CEMO fireproof battery charging cabinet Premium Plus 8/10 - 1 /3-phase

Size, structure and function of the storage cabinet

This version of the CEMO battery charging cabinet is a storage and charging system. The external dimensions are 890 x 660 x 1110 mm (1-phase) or 950 x 660 x 1110 mm (3-phase), the internal dimensions 730 x 530 x 880 mm, the weight 136 kg.

Differences to the Basic charging cabinet

In contrast to the CEMO Basic 8/5 battery charging cabinet, the smoke detector in this version is powered by electricity. In addition, however, the currentless circuit is also included in the smoke detection, a potential-free output for connection to the fire alarm system on the outside of the cabinet, as well as a 12V connection option for accessories such as a combination alarm unit (optical and acoustic).

In addition to the Premium version

The Premium Plus version of the CEMO battery charging cabinets also has an integrated interior temperature display and remote alerting to a cell phone (using a SIM card). Additional functions are also possible via remote access.

Features

In the premium version, the charging cabinet has an alarm, a smoke detector with potential-free output for an alarm signal and technical ventilation. If heat and/or smoke develops, the power circuit is interrupted. If the door is opened, the power supply is also interrupted by means of a door contact switch. The doors should therefore always be closed during the charging process.

These are charging variants with 2 vertically arranged 4-way socket strips for the power supply. Either with a 230 V version with 1-phase power supply (3500 W / 16 A) or the 400 V version with 3-phase power supply (2x 3500 W / 2x 16 A).

In the Premium version, the charging cabinet has an acoustic warning tone, heat dissipation during charging with the aid of the built-in fan and a charging stop in the event of a fault or damage. If heat builds up, the power circuit is interrupted by a power-off circuit. If the door is opened, the power supply is also interrupted by means of a door contact switch. The doors should therefore always be closed during the charging process. In addition, the Premium version has an improved connection option for combination alarm devices (12V) and a connection to a fire alarm system.

Equipped with the CEMO lockEX lock

CEMO lockEX is an innovative mechanism in the door lock that reliably relieves the pressure of flammable gases inside the cabinet in a controlled manner to effectively prevent explosions.

The design is based on an intelligent spring mechanism which, in the event of a damaged Li-battery exploding, gently opens the enclosure doors to release the resulting pressure and then immediately closes them securely again.

The protection granted by the German Patent and Trademark Office is particularly important here. It has long been known among experts that lithium batteries can not only cause flames and explosive burning of individual cells, but also a gas explosion due to leaking cell vapors. This is the worst case scenario in the event of a battery fire, as it can nullify the entire protective effect in case of doubt and can therefore be the most decisive criterion in the risk assessment.

CEMO lockEX combines fire protection and explosion protection in one product and offers a reliable solution for dealing with potentially dangerous battery fires.

The lockEX technology effectively interrupts the progress of a battery fire. An explosion can occur even before a thermal runaway begins. If the enclosure housing gives way or the doors open, the protective effect can be lost immediately and the burning cells and battery packs are propelled unhindered into the environment at the installation site.

CEMO's lockEX mechanism ensures that the explosion pressure that builds up inside the enclosure is effectively managed. This advanced NO-BANG technology ensures that protection is fully maintained, even in the worst-case scenario of a battery fire.

Up to 3-phase

The 3-phase version is required if, for example, batteries are to be charged with fast chargers that have a greater power requirement than the 1-phase version can provide.

Well equipped in the event of an accident

Critically damaged lithium-ion cells in particular can pose a serious risk to people and equipment in the event of a fire ("thermal runaway"). Dust caused by these fires can settle on the circuit boards of production and operating devices and damage them permanently. This charging cabinet has an MPA-tested fire resistance over 60 minutes from the inside to the outside in accordance with DIN EN 1363-1. A real battery fire test was carried out with an independent university. The air inlet and outlet openings close automatically in the event of fire. However, the doors should always remain closed during use.

Robust construction

The charging cabinet is made of robust, fire-resistant components. Special fire protection seals prevent flames from escaping and it has a cold smoke-tight closure system for the openings. The doors are double-leaf and lockable with sturdy locking and suspension. the doors are painted in orange, similar to RAL 2004, and the body in gray, similar to RAL 7035.

Portable use

The container can be stacked to a height of 3 units. The stacking feet make it possible to drive underneath. As an option, the container can also be fitted with an additional, fire-resistant and tested cable gland, for example to connect to the in-house fire alarm system.

Guidelines

There are currently no legal regulations for the storage of lithium batteries / lithium-ion batteries. Only VdS Schadenverhütung GmbH issues general safety rules for damage prevention in its publication VdS 3103 : 2019-06 (03), and it is advisable to clarify your requirements with your property insurance company in advance.

The manufacturer

CEMO GmbH from Weinstadt has stood for safe storage with imagination and energy for more than 60 years. The company is a pioneer in the field of modern transportation and storage container technology and is one of the market leaders in this area.

Future-oriented

Lithium-ion batteries will be indispensable in all industrial applications in the coming years. However, if used improperly, batteries can pose a potential hazard during production, storage and transportation that should not be underestimated. By purchasing this storage cabinet, you protect yourself against major financial losses right from the start.
