Can an ESM be used in a Class C or D environment?

Ventilation VentilationThe ESM can be used in class A or B environments with direct ventilation butcannot be used separately in class C or D environments. If the ESM needs to beused in class C or D environments, cabinets with air conditioners and a high IPrating (IP55 or higher) must be deployed.

How many ESMs can be connected in parallel?

ESMs connected in parallel = N  x x Derating coecientcoecient x x Imax, whereImax is the maximum allowed ESM current. For example, if four ESMs are connected inparallel, the maximum current is 4 x 0.55 x 100 A = 220 A. Issue 01 (2020-06-30) Copyright © Huawei Technologies Co., Ltd. 9

How long should ESM be stored?

ESM In has applicationactual ESMU staticscenarios,power consumption andavoid storing anself-dischargeESM with lowlossSOCafter power-(≤ 5%). If unavoidable, limit the storage duration to 30 days at 25°C or 15 days at 45°C. Promptly recharge the ESM after the storage.

How do I re-charge my ESM?

Place the ESM in the original packing case. Mark the latestcharge time and the next recharge time (the next recharge time is 8 months (storedabove 30°C) or 12 months (stored below 30°C) later than the latest charge time) on thepacking case. Packed ESMs should be used as soon as possible. 2.

What happens if the ESM is burned?

The ESM is an enclosed battery system and will not release any gases undernormal operations. If the ESM is severely misused, for example, being burned or thunderstruck, theESM may be damaged, resulting in electrolyteelec trolyte leakage. Because the electrolyte isof organic carbonate nature, it may produce CO 2, CO, and N2 after being burned.

What happens if the ESM raises a Do2 overload alarm?

DO2 Overload If the ESM raises one of the following alarms, the drywarning, contact supplies an alarm signal:overdischarge Discharge undervoltage alarm, discharge undervoltageprotection protection, discharge due to single-ESM cell lowvoltage disconnection, and heavy load warning
