Large battery banks that are made up of numerous series-connected battery strings and have a maximum operational voltage of 800V and a maximum current of 40A power electric vehicles (EVs).
Control modules keep track of each cell’s voltage and, when necessary, apply the proper controls to keep voltage deltas across cells within a narrow tolerance. The inverter/motor, battery pack, and charging system high-voltage connections are managed by the junction box.
The Global EV Junction Box Enclosure market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Ampere EV announced that its High Voltage Junction Box is now ready for customer orders, bringing a new level of quality to the Plug-N-Play Electric Vehicle (EV) Conversion Market. For space-efficient high voltage power distribution in an electric car, Ampere EV designed the HVJB-5-400, Atom Drive Junction Box, in-house.
The Atom Drive Junction Box is a fantastic solution when space is restricted because it is constructed to OEM-level quality.
The Atom Drive Junction Box has several important features, including integrated high voltage interlock loop, fused high voltage accessory ports, main contactor, high voltage precharge circuit, and high voltage discharge circuit.
As a result, a single HVJB-5-400 can run one motor or other high-power component in addition to five high voltage accessories. Every high voltage connection is fused, and the battery’s high voltage outputs can be turned off using a negative contactor.
Busing made of copper that has been nickel-plated and is capable of carrying a high continuous current and resisting corrosion distributes the main power within the junction box.
The junction box casing and its electrical connections are acceptable for use in almost any vehicle environment since they comply with IP67 specifications for water and dust infiltration.
Sensata Technologies has unveiled new high-voltage junction boxes that are intended to deliver secure and dependable power distribution for commercial EVs that require high-power charging. The new DC charging boxes support 850 volts and 1,300 amps of megawatt charging for medium- and heavy-duty electric trucks.
