It may be noted that the flat base (508) may comprise an anti-shock pad sandwiched between two welded metal sheet. The anti-shock pad may be made of a rubber or any shock absorption type PU material.
[0021] Further, as shown in the Figure 1, an enclosure (302) is mounted on the flat base (508) of the cart (506). The enclosure (302) comprises two side walls (314), two hydraulic doors (310), and a top cover (502). In an implementation, the enclosure (302) and the flat base (508) are made up of rigid metallic material. In another implementation, the enclosure (302) and the flat base (508) provides earthing protection to the system. The enclosure (302) and the flat base (508) are configured to provide a solid earth and a physical earth to the system. In one aspect, the enclosure (302) and the flat base (508) act as a return path for the earth. It is to be noted that the system may be used without requiring any external connection for earthing. In one implementation, the system may comprise an external earth connection. In one example, an earthing transformer may be added in the system for connection to large scale networks in order to protect the movable system. It may be noted that in an event of a fault, the fault current may be supplied to load or a source side.
[0022] Furthermore, the enclosure (302) may comprise a plurality of shelves (104) stacked within the enclosure (302). It may be noted that each shelf of the plurality of shelves (104) may be used to mount at least one of a battery, a hybrid inverter or a battery inverter (102), a temperature sensor (118), a humidity sensor (120), a GPS tracker, and a battery housing (106).
[0023] In one implementation, the enclosure (302) may comprise the battery housing (106) mounted at a center of the cart (506) and at a center of the flat base (508) of the enclosure (302). It may be noted that the battery housing (106) may be mounted in accordance with a center of gravity of the system. The battery housing (106) may be installed using a set of clamps insulated internally specially designed as per dimensions of the battery housing (106). The battery housing (106) may typically comprise a set of lithium ion batteries or cells (108). The number of batteries of lithium ion batteries or cells (108) may be configured based on power requirement and usage history. In an embodiment, the cells may be aligned on the flat base (508) to build a customised battery. In one example, a rubber vibration pad (110) may be placed in between the flat base (508) and the battery housing (106). The rubber vibration pad (110) is configured to dampen a vibration.
[0024] In one implementation, the enclosure (302) further comprises a hybrid inverter or a battery inverter (102) mounted above the battery housing (106). It may be noted that the hybrid inverter or the battery inverter (102) may be mounted on the shelf using clamps arrangement.

The hybrid inverter (102) is configured to input from the set of batteries or cells, solar, grid, Diesel Generator (DG) and any other load selected from the user. The hybrid inverter (102) is capable of converting AC to DC and DC to AC. In an example, when the set of lithium ion batteries or cells (108) are discharged the hybrid inverter (102) may take AC input and charge the DC batteries and cells. Similarly, when the set of lithium ion batteries or cells (108) are fully or partially charged and a power requirement is met, the hybrid inverter (102) supplies AC output to the user by converting the DC input from the set of lithium ion batteries and cells (108) into the AC output.
[0025] In one implementation, the enclosure (302) may further comprise a Battery Management System (BMS) (116). The BMS (116) may be mounted above the battery housing (106) on the shelf of the plurality of shelves (104). The BMS (116) may be electrically coupled to the set of lithium ion batteries or cells (108) and to the hybrid inverter or the battery inverter (102). The BMS (116) may be configured to monitor a health of the set of lithium ion batteries or cells (108). The BMS (116) may monitor parameters like battery temperature, charging time, output of each cell or battery, input of each battery or cell, and others. In an example, the BMS (116) may be connected to a computer, laptop, a mobile or any other data transferring device for accessing data stored in the BMS (116). In an embodiment, the data stored in the BMS (116) may also be displayed on a Human Machine Interface (HMI) (304) through on-board controller.
[0026] In one implementation, a temperature sensor (118) may be fitted within the enclosure (302) in order to monitor a temperature inside the enclosure (302). Similarly, a humidity sensor (120) may be fitted within the enclosure (302) to monitor a humidity level inside the enclosure (302). In order to control the temperature and the humidity inside the enclosure (302), a cooling unit (112) may also be installed on a side wall of the two side walls (314) within the enclosure (302). It may be noted that the cooling unit (112) is mounted away from the center of the enclosure (302). In an example, the cooling unit (112) may be mounted at the rear side of the cart (506). Example of the cooling unit (112) is an air conditioner, a ducting, a refrigeration unit, and others. In an event of an overheating of the set of lithium ion batteries or cells (108), the cooling unit (112) provides additional cooling to the enclosure (302) for protecting the set of lithium ion batteries or cells (108).
