Problems solved by technology

Second, because Ni-MH has an exceptional energy density (i.e. energy is stored very compactly), heat dissipation is for example more difficult than for lead-acid batteries
This is because its surface area to volume ratio is much smaller than that of lead-acid batteries, which means that although Ni-MH batteries generate more heat than lead-acid batteries, the heat dissipation surface is reduced

Embodiment Construction

[0043] Disclosed herein is a modular battery system having multiple cells, preferably single cells, electrically interconnected by bus bars and mechanically interconnected by rails, and cooling headers. Referring to FIG. 1A , an embodiment of a modular battery system, generally referred to as 100 , is shown in which individual modules 101 are connected in series using bus bars 117 . Figure 1A shows a modular battery system comprising 24 battery modules 101 electrically wired in series. The 24 battery modules 101 are arranged in a 12×2 array. The modular battery system can be arranged and secured in a system housing 102 with an integrated control unit (ICU) 103 . The ICU 103 secures various components that may be used in a preferred embodiment of the system as described below. Each module 101 is preferably fastened between a pair of parallel rails. In this view, only the outer rail 110 is shown, however, a view of both rails can be seen with reference to Figure 5B. The modu...

Abstract

Disclosed herein is a modular battery system having at least one set of battery modules, preferably monoblock modules connected in series. Each of the battery modules may be designed with a first endplate and a second endplate, wherein each battery module is set between the first and second endplates and at least one band member couples the endplates to each other, binding the battery module between the endplates. The endplates are secured between a pair of rails and the system is disposed in a system housing. A cooling manifold provides a system wherein coolant flows into and out of each battery module. The system housing preferably has a coolant inlet and a coolant outlet. The cooling manifold is in flow communication with the coolant inlet and the coolant outlet. A battery monitoring system, which may include a battery control module and at least one remote sensing module, preferably monitors and collects performance and status information, such as voltage and temperature, of the battery modules. An integrated control unit (ICU) may be disposed in the system housing. The ICU supports electronics, some of which are used to collect electrical energy produced by the battery modules and / or monitor the system.

Description

technical field [0001] The present invention generally relates to improvements in rechargeable high performance batteries, modules and packs. In particular, the invention relates to multi-cell monoblock batteries incorporated into modular battery systems. Background technique [0002] Rechargeable nickel metal hydride (NI-MH) batteries are used in a variety of industrial and commercial applications such as fork lifts, golf carts, uninterruptible power supplies, pure electric vehicles, and hybrid electric vehicles. Vehicle applications include those related to propulsion as well as those related to starting, lighting and ignition. [0003] One aspect of battery operation that is particularly important for electric vehicle and hybrid vehicle applications is thermal management. Individual electrochemical cells are combined in close proximity in electric and hybrid vehicle applications. Many batteries are electrically and thermally coupled together. Therefore, the nickel met...
