公司有一个产品要做IEC 62368-1测试,然后说我们产品不符合M4.2条的要求,要我们整改,求助一下大佬们,这一项要咋测??????有啥测试方法可以指导一下吗??????
附上M4.2条款原文(中文翻译是机翻的):
M.4.2 Charging safeguards
M.4.2.1 Requirements
Under normal operating conditions, abnormal operating conditions or single fault conditions the charging voltage per secondary lithium battery and the charging current per secondary lithium battery shall not exceed the maximum specified charging voltage and maximum specified charging current.
在正常工作条件、异常工作条件或单一故障条件下,锂二次电池的充电电压和锂二次电池的充电电流不得超过最大规定充电电压和最大规定充电电流。
Under abnormal operating conditions, the battery charging circuit shall:
stop charging when the temperature of the battery exceeds the highest specified charging temperature; and
limit the current to the value specified by the battery manufacturer when the battery temperature is lower than the lowest specified charging temperature.
在异常工作条件下,电池充电电路应:
– 当电池温度超过规定的最高充电温度时停止充电; 和
– 当电池温度低于规定的最低充电温度时,将电流限制在电池制造商指定的值。
M.4.2.2 Compliance criteria
Compliance is checked by measuring the charging voltage, the charging current and the temperature of each individual cell of the secondary lithium battery under normal operating conditions, abnormal operating conditions and single fault conditions. The cell temperature shall be measured at the points specified by the battery manufacturer.
Single fault conditions that may affect the charging voltage or charging current or the temperature shall be applied in accordance with Clause B.4.
通过在正常工作条件、异常工作条件和单一故障条件下测量二次锂电池的每个单独电池的充电电压、充电电流和温度来检查合规性。 电池温度应在电池制造商指定的点进行测量。
可能影响充电电压或充电电流或温度的单一故障条件应按照 B.4 条应用。
NOTE 1 For potted assemblies, thermocouples could be attached to the cell surface before potting.
1 对于灌封组件,热电偶可以在灌封前连接到电池表面。
A higher charging voltage than the maximum specified charging voltage or a higher charging current than the maximum specified charging current, that occurs just after the introduction of an abnormal operating condition or a single fault condition, may be ignored if the operation of a protective device or circuitry, provided in addition to the normal regulating circuitry, prevents an unsafe condition of the battery.
如果除了正常调节电路之外提供的保护装置或电路的操作,防止了电池的不安全状态,则可以忽略在引入异常工作条件或单一故障条件之后发生的比最大指定充电电压或比最大指定充电电流高的充电电流高的充电电压。
Where appropriate, for the purpose of the measurement, the battery may be replaced by a circuit simulating the battery load.在适当的情况下,为了测量,可以用模拟电池负载的电路代替电池。
The charging voltage shall be measured when the secondary lithium battery becomes fully charged. The charging current shall be measured during the entire charging cycle up to the maximum specified charging voltage.
充电电压应在二次锂电池充满电时进行测量。 充电电流应在整个充电周期内测量,直至达到最大规定充电电压。
During and after the test, the following applies:
The charging voltage shall not exceed the maximum specified charging voltage.
The charging current shall not exceed the maximum specified charging current.
The charging of the battery shall stop when the temperature of the battery exceeds the highest specified charging temperature.
The battery charging circuit shall limit the current to the value specified by the battery manufacturer when the battery temperature is lower than the lowest specified charging temperature.
在测试期间和之后,以下内容适用:
– 充电电压不得超过规定的最大充电电压。
– 充电电流不得超过规定的最大充电电流。
– 当电池温度超过规定的最高充电温度时,电池充电应停止。
– 当电池温度低于规定的最低充电温度时,电池充电电路应将电流限制在电池制造商指定的值。
In addition, for equipment where the battery can be removed from the equipment by an ordinary person, compliance is checked by measuring the charging voltage and the charging current, and by evaluating the temperature control function of the equipment under normal operating conditions, abnormal operating conditions and single fault conditions.
另外,对于普通人可以将电池从设备上取下的设备,通过测量充电电压和充电电流,评估设备在正常运行条件、异常工况和单次故障条件下的温度控制功能,检查符合性。
All parameters controlled by the protection circuit for the battery shall be within those specified in the relevant IEC battery standard, and shall cover the following:
the maximum current drawn from the battery shall be within the range of the specification of the battery; and
throughout the tests, the battery temperature shall not exceed the allowable temperature of the battery as specified by the battery manufacturer.
电池保护电路控制的所有参数均应在相关IEC电池标准的规定范围内,并应包括以下内容:
– 从电池汲取的最大电流应在电池规格的范围内; 和
– 在整个测试过程中,电池温度不得超过电池制造商规定的电池允许温度。
NOTE 2 The controlling elements are voltage, current, and temperature.
2:控制要素是电压、电流和温度。