[0027] In an implementation, the enclosure (302) may comprise a controller configured to maintain the humidity and the temperature inside the enclosure (302) at a permissible value of humidity and the permissible temperature respectively. The controller may be electrically coupled to appliances like the set of lithium ion batteries or cells (108), the cooling unit (112), the BMS (116), the hybrid inverter or the battery inverter (102), and others. In an example, when the temperature inside the enclosure (302) rises above the permissible temperature, the controller automatically shuts off the appliances. It may be noted that the permissible temperature is based on operating temperatures of the set of lithium ion batteries or cells (108), the hybrid inverter or the battery inverter (102), the BMS, the cooling unit (112) and the temperature sensor (118). In an example, the permissible temperature may be a cumulative of the temperatures of all the appliances.
[0028] The controller is further configured to automatically shut off the appliances when the humidity level inside the enclosure (302) rises above the permissible value or during critical faults. Example of the critical faults may include overheating of one or more appliances, fire breakout, failure of the one or more appliances, and others.
[0029] In one implementation, the enclosure (302) further comprises a firefighting arrangement in order to protect the appliances inside the enclosure (302). The firefighting arrangement may be configured to automatically trigger the controller during a fire or a smoke incident inside the enclosure (302). It may be noted that the controller may shut of the appliances in real time upon receipt of the trigger from the fire fighting arrangement. In one example, the firefighting arrangement may be accessible to the user via the HMI (304). In one embodiment, the firefighting arrangement may comprise a set of heat and smoke detector sensors placed at each equipment. The set of heat and smoke detector sensors are configured to sense fire in the enclosure (302) and signal the controller for quick release of fire fighting gas or powder. It may be noted that the firefighting arrangement may operate in at least one of a manual and an auto mode. The firefighting arrangement may also have an abort function in case of a false alarm.
[0030] In one implementation, the enclosure (302) further comprises an electrical protection arrangement having a set of Miniature Circuit Breakers (MCB (306)) (306) and a set of Molded Case Circuit Breaker (MCCB) for low voltage and low current. Similarly, the electrical protection arrangement may comprise an Air Circuit Breaker (ACB) and a High Voltage Circuit Breaker (HVCB) for higher voltage and higher current. The MCB (306), MCCB, ACB and HVCB may be mounted on the at least one side wall from an outer side of the enclosure (302). The MCB (306) and the MCCB are used for shutting power circulation to and from the system.
[0031] In another implementation, the controller is programmed with a set of operating modes. Example of the operating modes are a battery mode, a solar mode, a grid mode, a bypass mode, and a generator mode. It may the noted that controller is configured to select the at least one mode based on an available power at the set of lithium ion batteries or cells (108) and a load requirement.
[0032] In the load mode, the controller utilizes power from the set of lithium ion batteries or the cells (108) to meet the load requirement. In the solar mode, when the solar power is available, the controller directly provides power to the load and afterwards charge the set of lithium ion batteries or cells (108). In an embodiment, the controller may utilize partial power from the solar and remaining power from the set of lithium ion batteries or cells (108). The hybrid inverter (102) is used in the solar mode.
[0033] In the bypass mode, when the grid power is available, the controller may directly feed the load and the system is used as a backup. The bypass mode may be used when the cart (506) is stationed at any premise or any at a place. In bypass mode, a power electronics circuit may bypass the grid power to the load directly and hence minimal energy loss may be incurred. In the generator mode, the load may be fed directly from the DG.
[0034] In an implementation, the appliances, the firefighting arrangement and the controller may be mounted on the vibration pads (110) for absorbing the vibration. It may be noted that the appliances, the firefighting arrangement and the controller may be mounted using the set of clamps designed specifically for each of the appliances, the firefighting arrangement and the controller. In an embodiment, the clamps may be provided with an additional vibration pad stuck inside the clamps. The additional vibration pad may offer additional cushioning to the appliances, the firefighting arrangement and the controller. The additional vibration pad may also absorb the shock and dampen the vibrations.
[0035] In one implementation, the enclosure (302) may comprise of cables to electrically connect the appliances, the firefighting arrangement and the controller. The cables are jacketed in an insulated pipe and are well insulated. The cables are shock proof, fireproof and tamper proof. All electrical connections between battery, inverter or hybrid inverter (102), inputs, outputs etc. are specifically made male-female type with fixing arrangement or lock in type. In one example, the electrical connections may also be monitored for any temperature rise due to lose connection.
[0036] Referring now to Figure 2, the suspension mechanism of the movable energy management system (500) is disclosed. As shown, the flat base (508) is mounted on top of a chassis (206). The chassis (206) is connected to the wheels (202). It may be noted that due to installation of the appliances, the cart (506) becomes heavy. In order to maintain the appliances safe and secure, it is a paramount to balance cart (506) weight and also to maintain an alignment of the cart (506) on the road. In order to provide the balance, the suspension mechanism provides a pair of shock absorbers (204) connected between the chassis (206) and the pair of wheels (202). The pair of shock absorbers (204) is configured to provide a weight balance support to the cart (506).
