Stromspeicherbatterie LTO 2kWh SolarTrack 50,6V/40Ah Einschub

Single battery Consisting of 1 or several cells connected in parallel to form a 2.3V monomer

of a lithium titanate battery pack.

BMS=BAM+FPA 。 It mainly collects the parameters of the single battery voltage, total voltage,

chargedischarge current, capacity, battery ambient temperature and other parameters of the lithium titanate battery pack, which is used to manage and balance the battery charging process and discharge process, and assists the effective protection and alarm function of the circuit system (protection and alarm function In terms of performance, BMS = BAM + FPA

Nominal Voltage: Used to represent an approximation of the average voltage of a battery pack in volts (V): 50.6V (22 single cells @2.3V in series).

Termination voltage: The voltage at which the cell battery/battery module/battery pack requires a stop discharge.

cycle life: Under specified conditions, the service life of the battery pack or the number of charge and discharge cycles that the battery pack can perform before a certain performance failure.

save rate of capacity: The battery pack has the ability to release usable capacity under the specified environmental conditions, after storing for a certain period of time, under the specified discharge conditions.

internal resistance Ri （Ω）(mΩ:

When current flows through a single cell/cell module/battery pack, the resistance value reflected by the voltage change at the output of the cell/cell/cell module/battery pack is expressed in Ri in ohms ( Ω) or milliohms (mΩ).

Environmental conditions of use

The working environment of the battery pack should be free of corrosive, explosive and insulating gas and

conductive dust, and away from high heat sources.

b: Temperature range：0℃～45℃

Working temperature range: 0℃～45℃：(≤3h/d) -10℃～0℃、45℃～60℃；-10C

Note: It can run in the temperature range of -10℃～0 ℃ and 45℃～ 60℃ within a certain period of time (recommended ≤3h/d); heat preservation measures should be taken below -10℃.

BMS -10℃～60℃，

When forming BMS components, the derating of each parameter should be considered within the temperature range of -10°C to 60°C, and the operation and accuracy of the BMS should not be affected.

c: Relative humidity range: Operating relative humidity range: ≤ 95% (45 ℃± 2 ℃ );

storage and transportation relative humidity range: ≤95% (45℃±2℃).

d: The atmospheric pressure range is: 70kPa～106kPa.

Battery packs with a capacity of 40Ah and below should be embedded in a 19-inch

standard cabinet with a width of 600mm and a height of a multiple of 1u. 1u=44.25mm.

The charging is in constant voltage and current limiting mode. The equalizing charging voltage of the single battery is 2.3V~2.9V, and the default value is 2.55V; the floating charging voltage of the single battery is 2.5V~3V, and the default value is 2.6V.

The 10h rate discharge current is represented by I10, the value is 0.1C10, and the unit is ampere (A).

Charging current constant current value: 1.0I10, 2.0I10, 2.5I10, 5.5I10, 10I10 are optional, the default value of charging current is 1.0 I10.

Discharge current value: 1.0I10～10I10 optional.

Discharge termination voltage value:

1.50V/cell ~ 2.90V/cell, the default value is 2.80V cell.

The current flow of each part of the battery pack should meet the maximum charge and discharge current: 10 I10A.

Note: 1. See Appendix A for the charging method.

There are two ways to judge that the lithium titanate battery pack is fully charged:

a) Under the condition of ambient temperature of 25℃±2℃,

charge with the current specified in 3.1.1, when the voltage of the battery pack reaches the equalizing charging

voltage specified in 3.1.1, change to constant voltage charging, and the total charging time is not less than 16h.

b) Under the condition of ambient temperature of 25℃ ± 2 ℃ , charge with the current specified in 3.1.1. When the voltage of the battery pack reaches the equalizing

charging voltage specified in 3.1.1, change to constant voltage charging until the charging current is less than or equal to 0.5I10A.
