48v lithium ion battery Advantage

a. Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.

b. Long life-cycle: Can be circularly used, more than 2000 times recycles, 8 times of Lead acid battery.

c. Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.

d. Good performance at high temperature and high temperature resistance

e. Low self-discharge rate, less than 3% monthly.

f. No memory effects and highly efficient charge.

g. Environment friendly: Clean and Green energy poses no pollution on our environment.

Battery Performance

1.Electrical characteristics

NO.ItemRequirementsTest Method
1DischargerateperformanceDischarge Capacity/Nominal capacity×100%A) 0.3C5A ≥100%B) 1.5C5A ≥90%

a)Standard charge at 0.3C5A under the condition of normal atmospheric pressure and the

environmental temperature of 20°C±5°C and45%~80% RH, discharge at 1I3/4.5I3(A)to

2.0V or the cut-off voltage which is specified in the technical document of the company.

b)the capacity(AH)=the discharge time*discharge current,and then is described the percentage of the nominal capacity(Charge/discharge cycle can be conducted for 3times before meeting the Standards(the samebelow).

2High-lowTemperatureDischargeperformanceDischarge Capacity/Nominal capacity×100%A) 55 °C ≥95%B) -20°C ≥55%

After Standard charging. Then store it at the constant temperature of 55±2°C for 5h(of -20±2°C for 20h),and discharge at 0.3C5A to 2.0V or the cut-off voltage which is specified in the technical document of the company,the capacity(AH)=the dischargetime*

discharge current,and then is described the percentage of the nominal capacity.

3NormalStorage/HighTemperatureStorageResidual Capacity≥Nominalcapacity*80%Recoverable capacity≥Nominal capacity*90%

Store for 28 days(Store for 7 days at the constant temperature of 55±2 °C)after standard charge, then measure final status and residual capacity

at 0.3 C5A to 2.0V or the cut-off voltage which is specified in the technical document of thecompany;After charge/discharge(0.3C5A/0.3C5A)cycle can

be conducted for 3 times,recoverable capacity will be tested.

4StoragePerformancerecoverablecapacity ≥nominalcapacity *95%

Standard charge and then rest for 1H,then discharge for 2H at0.3C5A,storge for 90 days at 20°C±5°C,After standard charge,then discharge at 0.3C5A,(Charge/dischargecycle can be conducted for 5 times before meeting the Standards (the same below)

5Cycle LifeDischarge Capacity≥Nominal capacity*80%

Conduct 0.3C5A/0.3C5A cycle for 2000 times.The

discharge capacity shall be measured after 2000 cycles.

2.Safety Performance

NO.ItemRequirementsTest Method
1Over chargeNo fire,no explosionAfter standard charging,then Charge at 3C5A to 10.0V
2Over dischargeNo fire,no explosion

After standard charging,discharge 0.3C5A to 0V at 20°C±5°C

Short Circuit

at Room Temperature

No fire,no explosion

After standard charging, keep the battery into a ventilation cabinet and short-circuit the positive and negative terminals directly (general resistance shall

be less than or equal to 5mΩ) for 10 minutes

4Drop

No fire,no explosionno leakage

After standard charging, then let it self fall off from a height of 1.5m(the lowest height)to a rigid wooden board with the thickness of 20mm. The drop is implemented one time for every face.

5Hot OvenNo fire,no explosion

After standard charging. Keep the battery in the box with constant temperature of 85°C±2 °C and remained for 2hours at this temperature.

6CrushNo fire,no explosion

After standard charging, keep the battery on the bracket1. Extrusion direction:Perpendicular to the direction of maintaining pressure on the battery plates.2. Extrusion headdress product:≥20cm3. Extrusion degree: Until the battery shell ruptured or internal short circuit (battery voltage becomes 0V)

7NeedlepunctureperformanceNo fire,no explosion

After standard charging, keep the battery on the bracket,penetrate through it with a 3mm~8mm diameter nail near the center of its biggest surface

at the rate of 10mm/s-40mm/s.
