Abstract

A detachable battery system 02 for electric vehicles has packs of batteries in units with the coupling protrusion electrodes (0211,0221 figs 2,3) in contact to form a desired series and locked in position by supporting boards with anode and cathode contacts connected to a circuit connection control so that packs of battery units may be loaded onto a vehicle 01, or unloaded when in case packs. Battery units may be arrayed in series and separated by an insulating fireproof wall 023 (fig 2).

Description

DETACHABLE BATTERY SYSTEM FOR ELECTUUCVEECLES
This invention relates to a DBS, detachable battery system with detachable battery units for vehicle driving.
Electric vehicles suffer from the problem of prolonged length of recharging time.
Attempts to equip electric vehicles with detachable batteries meet with the problem of the need of a quick means of detachment and re-assembly.
According to the present invention, there is provided a battery comprising sub-battery units carried in a battery case, and assembled/connected by electrode protrusions and groove indentations so that the batteries run in series and by similar protrusion inden-
tation mechansim, the end batteries are connected to a circuit system for electricity supply for vehicle operation. Spring device for electrode contacts and ventilation grooves are present over the body of the batteries/cells. In the case of battery case, ventilation holes are also present. Cooling system such as cooling fan/s or coolant/air conditioning device is present.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Fig. I represents the side perspective of a vehicle 01 equipped with a detachable battery 02 at its back.
Fig.2 represents the aerial perspective of the component sub-unit batteries
arrayed in series and separated by an insulating fireproof wall 023.
Fig.3 represents two adjoining sub-unit batteries with coupling protrusion electrode 0211 and 0221.
Referring to the drawing, the detachable battery 02 contains battery units arrayed in double insulated rows of, say, 5 and separated by an insulating fireproof wall 023.
The electrodes 021 1, 0221 of each battery have copper covering for electricity conduction. Catch mechanisms for the battery units exist, for example, by floor slide protrusion and also making the battery unit bottoms slightly smaller than the rest of the unit body. To ensure proper stationing/position, stationing mechanism such as a metal bar is placed over the batteries with proper insulation and lock mechanism.
Electricity extraction is by connected the last anode of the battery series to a circuit connection by indentation- protrusion device. The cathode at the other end of the battery series is similarly connected to the circuit control.
For operation, the battery units are placed in a detachable case or fixed place for containing battery units. The battery units are placed in rows as described above and metal bar mechanism used to lock the battery units tightly. The cover of the battery case or fixed place is then closed.
(Note: The wall of each battery unit is normally made of fireproof plastic to give a tight grip at the electrode joints. The copper plates are attached by screwing method or by other ways such as heat-melt attachment to the plastic, etc. Where necessary the fireproof wall 023 has opening/s for electrode indentation-protrusion.)
Fig.4 further exemplifies an aerial perspective view of the floor set of battery units (comprising 3 cells connected in series, not shown). Not shown in the drawing are also ventilation grooves and grip mechanisms, e. g. spring catch device at the anode/ cathode connexions and rollers/roller balls and loading/unloading handles. Anti-
corrosion safety walls for with safety warning signs and words are not shown.
Combination of battery units can be fixed at, say, 6 battery units in 2 rows bound together to move at one go onto standard transport trolleys. Each set of battery unit combination can be fixed at desired places and connected by conductors to another set the same chamber (e.g. above each other) or in another chamber, using the proper connexion device. Referring to Fig. 4, a variant arrangement has one standard battery /cell 04 with a protrusion anode 41 at one end and an indented/holed cathode 42 at the other. Inside the indented/holed cathode 42 is spring device (e.g. a head contact plate with spring sets and similar side plates for bar shaped (taper-end) protrusion.)(not shown). The batteries/cells 04 are joined via their electrodes to fomm a series of say, 3 and the series are placed side by side at selected numbers to fomm a bound pack for loading/unloading purpose:e.g. grooves exist over the walls of the battery units for tying/binding purpose. Each series is in contact with another via alternating protrusions 411 and holes 422 similar to protrusion anodes 41 and indented/holed cathode 42, which have conducting connexions installed in supporting boards; circuit connectors/breakers are present in the connexions. (Fig. 4 shows an aerial perspective of batteries/cells arranged in series in between insulator boards 43; conducting conex-
circuit control and spring mechanism/device are not shown.)
