical guidance or professional assistance.

6. Lithium battery packs do not empty storage of electricity

Lithium battery packs are not allowed to be stored without electricity. If the lithium battery pack is not suitable for short time use, please charge the battery to more than 50% for storage and charge the battery every 30 days.

Four common methods of heat dissipation for lithium battery packs

1. Structural isolation, plus lithium battery cell bracket

2. Lithium battery BMS protection board to add heat sinks

Lithium battery BMS protection board in the charging and discharging process, the MOS tube will be hot, the heat will be transmitted to the battery cell, resulting in the entire battery pack temperature becomes high. So we see in many lithium battery pack combination structure, will be isolated lithium battery protection board installed, if not isolated, will add a heat sink on the protection board, so that the protection board heat dissipation faster.

3. Configuration, the choice of high-capacity batteries, high-current protection plate

You can choose to increase the capacity of the battery, reduce the discharge rate, increase the discharge capacity of the protection board to control the temperature rise of the whole discharge.

4. Space to join the heat dissipation technology equipment devices

For large lithium battery pack equipment, you can do is to join the space on the cooling equipment devices, such as electric fans, such as large power lithium battery pack in the water cooling system, and large storage lithium battery pack container in the air conditioning, etc., are in addition to a set of equipment, so that the lithium battery pack cooling.
