Product Overview

SECC 2.0 developed by our company, the product is optimized based on the firstgeneration SEC C 1.0 product, Remove the extended hardware interfaces (such as voltageand current temperature detection), Add some necessary functional circuits and hardwareinterfaces (such as to meet the charging requirements of the American standard, Added acircuit CC signal measurement circuit, Increased storage capacity, Can realize various logsand record storage, etc.), And reduced the size of the circuit board, At the same time, itadded the support for ISO15118 DC EIM and AC EIM protocol on the software, So that it canalso be applied to AC charging piles.
