Lithium Ion Battery For Solar Street Light Main Advantages
- Waterproof Aluminum Alloy Shell: The solar street light lithium
battery is used outside, so we have to adapt to all kinds of
weather. Here we use IP67 aluminum alloy shell, which is
waterproof, collision-proof and fire-proof to ensure adequate
battery safety.
- Integrated Design: The controller can also be placed outside,
simply leaving two cables outside, one connected to the solar panel
and the other to the light, making the assembly work easier.
- Less parallel connections
- More durable
Over 2000 cycle times
Lithium Ion Battery For Solar Street Light Production Process
- Capacity separation of lithium battery cells: All cells should be
divided for the second time to ensure the full capacity of the
battery.
- Battery pack: The internal resistance and voltage of the battery
core are paired in groups to ensure that all internal resistance
and voltage of the whole battery pack are consistent, and the
products with higher safety and quality can be achieved
- Bracket combination: The battery pack adopts the safest bracket
combination, so the heat dissipation effect of the battery pack is
better and more reliable.
- Battery spot welding: Spot welding with pure nickel sheet has the
advantages of small internal resistance, large over-current and no
heating.
- Battery management system: Highland barley paper is used for
insulation protection and safety protection when the battery is
connected; The protection board has the functions of overcharge
protection, over discharge protection, over-current protection and
balance protection; It has no memory effect and can be charged and
discharged at any time
- Aluminum alloy shell packaging: The battery pack is packed with
IP67 aluminum alloy shell, which not only makes the appearance
beautiful, but also makes the safety protection of the battery not
to be ignored.
- Battery test: Battery aging test, charge discharge cycle test, we
guarantee to do the best quality to customers.
