光储那通事丨户储电池关键参数详解—纳通Turbo H3系列产品

A Detailed Explanation of the Key Parameters of HV Residential Storage Batteries – Taking RENAC Turbo H3 as an example

户用储能又称家庭储能系统，类似于微型储能电站，对用户而言，供电保障性更高，且不受外部电网影响。在用电低谷时间，户用储能中的电池组可自行充电，以备用电高峰或断电时使用。

Residential energy storage system, also known as household energy storage system, is similar to a micro energy storage power station. For users, it has higher power supply guarantee and is not affected by external power grids. During periods of low electricity consumption, the battery pack in household energy storage can be self-charged for backup use during peak or power outages.

在户用储能系统中，储能电池是价值最高的部分，关系到负载的用电量和功率。储能电池的技术参数非常重要，读懂并掌握技术参数的含义，可以最大化利用储能电池的性能，降低系统成本，为用户创造更大的价值。下面以纳通能源Turbo H3系列高压锂电池为例，解读关键参数。

Energy storage batteries are the most valuable part of a residential energy storage system. The power of the load and the power consumption are related. Technical parameters of energy storage batteries should be carefully considered. It is possible to maximize energy storage batteries' performance, reduce system costs, and provide greater value for users by understanding and mastering technical parameters. To illustrate the key parameters, let's take RENAC's Turbo H3 series high-voltage battery as an example.

1. 电气参数

Electrical Parameters

1) 额定电压：以Turbo H3系列产品为例，电芯串并联方式为1P128S，故额定电压为3.2V*128=409.6V。

Nominal Voltage：Using Turbo H3 series products as an example, the cells are connected in series and parallel as 1P128S, so the nominal voltage is 3.2V*128=409.6V.

2) 电芯容量：电芯容量是指电芯存储电量的大小，单位是安时（Ah）。

Nominal Capacity：A measure of the storage capacity of a cell in ampere-hours (Ah).

3) 额定容量/可用容量：电池额定容量是指在一定的放电条件下应该放出的最低限度的电量；电池可用容量，是指考虑到放电深度，实际可以使用的容量。锂电池放电深度（DOD）最大可以到90%，所以额定容量为9.5kWh的电池，实际充放电的容量是8.5kWh。在设计时，要用8.5kWh这个参数。

Nominal Energy：

In certain discharge conditions, the battery's nominal energy is the minimum amount of electricity that should be released. When considering the depth of discharge, the usable energy of the battery refers to the capacity that can actually be used. Due to the depth of discharge (DOD) of lithium batteries, the actual charge and discharge capacity of a battery with a rated capacity of 9.5kWh is 8.5kWh. Use the parameter of 8.5kWh when designing.

4) 电压范围：此电压区间需要与逆变器端电池输入电池区间相匹配，高压或低于逆变器端电池电压区间都会造成电池系统无法与逆变器配套使用。

Voltage Range：

The voltage range must match the input battery range of the inverter. Battery voltages above or below the inverter's battery voltage range will cause the system to fail.

5) 最大持续充放电电流：电池系统支持最大的充放电电流，决定了电池多久可以充满，此电流会受限于逆变器端口最大电流输出能力。Turbo H3系列最大持续充放电电流可达0.8C（18.4A），单块9.5kWh的Turbo H3 充放电功率可达7.5kW。

Max. Continuous Charging / Discharging Current:

Battery systems support maximum charging and discharging currents, which determine how long the battery can be fully charged. Inverter ports have a maximum current output capability that limits this current. The maximum continuous charging and discharging current of the Turbo H3 series is 0.8C (18.4A). One 9.5kWh Turbo H3 can discharging and charging at 7.5kW.

6) 最大电流：电池系统在充放电过程中，单位时间内达到的最大电流即峰值电流。Turbo H3系列峰值电流为1C（23A）。

Peak Current:

Peak current occurs during the charging and discharging process of the battery system. 1C (23A) is the peak current of the Turbo H3 series.

7) 最大功率：在一定的放电制度下，单位时间内电池输出的最大能量。Turbo H3系列最大功率为10kW。

Peak Power:

Battery energy output per unit time under a certain discharge system. 10kW is the peak power of the Turbo H3 series.

2. 安装参数

Installation Parameters

1）尺寸&重量

需要根据不同的安装方式，考虑地面或者墙面的承重，安装条件是否满足。需要考虑可用安装空间，电池系统长宽高是否会在此空间受限。

Size & Net Weight：

Depending on the installation method, it is necessary to consider the load bearing of the ground or wall, as well as whether the installation conditions are met. It is necessary to consider the installation space available and whether the battery system will have a limited length, width, and height.

2）防护等级

防水防尘最高等级。较高的防护等级意味着电池可以支持室外的使用。

Enclosure：

A high level of dust and water resistance. Outdoor use is possible with a battery that has a higher degree of protection.

3）安装方式

在客户现场如何安装，安装难度，如落地式/壁挂式安装。

Installation Type：

The type of installation that should be performed at the customer's site, as well as the difficulty of the installation, such as wall-mounted/floor-mounted installation.

4）冷却方式

以Turbo H3系列为例，设备自然冷却。

Cooling Type:

In the Turbo H3 series, the equipment is naturally cooled.

5）通讯

以Turbo H3系列为例，具备CAN和RS485通讯方式。

Communication Port:

In the Turbo H3 series, communication methods include CAN and RS485.

3. 环境参数

Environmental Parameters

1）环境温度范围

电池支持工作的环境温度区间范围。纳通Turbo H3系列高压锂电池支持的充、放电温度区间为-17-53℃，对于北欧等严寒地区的客户来说是不错的选择。

Ambient Temperature Range:

The battery supports temperature ranges within the working environment.  There is a temperature range of -17°C to 53°C for charging and discharging Turbo H3 high-voltage lithium batteries. For customers in northern Europe and other cold regions, this is an excellent choice.

2）相对湿度&海拔

电池系统可承受的最大湿度范围及海拔高度区间。对于一些潮湿或者高海拔地区需要关注此类参数。

Operation Humidity&Altitude:

Maximum humidity range and altitude range that the battery system can handle. Such parameters need to be considered in humid or high-altitude areas.

4. 安全参数

Security Parameters

1) 电池类型

主流电芯是磷酸铁锂(LFP)和镍钴锰三元(NCM)。与NCM三元材料相比，LFP材料更加稳定。纳通电池目前采用的就是磷酸铁锂电芯。

Battery Type：

Lithium iron phosphate (LFP) and nickel-cobalt-manganese ternary (NCM) batteries are the most common types of batteries. LFP ternary materials are more stable than NCM ternary materials. Lithium iron phosphate batteries are used by RENAC.

2) 质保年限

电池质保条款内容、质保年限及范围。具体内容可参阅《纳通电池保修政策》。

Warranty：

Battery warranty terms, warranty period, and scope. Refer to "RENAC's Battery Warranty Policy" for details.

3) 循环寿命

电池完整的充电和放电一次就称为一个循环，循环使用寿命是衡量电池寿命性能的一个重要指标。

Cycle Life：

It is important to measure the battery life performance by measuring the cycle life of a battery after it has been fully charged and discharged.
